Integration between Planview EPMO to Google BigQuery and Tableau

extracting data from Planview using their REST API with Python, ingesting into BigQuery via Cloud Composer, and visualizing with Tableau for the Enterprise Project Management Office (EPMO) at Pratt & Whitney. This narrative highlights your technical approach while aligning with business outcomes like Delivering Sustainable Profits (DSP).

Planview Data Integration Framework – Enabling Enterprise Project Visibility

To support the Enterprise Project Management Office (EPMO) in delivering strategic visibility across all business lines, Pratt & Whitney implemented a robust data integration framework to extract, transform, and visualize project portfolio data from Planview using a modern cloud-native stack.

1. Data Extraction Framework using Python:

A modular Python-based framework was developed to connect with Planview’s REST API, authenticate via OAuth 2.0, and extract key financial and project performance datasets.

• Key Components:
• Configurable API client with token refresh mechanism
• Modular extract classes for financials, resource allocations, milestones, and forecasts
• JSON normalization and schema mapping for downstream ingestion
• 
  

This allowed for flexible extension and reuse across Planview endpoints as new business requirements emerged.

2. Ingestion Pipeline via Cloud Composer (Apache Airflow):

To orchestrate data flow into the enterprise warehouse:

• Cloud Composer (Airflow) DAGs were scheduled daily to:
• Trigger Python extraction scripts
• Stage raw data in Google Cloud Storage (GCS)
• Load curated tables into Google BigQuery, partitioned by load date and business unit
• 
  

Airflow also managed retries, logging, and alerting to ensure reliability and data traceability.

3. Secure Visualization with Tableau:

The curated BigQuery datasets were consumed by Tableau dashboards tailored for the EPMO and business leaders. These dashboards provided:

• Real-time project financial health
• Portfolio performance across programs and geographies
• Milestone tracking and funding utilization
• Executive pulse views aligned with DSP (Delivering Sustainable Profits) goals

Role-based access controls ensured that data was securely segmented by business line and organizational role.

Outcome:

This integrated framework enabled a single source of truth for project and financial performance across the enterprise, improved executive decision-making, and supported the DSP initiative by exposing delays, risks, and budget overruns in real time.

Tableau to Power BI migration

Migrating from Tableau to Power BI is a bit complex due to the differences in their underlying architectures, APIs, and file formats. While there’s no official one-click migration tool from Tableau to Power BI, you can automate parts of the process using Python, REST APIs, and third-party tools.

Here’s a breakdown of what you can do and how to approach building a migration script using Python:

Step 1: Extract Metadata from Tableau

Use the Tableau REST API and Metadata API (GraphQL) to extract workbooks, datasources, and visualization metadata.

Python Example (Tableau Metadata API):

Use Python libraries like gql or requests to send this GraphQL query.

Step 2: Parse and Convert the Metadata

Translate the Tableau metadata into something Power BI understands. This requires custom mapping logic:

• Tableau Viz → Power BI Visual
• Tableau Filters → Power BI Slicers
• Tableau Data Sources → Power BI Dataflows or imported datasets

You can write this logic using pandas or custom JSON translators.

Step 3: Use Power BI REST API to Create Equivalent Artifacts

Power BI’s REST API supports operations like:

• Creating workspaces
• Uploading PBIX files
• Updating datasets
• Managing reports

However, you cannot programmatically create detailed visuals via REST API alone — that requires Power BI Desktop and the PBIX format.

But you can prepare data and models using:

• Power BI XMLA endpoint
• Tabular Editor (for datasets)
• Power BI Desktop Automation using PowerShell/Python & PBIX Templates

Alternative/Third-party Tooling

Some tools that can help in this migration:

• Power BI XMLA/Tabular Editor: To create models programmatically.
• Tableau to Power BI Migration Tool by MAQ Software (limited features).
• ZappySys ODBC Drivers / ETL tools to extract Tableau data and push to Power BI.
• Alteryx or KNIME: As middle-layer ETL tools.

Caution

• Visuals cannot be directly migrated — you’ll need to recreate them.
• Some calculations (e.g., LOD in Tableau) must be translated manually into DAX.
• Tableau dashboards (layouts, interactivity) won’t be 1:1 with Power BI.

Want a Starter Script?

If you’re interested, I can generate a Python starter script that:

• Authenticates with Tableau
• Extracts workbook metadata
• Prepares a mapping JSON for Power BI

Let me know how automated you want it (full flow vs metadata only).

Alteryx publish to tableau should be precision

Based on the screenshot, it looks like you’re using Alteryx to transform data and then write the results to a Tableau output file. The errors shown—particularly “Precision above arrows supported max” (or “Precision above supported max”)—usually mean that at least one numeric field in your workflow exceeds the allowable precision/scale for the output format. In other words, Alteryx is trying to push a decimal value that’s too large or too precise for the Tableau output tool to handle.

Below are some steps and tips to resolve these issues:

Tableau Server Extract all workbooks attributes

Convert Tableau Server Client Workbooks List to Pandas DataFrame

When you use the Tableau Server Client (TSC) to get all workbooks from the server:

all_workbooks = list(TSC.Pager(server.workbooks))

You get a list of workbook objects. Each object has attributes like id, name, project_name, owner_id, etc.

Convert all_workbooks List to Pandas DataFrame:

import pandas as pd

import tableauserverclient as TSC

# Assuming you already have `all_workbooks` as a list

all_workbooks = list(TSC.Pager(server.workbooks))

# Extracting relevant attributes into a list of dictionaries

workbooks_data = [

  {

    'id': wb.id,

    'name': wb.name,

    'project_name': wb.project_name,

    'owner_id': wb.owner_id,

    'created_at': wb.created_at,

    'updated_at': wb.updated_at,

    'size': wb.size,

    'show_tabs': wb.show_tabs,

    'webpage_url': wb.webpage_url,

  }

  for wb in all_workbooks

]

# Convert to DataFrame

df = pd.DataFrame(workbooks_data)

print(df)

Explanation:

• List comprehension: Extracts key attributes from each WorkbookItem object.

• Attributes commonly used:

• wb.id

• wb.name

• wb.project_name

• wb.owner_id

• wb.created_at

• wb.updated_at

• wb.size

• wb.show_tabs

• wb.webpage_url

You can customize this list based on the attributes you need from the WorkbookItem object.

Sample Output:

         id      name   project_name    owner_id      created_at ... size show_tabs           webpage_url

0 abcd1234efgh5678   Sales Report Finance Project user123456789 2023-10-01 08:00:00 ... 2500   True https://tableau.server/view/...

1 wxyz9876lmno5432 Marketing Data Marketing Group user987654321 2023-11-05 10:30:00 ... 3100   False https://tableau.server/view/...

Key Notes:

• Make sure you import pandas and tableauserverclient.

• This approach is efficient and works well with TSC.Pager() results.

• You can easily export the DataFrame to CSV or Excel:

df.to_csv('tableau_workbooks.csv', index=False)

Would you like help with pagination handling, filtering specific workbooks, or exporting the DataFrame?

Automating tableau bulk connection

It is technically possible to use a tool like Selenium to automate the browser‐based creation of a BigQuery connection in Tableau—complete with entering a custom query and performing bulk connection operations—but there are several important caveats to consider:

What You Can Do with Selenium

• Browser Automation:

Selenium (or a similar browser automation tool) can control Chrome (or another browser) to log into Tableau Server or Tableau Cloud, navigate the UI, and simulate the manual steps you’d normally take to create a connection. This means you could script the process of:

• Signing into Tableau.

• Navigating to the data connection or data source creation page.

• Selecting Google BigQuery as the connection type.

• Entering or uploading service account credentials.

• Inserting a custom SQL query.

• Repeating these steps in a loop to handle bulk operations.

• Bulk Operations:

With careful scripting, you can iterate over a list of parameters or queries, effectively automating the creation of multiple connections. This could be useful if you need to deploy many similar connections at once.

Challenges and Considerations

• Brittleness:

UI automation is inherently fragile. Any change to the Tableau web interface (such as layout, element identifiers, or workflow changes) can break your Selenium script. This means you’ll have to invest time in maintaining your automation scripts.

• Lack of Official Support:

Tableau does not officially support UI automation for creating or managing connections. The REST API and Tableau Server Client (TSC) library are the recommended and supported methods for automating Tableau tasks. If those APIs do not expose exactly the functionality you need (for example, the embedding of a custom query in a connection), that might force you to consider UI automation—but keep in mind the risks.

• Authentication & Security:

Automating through the browser may require handling authentication (and possibly multi-factor authentication) in a secure manner. Ensure that any credentials or service account keys are managed securely and not hard-coded in your automation scripts.

• Complexity of Custom Queries:

If your process involves creating custom SQL queries as part of the connection setup, you’ll need to script the logic to input these queries correctly. Any errors in the custom query syntax or its integration into the Tableau UI may not be easily recoverable from an automated script.

Recommended Alternatives

• Tableau REST API / TSC Library:

Before resorting to Selenium, review whether you can accomplish your goal using Tableau’s REST API or the Tableau Server Client library. Although these APIs may not let you “create a connection from scratch” in every detail (especially if you need to embed non-standard elements like a custom query), they are far more stable and supported for bulk operations.

• Hybrid Approach:

In some cases, you might use a combination of API calls (for publishing and updating data sources) and lightweight browser automation to handle any remaining steps that the API cannot cover. This minimizes the parts of the process that rely on brittle UI automation.

In Summary

Yes, you can use Selenium or a similar tool to automate the creation of a BigQuery connection (including entering a custom query and handling bulk connections) by automating browser interactions in Chrome. However, this approach is generally less robust and more error-prone than using the officially supported Tableau REST API or TSC library. If you choose the Selenium route, prepare for additional maintenance and troubleshooting as Tableau’s web interface evolves.

For more details on Tableau’s supported automation methods, see the official Tableau REST API documentation ( ).

Tableau export workbooks

Tableau’s REST API does not natively support exporting workbooks, images, or PDFs directly. However, you can achieve this using a combination of Tableau REST API and the Tableau Server Client (TSC) or the JavaScript API. Here’s how:

1. Export a Tableau Workbook (TWB or TWBX)

You can export a workbook using the REST API by downloading it from Tableau Server:

Endpoint:

GET /api/3.15/sites/{site_id}/workbooks/{workbook_id}/content

Steps:

1. Authenticate using Tableau’s REST API (/auth/signin).

2. Get Site ID & Workbook ID from /sites and /workbooks.

3. Download the Workbook using the content endpoint.

Example using Python:

import requests

TABLEAU_SERVER = "https://your-tableau-server"

TOKEN = "your-auth-token"

SITE_ID = "your-site-id"

WORKBOOK_ID = "your-workbook-id"

url = f"{TABLEAU_SERVER}/api/3.15/sites/{SITE_ID}/workbooks/{WORKBOOK_ID}/content"

headers = {"X-Tableau-Auth": TOKEN}

response = requests.get(url, headers=headers)

if response.status_code == 200:

  with open("workbook.twbx", "wb") as file:

    file.write(response.content)

  print("Workbook downloaded successfully.")

else:

  print("Failed to download workbook:", response.text)

2. Export Image or PDF using REST API

The REST API doesn’t support direct PDF/image export, but you can use the Tableau Views API:

Export Image (PNG)

GET /api/3.15/sites/{site_id}/views/{view_id}/image

Export PDF

GET /api/3.15/sites/{site_id}/views/{view_id}/pdf

Example in Python (Export Image):

VIEW_ID = "your-view-id"

url = f"{TABLEAU_SERVER}/api/3.15/sites/{SITE_ID}/views/{VIEW_ID}/image"

response = requests.get(url, headers=headers)

if response.status_code == 200:

  with open("view.png", "wb") as file:

    file.write(response.content)

  print("Image exported successfully.")

else:

  print("Failed to export image:", response.text)

Example in Python (Export PDF):

url = f"{TABLEAU_SERVER}/api/3.15/sites/{SITE_ID}/views/{VIEW_ID}/pdf"

response = requests.get(url, headers=headers)

if response.status_code == 200:

  with open("view.pdf", "wb") as file:

    file.write(response.content)

  print("PDF exported successfully.")

else:

  print("Failed to export PDF:", response.text)

Alternative: Tableau Server Client (TSC)

Tableau Server Client (TSC) is a Python library that simplifies these operations.

Install it:

pip install tableauserverclient

Example (Download Workbook):

import tableauserverclient as TSC

TABLEAU_SERVER = "https://your-tableau-server"

USERNAME = "your-username"

PASSWORD = "your-password"

SITE_ID = "your-site-id"

WORKBOOK_ID = "your-workbook-id"

server = TSC.Server(TABLEAU_SERVER, use_server_version=True)

auth = TSC.TableauAuth(USERNAME, PASSWORD, SITE_ID)

with server.auth.sign_in(auth):

  workbook = server.workbooks.get_by_id(WORKBOOK_ID)

  server.workbooks.download(workbook.id, filepath="workbook.twbx")

  print("Workbook downloaded.")

Tableau and google analytics integration

Yes, you can use Google Analytics (GA) to track user navigation and interactions on Tableau Server dashboards, but there are some important considerations:

Approaches to Track Tableau Server Usage with Google Analytics

1. Using Google Analytics JavaScript in Tableau Web

• If your Tableau dashboards are embedded in a web application, you can add Google Analytics tracking scripts to the web pages.

• This will allow GA to capture user navigation, page views, and interactions.

• Example: If your dashboards are embedded using Tableau’s JavaScript API, you can include GA’s tracking script on the hosting web page.

✅ Best for: Tableau dashboards embedded in web apps.

❌ Not possible for: Native Tableau Server (no direct GA script injection).

2. Tracking User Activity via Tableau Server Logs

• Tableau Server itself does not support Google Analytics natively, but you can track user navigation via Tableau’s usage logs.

• You can extract data from:

• Tableau Repository (PostgreSQL DB) → Tracks logins, dashboard views, and user interactions.

• VizQL Server Logs → Records detailed interactions.

✅ Best for: Internal Tableau Server usage tracking.

❌ Doesn’t provide: Real-time analytics like GA.

3. Using Google Tag Manager (GTM) for Embedded Tableau Dashboards

• If Tableau dashboards are embedded in a web portal, you can use Google Tag Manager (GTM) to track events like:

• Page loads

• Button clicks

• Dashboard filters applied

✅ Best for: Embedded dashboards where GTM is implemented.

❌ Not applicable: Directly within Tableau Server.

Alternative: Tableau Server Built-in Monitoring

• If GA is not an option, consider Tableau Server’s built-in monitoring:

• Admin Views → Provides insights into user activity.

• Custom SQL Queries on Tableau Repository → Query historical_events, http_requests, etc.

• Third-Party Monitoring Tools → Tools like New Relic or Splunk can provide similar insights.

Conclusion: Can You Use GA in Tableau Web?

✔ Yes, if Tableau dashboards are embedded in a web app (via JavaScript API + GA tracking).

❌ No direct GA tracking for standalone Tableau Server dashboards (use Tableau logs instead).

Tableau Audit user downloads

Tableau Server and Tableau Cloud provide auditing capabilities that can help track user activities, including exporting data. To detect or list users who have downloaded/exported data, you can use the following approaches:

1. Using Tableau’s Administrative Views

Tableau Server and Tableau Cloud offer built-in administrative views to monitor user activities. The “Actions by All Users” or similar admin dashboards include data about downloads:

• Navigate to the Admin Insights section in Tableau Server/Cloud.

• Look for actions such as “Export Data” or “Download Crosstab.”

• Filter the data to identify the users and their activity timestamps.

2. Using Tableau Server Repository (PostgreSQL Database)

Tableau Server stores detailed event logs in its repository (PostgreSQL database). You can query the repository to identify users who downloaded/exported data. Use a query similar to:

SELECT 

  u.name AS username,

  w.name AS workbook_name,

  v.name AS view_name,

  eh.timestamp AS event_time,

  eh.action AS action

FROM 

  historical_events eh

JOIN 

  users u ON eh.user_id = u.id

JOIN 

  views v ON eh.target_id = v.id

JOIN 

  workbooks w ON v.workbook_id = w.id

WHERE 

  eh.action = 'export.crosstab' -- or 'export.data' depending on the action

ORDER BY 

  event_time DESC;

Note: Access to the Tableau repository requires enabling repository access via Tableau Server settings.

3. Using Tableau’s Event Logs

Tableau generates event logs for all user activities. You can parse these logs to find export/download events. The logs are located in the Tableau Server’s logs directory. Search for keywords like "export.crosstab" or "export.data" in the logs.

4. Custom Tableau Dashboard for Monitoring Exports

Create a custom dashboard for monitoring exports by connecting to the Tableau Server repository. Use visualizations to track user activity, including export/download actions.

5. Third-Party Tools or APIs

If you prefer more granular monitoring, use:

• Tableau REST API: Fetch audit data using the Query Workbook or View Activity endpoints.

• Tableau Metadata API: Extract detailed information about user interactions and exported data.

Prerequisites:

• Admin or Site Admin access is required for the repository or admin views.

• Enable Auditing in Tableau Server to ensure activity logs are captured.

Tableau group column differences

In Tableau, you can calculate the difference between values in the same column, grouped by another column, by using Table Calculations. Here’s how you can achieve this:

Steps to Calculate Row Difference in Tableau:

1. Drag your data fields to the canvas:

• Place the grouping column (e.g., Category) in the Rows or Columns shelf.

• Place the measure column (e.g., Sales) in the Columns or Rows shelf.

2. Add a Table Calculation for Difference:

• Right-click on the measure (Sales) and select Quick Table Calculation > Difference.

• This will calculate the difference between consecutive rows of the same column.

3. Customize the Table Calculation:

• Right-click on the measure again, select Edit Table Calculation.

• Under “Compute Using,” choose how the difference should be calculated:

• If your data is grouped by a column, choose Specific Dimensions and ensure only the grouping column (e.g., Category) is selected.

• This ensures the calculation restarts for each group.

4. Sort Data Appropriately:

• Ensure the rows are sorted correctly for the difference to make sense. For example, if calculating the difference by date, sort by the date field in ascending order.

Example

Category Date Sales Difference

A 2024-12-01 100 -

A 2024-12-02 150 50

A 2024-12-03 200 50

B 2024-12-01 300 -

B 2024-12-02 250 -50

• Group by Category.

• Compute difference on Sales.

If you want a custom calculation without Table Calculations, you can write a calculated field using LOD (Level of Detail) or Window functions. Let me know if you’d like help with that!

Creating Dynamic Gannt Chart in Tableau

Yes, Tableau can create a dynamic Gantt chart from rows of dates and states. Gantt charts in Tableau are commonly used to visualize project timelines, progress, or task states over time.

Steps to Create a Dynamic Gantt Chart in Tableau

1. Prepare Your Data:

• Ensure your data has rows with at least a start date, end date (or duration), and a state (e.g., “In Progress,” “Completed,” etc.) for each task or project milestone.

• For Gantt charts, Tableau expects at least a start date and duration or end date to calculate the bar lengths.

2. Connect to Your Data Source:

• Import your data into Tableau and verify that the date fields are recognized as Date types.

3. Set Up the Gantt Chart:

• Rows: Drag a unique identifier for each task (like Task ID or Task Name) to the Rows shelf.

• Columns: Drag the start date to the Columns shelf to set the starting point of each Gantt bar.

• Marks Type: Set the Marks type to Gantt Bar.

4. Define Duration (Optional):

• If your data has only a start date, you’ll need a calculated field to represent the task duration. For example:

DATEDIFF('day', [Start Date], [End Date])

• Drag this calculated duration field to the Size shelf to adjust the length of the Gantt bars based on task length.

5. Add Task States for Color Coding:

• To add states dynamically, drag the State field (e.g., “In Progress,” “Completed”) to the Color shelf. This allows each bar to reflect the task’s state dynamically.

6. Add Filters for Interactivity:

• You can add filters for date ranges, specific task categories, or state filters to make your Gantt chart dynamic, allowing users to focus on specific tasks or time periods.

7. Adjusting the Timeline:

• Use the Pages shelf or add interactive date filters to dynamically control which date range is displayed, giving a real-time update based on selected dates.

Example Use Cases

This approach allows you to track project phases, visualize timelines for ongoing tasks, and quickly assess the status across various tasks. Tableau’s flexibility with Gantt charts enables rich customization and interactive functionality for exploring complex project timelines and status indicators .

Sales Pitch: Using Gantt Charts in Tableau for Project Management Success

In today’s fast-paced business world, managing projects efficiently and staying on top of deadlines is crucial. A Gantt chart is one of the best tools for tracking project timelines and task progress — and Tableau takes this visualization to the next level.

Here’s why Gantt charts in Tableau are the game-changer your team needs:

1. Visualize Your Project Timeline with Clarity

With Tableau, a Gantt chart instantly provides a clear view of your project’s timeline, breaking down individual tasks, their durations, and dependencies. It gives you a snapshot of where each task stands — what’s on track, what’s delayed, and what’s coming next — all in one visual.

It’s like a real-time, visual roadmap for your project, ensuring no detail is overlooked.

2. Interactive and Dynamic Visualization

Unlike static Gantt charts, Tableau’s interactive charts allow you to:

• Zoom into task details, explore timelines, or drill down into specific subtasks or milestones.

• Use filters to customize the view by department, team, or priority.

• Adjust your project plan in real time as changes happen, empowering better decision-making with the most up-to-date information.

3. Comprehensive Data Integration

Tableau allows you to blend multiple data sources, meaning you can combine project management data from tools like Excel, databases, or online project management systems into a single, actionable Gantt chart. This means your chart isn’t just about dates — you can track:

• Resource allocation

• Costs and budget

• Task completion percentages

4. Enhance Team Collaboration

With Tableau’s easy sharing capabilities, Gantt charts can be shared securely across teams or departments. Keep everyone — from project managers to stakeholders — on the same page with a real-time, data-driven view of your project. Everyone can view the latest updates and make more informed decisions, fostering smoother collaboration and accountability.

5. Customization and Branding

In Tableau, your Gantt chart can be fully customized to reflect your company’s branding and project needs. Whether you want to incorporate corporate colors or logos (like in our Qatar Airways-themed example), or focus on specific KPIs, you have full control over the design and data presentation.

6. Easily Track and Manage Dependencies

One of the most powerful features of a Gantt chart is the ability to visualize task dependencies. Tableau’s Gantt chart makes it easier to manage critical paths, so you can focus on the tasks that could delay the project. Early visibility into potential bottlenecks helps ensure timely interventions, keeping projects on track and within scope.

7. Increase Efficiency and Reduce Risks

By monitoring progress with Gantt charts, you can identify risks early and reallocate resources or adjust schedules to avoid project delays. This proactive project management leads to improved efficiency, fewer last-minute surprises, and a smoother overall execution.

In Summary:

A Gantt chart in Tableau is not just a static timeline — it’s an interactive, real-time project management tool. It provides clarity, insight, and flexibility, ensuring your projects stay on track, on budget, and on time. By integrating multiple data sources, customizing views, and fostering team collaboration, Tableau’s Gantt charts empower your organization to manage projects more effectively.

Make your next project a success — with Gantt charts in Tableau.

By leveraging the power of Tableau’s visualizations, your project management process will move from reactive to proactive, giving you the competitive edge.

We plot maps using geographic fields. A field is recognized as a geographic field in Tableau by assigning it a geographic role. These geographic fields can instantly be spotted using the globe icon right before the field name.

(Examples of geographic fields)

We plot maps by dragging the geographic fields to the detail shelf. In this case, have dragged the field State to the detail shelf – to plot State map.

Note: Because of one of the two reasons above – am getting a blank view with 49 unknowns on the bottom right.

How do you fix this?

To fix this – check your map location first.

1. Editing Location

To edit your map location – go to Map menu >> Edit Locations …

On the dialogue box – ensure that the correct location is chosen. In this case, have changed my Country/Region to United States – simply because the data I need to plot is based on that geographic area.

(Note: This does not give the solutions am looking for. This is because Tableau is still unable to match the locations in my data. Hence returning the fields as ‘Unrecognized’ - therefore I need to troubleshoot further)

2. Assign the correct geographic role

To view the currently assigned geographic role – click on the globe icon (or right click on the field) >> Geographic Role >> see what is assigned.

In this case, am able to spot the problem with my map – that is the field State has been assigned geographic role of Zip Code/Postcode instead of State/Province.

Assigning the correct geographic role, I have.

This can be used to perform spatial analysis by adding different measures.

(In this case, have added Profit to the color shelf)
