Question details

The user needs to retrieve and display Project Online Custom Enterprise Fields and WBS data within a Power Apps gallery.

Product
Power Apps / Project Online
Device & OS
not provided
Scenario
Building an application in Power Apps and attempting to use the ProjectOnline.ListTasks connector to pull custom fields from Project Web App (PWA).
Observed behavior
Fields such as WBS and custom enterprise fields are not accessible or visible in the gallery when using the standard ProjectOnline.ListTasks connector.
Before you start

Ensure your custom enterprise fields are correctly published in the Project Web App (PWA) environment and verify your Power Apps connection credentials before troubleshooting API limitations.

Solution 1Recommended

Consult the Power Platform Community for Connector Alternatives

Because the standard ProjectOnline.ListTasks connector has limitations regarding custom enterprise fields and WBS, consulting specialists in the Microsoft community is the best way to find alternative APIs or custom connector solutions.

The out-of-the-box Project Online connector for Power Apps does not expose all custom enterprise fields or specific structural fields like WBS. Resolving this typically requires leveraging the Project Online REST API via Power Automate or creating a Custom Connector.

1
Document the missing fields

Make a comprehensive list of the specific WBS and custom enterprise fields you are trying to query from your Project Web App.

2
Visit the Power Platform Community

Navigate to the official Microsoft Power Platform Community forums where API and connector experts provide tailored workarounds.

3
Submit your query

Post your specific scenario on the forum (e.g., https://community.powerplatform.com/forums/) asking for guidance on alternative APIs, HTTP request configurations, or custom connectors to retrieve your PWA data.

REST API Alternative: Many developers bypass the ListTasks connector entirely by using a Power Automate flow to make an HTTP request to the PWA OData feed, which can successfully return custom enterprise fields.

Frequently Asked Questions

Can the ProjectOnline.ListTasks connector retrieve custom enterprise fields by default?

No, the standard ProjectOnline.ListTasks connector in Power Apps typically only exposes default task fields. Retrieving custom enterprise fields usually requires utilizing the Project Online REST API directly.

How do I access the Project Online REST API for Power Apps?

You can access the REST API by either creating a Custom Connector in Power Apps or by using Power Automate to send HTTP requests to the Project Web App (PWA) OData endpoints to fetch the required custom data.

Why is my WBS field missing from the Power Apps gallery?

Standard connectors often omit complex data types or specific structural fields like WBS to maintain optimal performance. You will need to query the PWA data feed through a custom API integration to surface this information in your gallery.
