PL-900 Demonstrate the capabilities of Power Apps Practice Question
A canvas app uses a SharePoint list with a choice column 'Status' (Pending, Approved, Rejected). The app needs to filter the gallery to show only 'Pending' items. The list has 50,000 items. Why does the filter not work as expected?

Correct answer & explanation
✓
The choice column is non-delegable in Power Apps
SharePoint choice columns are non-delegable in Power Apps. When filtering a gallery with a choice column, the filter is applied locally, which fails to return all items when the list exceeds the delegation limit (default 500 items). This explains why filtering for 'Pending' does not work as expected with 50,000 items. Option A is incorrect because the issue is delegation, not the column type itself (choice columns are delegable for some operations but not for filters with '='). Option B is incorrect because the gallery's Items property is set using the Filter function; the problem is that Filter is non-delegable for choice columns. Option D is incorrect because the syntax is not the issue; the formula may be syntactically correct but still fails due to non-delegable filter.
