Delegation in Power Apps means sending data processing tasks to the data source instead of processing the data inside the app. When delegation works, the data source (such as SharePoint, Dataverse, or SQL Server) performs filtering, sorting, or searching and returns only the required records.
When delegation works:
- The data source processes the query
- Only required records are returned so app performance improves
Benefits include:
- Correct results even with thousands of records
- Faster loading time and lower memory usage
Example: If a list contains 20,000 records, a delegable filter like
Filter(Employees, Department="HR")
allows the server to return only HR records.
Without delegation, Power Apps evaluates only the first 500 or 2000 records, which can lead to incomplete results.
