What’s happening?
Customers encounter an error when attempting to save a subnet for Power Platform integration, specifically: "Failed to save subnet '[...]'. Error: 'Subnet requires any of the following delegation(s) [Microsoft.PowerPlatform/enterprisePolicies] to reference service association link.'"


Reason:
This arises due to the absence of the required subnet delegation for the Power Platform service association link. This can occur if the virtual network (VNet) is not configured correctly, particularly if it does not include a VNet from the appropriate Azure region as specified in the documentation.


Resolution:

  1. Ensure that the VNet includes subnets from two different Azure regions as per the guidelines in the Power Platform documentation Set up Virtual Network support for Power Platform - Power Platform | Microsoft Learn.
  2. Validate the connection using the steps outlined in the Microsoft documentation: Validate the Connection.
  3. Check the DNS configuration on the container to ensure it is set up correctly and that DNS resolutions are functioning as expected.
  4. If the error persists, verify that the subnet is correctly delegated to the Power Platform service by checking the service association links and ensuring that the necessary permissions and configurations are in place.
