How to connect Multi Tenant connection in different domain fabric to synapse data pull

[NewUser2025]

I need to connect fabric data warehouse from one domain to different domain with service principle using Azure synapse, I need to copy data from fabric data warehouse to sql database, I need proper steps to give what are the required permissions for service principle and I need required permissions in fabric workspace.
We already created one service principle in Domain-1 Azure (XYZ.123@xyz.com) and we are trying to connect in fabric workspace  with Domain-2 Fabric (abc.123@abc.com) using service principle, we are trying to give fabric workspace access to azure service principle (Domain1) but We are unable to see or connect azure service principle

In your case the problem is that the service principal was created in Domain-1 AAD, while the Microsoft Fabric environment belongs to Domain-2 AAD. Fabric can only see service principals that exist in its own tenant, so the Domain-1 service principal must first be registered as an Enterprise Application in Domain-2. Once you do that, Fabric in Domain-2 will be able to recognise and grant permissions to it.

The sequence is as follows:

in Domain-2 AAD, create an Enterprise Application using the client ID of the Domain-1 service principal, then in the Fabric Admin portal make sure that service principal access is enabled, and finally add the service principal as a member of the Fabric workspace with an appropriate role such as Contributor or Viewer. Inside the Fabric data warehouse, create a SQL user for the service principal from external provider and assign it to db\datareader or db\_datawriter roles depending on whether you need read or write.

After these steps, in Synapse you can configure a linked service to the Fabric SQL endpoint using the same service principal credentials and copy data into SQL Database. The key missing piece in your setup is that the Domain-1 service principal must be explicitly brought into Domain-2 as an Enterprise Application before it can be assigned permissions in Fabric.
