     --> Error: Properties InternalID and InternalID1 under entity BusinessPartnerRelationship have duplicate UI Text ID

The issue occurred because the fields InternalID and InternalID1 in the BusinessPartnerRelationship OData service were assigned the same UI text label, causing a duplicate label conflict during activation.

1. Open the custom OData service in Admin → OData Service Explorer.
2. In the field list, select InternalID under FirstBusinessPartner.
3. In the Properties panel on the right, change the UI Text Label from "ID" to a unique value (e.g., FirstPartnerID).
4. Repeat the same steps for InternalID1 under SecondBusinessPartner, assigning a different unique label (e.g., SecondPartnerID).
5. Save the changes and activate the service.

After assigning unique UI text labels to both fields, the duplicate label conflict was resolved.
