3740017 - Multiple same custom partner functions in service contract not all copied to billing document request - SAP S/4HANA Cloud Public Edition

In a service contract item with multiple entries of the same custom partner function only one partner is copied to the subsequent billing document request and invoice.

SAP S/4HANA Cloud Public Edition

1. Create a service contract and add multiple entries of the same custom partner function to the item level.
2. Generate the subsequent billing document request from the service contract.
3. Open the partner data of the billing document request and observe that only one entry of that partner function is present.

This is the standard system behavior. When multiple entries of the same custom partner function exist at item level, only the partner flagged as the main partner is transferred to the subsequent billing document request.
