I have requirement to update the contract with additional partners ( OA-Orderding address, PI- Invoicing address) at the header level . I am using the BAPI 'BAPI_CONTRACT_CHANGE' to achieve the same. But I am getting an error 'Please enter a valid partner role'. ( Eventhough I am entering valid partners roles)
If anybody has worked on this BAPI for updating partners,Please let me know.
