I have the following errord code and don't really know what to do even if I try to solve it with the SAP HelpPortal:
"Access Control check validation failed for the Authentication. associated to User P003930 is not matching with AN01720181825-T defined in the Project Cross-Reference.. Suggested Action : Please verify if the Supplier Cross-reference ID in the payload matches with the project Sender Cross-reference configuration. For further assistance, please contact CIG Support with Error Code: CIG-PLT-00639"
Can somebody tell me what to do in detail? Thanks a lot!
