Need your advice on populating user name while posting from PAPM via standard RFA.
We are trying to post data from standard RFA FI -GL Items to S/4 . The field Username is mapped to a formula = CURRENT_USER in Input to RFA function.
In S/4 documents are getting posted with username = 'NXI_USER' and not with user id of person who is executing the standard RFA function. We tried formula SESSION_USER also It is giving same results.
Could you please help with this .Our requirement is to post the SAP user ID of person who is executing the activity/function.
