RFC Error: User XXX already processing purchase document XXXXXX" in gateway system

437 Views

Hi Experts, need your help for below error in ODATA service.

The locking of purchase order is handled locally in the application. However, middleware receives 'Internal server error' for the ODATA service request. In S4 , session getting killed with error log "RFC Error: User XXX already processing purchase document XXXXXX" in gateway system.

Q1 As locking is handled locally, how can I stop Gateway rejecting any transaction due to any relevant object is locked

Q2 I can see the session was created and the application log is registered, but abandoned due to session was killed.

So the application is partially executed . If the error was handled by standard SAP, how the session gets created ?

Many thanks
