short dump BAPI_PO_GETDETAIL1

Dear Experts,

Executing transaction ME22N, it displays the smartform, but clicking back button (or any other button) is givin a short dump ' A RAISE statement in the program "CL_HANDLE_MANAGER_MM==========CP" raised the exception condition "FAILURE".

If I delete the call to BAPI_PO_GETDETAIL1, it runs OK.

Anybody knows some other BAPI I can use? Or how to resolve the issue?

Thank you very much for the assistant.
