I’m having an issue with PO change (ME22N) customer function EXIT_SAPMM06E_012.
The very first action I perform after entering the PO in ME22N, I press the check icon
. By the time the customer function is hit, sy-ucomm changes from “MECHECKDOC” TO “ENTE”. That’s bad.


If I press the check icon again, sy-ucomm remains “MECHECKDOC.”. That’s good.


I need to check certain actions in that customer-function and am confused as to why sy-ucomm changes but once.
