ME28 user exit - sy-ucomm not available

Hi experts,

I have a requirement to check sy-ucomm in the user exit EXIT_SAPLEBND_002 which is triggered by transaction ME28 - convert a planned order to purchase requisition. Immediately after pressing the release button for the purchase document the SY-UCOMM value is '%_GC 102 2'.

When the program control reaches the user-exit, SY-UCOMM is already cleared. Analysing the flow shows it is cleared by the method,


CL_GUI_CFW=>DISPATCH. This is totally the ALV way of handling things. The ALV control passes on to call the function module BAPI_PO_RELEASE which inturn calls the user exit.

The question is?? How to get the SY_UCOMM in the user exit. Has any one has ever experienced this before. Your answers are much appreciated.
