IF_EX_ME_PROCESS_PO_CUST ~FIELDSELECTION_ITEM

Hello folks,

i want to check the field LABNR in the tr me21n / me22n.

In case of a special vendor it should not be allowed to be changed - only displayed.

i have the correct methods, the metafiled 74 - Fieldstatus should be '*'

but in debugging sap is not "jumping" to the correct method to get it runnig through my logic. (it looks like everything is activated correct)

in other cases the badi is still "working":

IF_EX_ME_PROCESS_PO_CUST_{PROCESS_ITEM and IF_EX_ME_PROCESS_PO_CUST}PROCESS_SCHEDULE

(the implemented includes in the methods are working pretty well.)

Does somebody knows this problem? It looks like i missed to activate smthg...

thanks for your help in advance!
