Gyz,
I have a strange problem. I need to do some modifcation to the PO. The PO gets the net price from the Agreement line no. This value will be error for some material category. I need to place a 0 in the net price value field after the user clicks on the save button for these mat. category.. Currently the error is displayed only after the user clicks the save. I tried the exits MM06E004 and MM06E005. The control does not go to any of the functions in these exist after i click on save. The BADI's ME_PROCESS_PO_CUST and ME_GUI_PO_CUST does not exist in SAP 4.6C.
Please let me know your suggestions or other alternatives.
Points assured to all replies.
Madan..
