user exit for me22n to make field NETPR not to be editable

[Mahesh1]

Hi all,

Once advance payment is made against PO, again system should not allow for amendments.

Here I want to change the field NETPR to not to be editable of transaction me22n if EKBE-VGABE = 4 ( transaction event type = down payment)

how this can be done? Do I need to use any User exit? please suggest.

Hi,

Can you try it in BADI-> ME_PROCESS_PO_CUST -> PROCESS_ITEM

OR

ME_PROCESS_PO_CUST -> FIELDSELECTION_ITEM.
