I have a custom tab in ME22N / ME23N where I have all custom fields. I used badi ME_PROCESS_PO_CUST to update values of custom fields, same is working fine. problem is there are some custom fields which need to display description of the fields as well. I have taken I/O field in screen for those fields.
In the code I am passing values to screen elements for descriptions, but once I come out of method those values are clearing off and descriptions not appearing in ME22N.
I tried EXIT_SAPMM06E_006 and EXIT_SAPMM07. but not worked. problem is description custom fields are not added in EKKO table. user accepting to do some programming at screen level to display them.
Please give your inputs how to solve the same.
