We are looking an exit/badi to pass default tax code (MWSKZ) in ME21N/22N.
Currently i am doing it with exit EXIT_SAPMM06E_016 and passing value to the dynamic table (SAPLMEPO)POT.
Its working fine in ME21N. But in change mode based on a push button press it should default tax code again.
And at this time, when we press button and dont change any other item fields in PO screen tax code is not updating to database.
I need a proper exit/badi where SAP allows PO Item details to be defaulted and save to database. Thanks in advance.
