User-exit for changing Field selection Key in Purchase order
We have defined two different ZFK1, ZFK2 Custom Field selection keys for payterms & GR/IR Indicators in Purchase order .
ZFK1 is used across all(most of the ) company codes and document types as defined in config .
But our requiremnt is that ZFK1 must be replaced with ZFK2 for certain compnay code and document types combination dynamically in ABAP without changing the config in SPRO.
Please help me out if any body knows how this can be achieved and what are the user-exits should be used .
Thanks in advance ,
