lock/disable PO standard fields in me22n
I have a request from user that is:
In ME22N (PO Change) based on certain criteria they want me to lock/disable almost all of the fields for editing in the PO with the exception of a few fields like Qty. Is there a user exit of some sort that will allow me to do this. I have been poking around in here and have come up empty. I know there is a BADI that allows you to change custom fields that you create for the PO but havent seen anything for SAP standard fields.
