In purchase requisition ME51N-ME53N I added a customer tab with customer fields. But they are outputed every time in ALV grid item overview in display mode.
Hence my question is how I can make them editable for tcodes ME51N/ME52N?
The customer tab I implemented with the User-Exit enhancement MEREQ001. In the forum I found that I have to use for handling the fields in the ALV grid the BADI ME_PROCESS_REQ_CUST.
Can anyone give me a working example?
Thank you very much in advance for your support!
