ME51N/ME52N: Editable customer columns in ALV grid item overview

Hi All,

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!

Kind regards

Silvan
