New screen in ME23N with BADI ME_GUI_PO_CUST

Hello to all developers,

I was able to add a new (sub-)screen in the header data ME23N.

All fields are shown.

When I switch the mode to "CHANGE", all fields disappear and of course no tab is shown.

If someone has an idea, please let me know.

Many thanks in advance.
