I have created and activated the implementation Z_LINE_ITEMS_GET_GKONT of the BAdI LINE_ITEMS_GET_GKONT for T. FAGLL03, for adding nell' output ALV list, two fields: GKART and GKONT, using CALL FUNCTION 'GET_GKONT'.
After implementation, the fields GKART and GKONT appear in the box "Displayed fields" of the standard layout and all olds customs layouts, of the T. FAGLL03, where you do not need.
I would that, initially, the fields GKART and GKONT are in the box "Hidden fields", to avoid changing the olds customs layouts. Is possible?
Thanks,
Mio
