Adding fields from KOMK structure to screen painter.

Hello Everyone,

i have created an Extra tab(like ADDITIONAL DATA B) using BADI, i have added fields from VBAP table, its working fine. But when i add fields from KOMK structure(KOMK-STCEG) only empty field is showing. Do i need to code something in PBO or PAI?

Thanks & Regards,
