I create a new tab in MSC*N, and extend it in BADI ES_BATCH_MASTER.
refer to sample class CL_EX_VB_BM_ADD_SCREEN_FIELDS, I extend in AFTER_CUSTOM_SCREEN_PAI & BEFORE_CUSTOM_SUBSCREEN_PBO, but can't save addon fields into MCHA.
BEFORE_CUSTOM_SUBSCREEN_PBO：gs_mcha = is_mcha.
AFTER_CUSTOM_SCREEN_PAI：es_mcha = gs_mcha.
I only extend MCHA in system by APPEND.
My question is that does it necessary to extend MCH1 also?
