We are facing issue with custom exit handler class for CL_MDG_BS_BP_HANDLER--> custom class does not update changed address for customer in KNA1 & ADRC and changed address gets updated only for business partner. For customer it copies old BP address from memory. There is no issue with CVI , as after removing custom exit handler class from view V_MDG_BS_BP_HDL , customer address gets updated with latest address from MDG CR.
We have implemented multiple methods --> read_object_data/map_data_to_api/map_data_to_staging/save additional object data,etc., methods in custom handler class. Is there anything missing because of which it copies old bp data to customer?
