Implementing BADI ME_PROCESS_PO_CUST ??
I want to implement BADI ME_PROCESS_PO_CUST to Z_ME_PROCESS_PO_CUST. Under this I need to use method CHECK to validate the header Level EKGRP (Purchasing Group) with the Info Record item Level EKGRP (Purchasing Group). If both are different, then I need to throw message with setting parameter CH_FAILED = 'X'.
Now my question is I can get the header level EKGRP by IMPORTING parameter IM_HEADER (IF_PURCHASE_ORDER_MM) has a method GET_DATA which returns the header data (structure MEPOHEADER). But to get the Item level info records EKGRP I will call method IM_HEADER->GET_ITEMS to retrieve PO item level data. Can you please tell me how to get the info record data from there and how to go ahead further??
