Thanks a lot Vinod!! It's was helpful.
I have coded to retrieve the item data as well. Please see the below code .
METHOD IF_EX_ME_PROCESS_REQ_CUST~PROCESS_ITEM.
TYPES : BEGIN OF TY_EBAN_EBKN,
           BANFN          TYPE EBKN-BANFN,
           BNFPO          TYPE EBKN-BNFPO,
           WBS_ELMNT      TYPE ZPS_BOQ-WBS_ELMNT,
           MAT_CODE       TYPE EBAN-MATNR,
           MENGE          TYPE EBAN-MENGE,
         END OF TY_EBAN_EBKN.
  DATA:LT_ITEMS TYPE MMPUR_ACCOUNTING_LIST,
        LS_ITEM TYPE MMPUR_ACCOUNTING_TYPE,
        LS_ITEM_DATA_WBS TYPE EXKN,
        LS_ITEM_DATA_WBS1 TYPE EXKN,
        LT_ITEM_DATA_MAT TYPE TABLE OF MEREQ_ITEM,
        LT_ITEM_DATA_WBS TYPE TABLE OF EXKN,
        LT_ITEM_DATA_WBS1 TYPE TABLE OF EXKN.
LT_ITEMS =  IM_ITEM->IF_ACCT_CONTAINER_MM~GET_ITEMS( ).
LOOP AT LT_ITEMS INTO LS_ITEM.
    CLEAR LS_ITEM_DATA_WBS.
    LS_ITEM_DATA_WBS = LS_ITEM-MODEL->GET_EXKN( ).
    APPEND LS_ITEM_DATA_WBS TO LT_ITEM_DATA_WBS.
    CLEAR LS_ITEM_DATA_WBS.
  ENDLOOP.
ENDMETHOD.
I am facing one problem here. I am getting only one record in LT_ITEM_DATA_WBS internal table although there are 2 line items at item level.  Actually what I want to exactly is, I want to combine the Material and WBS element in one internal table.
Can you please help me out how can i proceed with that and let me know if you need any further relevant info.
Cheers
