Accessing Account assignment in P.Req BADI -PROCESS_REQ_CUST~PROCESS_HEADER

Question

I have implemented a BADI for Purchase requisition and in PROCESS_HEADER method of BADI Implementation for ME_PROCESS_REQ_CUST. I am trying to access account assignment lines on the purchase requisition (EKBN).
IM_HEADER is the only parameter available for me. But I am able to access the items indirectly via get_items method in its interface.
method IF_EX_ME_PROCESS_REQ_CUST~PROCESS_HEADER.
DATA: l_item_list TYPE mmpur_requisition_items,
       l_item_listx type mereq_itemx,
      l_item      TYPE mmpur_requisition_item,
      l_item_akt  TYPE mereq_item,
      l_item_account type MMPUR_ACCOUNTING_LIST,
      l_item_ref  TYPE REF TO if_purchase_requisition_item.
data :  lt_preq_items type standard table of mereq_item .
  FIELD-SYMBOLS:
    <lo_lcl>        TYPE ANY,
    <ls_item>       TYPE mereq_item,
    <ls_itemx>      TYPE mereq_itemx,
    <item>          TYPE mmpur_requisition_item.
  " Get items of purchase requisition
   l_item_list = im_header->get_items( ).
  check IM_COUNT <= 1 .
* Logic for approver determination goes here .
   LOOP AT l_item_list ASSIGNING <item>.
    l_item_akt = <item>-item->get_data( ).
    break-point.
*   l_item_account = <item>-item->get_items( ).
    append l_item_akt to lt_preq_items[].
  ENDLOOP.
I am able to collect all the items of the p.req (i.e EBAN entries) in lt_preq_items .
Now, my challege is to use get_items() method inside
IF_ACCT_CONTAINER_MM~GET_ITEMS   (  Return Account Assignment Objects ) which is inside IF_PURCHASE_REQUISITION_ITEM interface.
A simple  l_item_account = <item>-item->get_items( ) resulted in syntax error. How can I get account assignment objects inside this process header BADI of purchase requisition ? Any useful tips is greatly appreciated.

Shareen

Hi,
DATA: l_item_list TYPE mmpur_requisition_items,
       l_item_listx type mereq_itemx,
      l_item      TYPE mmpur_requisition_item,
      l_item_akt  TYPE mereq_item,
      l_item_account type MMPUR_ACCOUNTING_LIST,
      l_item_ref  TYPE REF TO if_purchase_requisition_item.
data :  lt_preq_items type standard table of mereq_item .
  FIELD-SYMBOLS:
    <lo_lcl>        TYPE ANY,
    <ls_item>       TYPE mereq_item,
    <ls_itemx>      TYPE mereq_itemx,
    <item>          TYPE mmpur_requisition_item.
  " Get items of purchase requisition
   l_item_list = im_header->get_items( ).
  check IM_COUNT <= 1 .
Logic for approver determination goes here .
   LOOP AT l_item_list ASSIGNING <item>.
    l_item_akt = <item>-item->get_data( ).
    break-point.
  *litem_account = <item>-item->IF_ACCT_CONTAINER_MM~GET_ITEMS( ).*_    
append l_item_akt to lt_preq_items[].
  ENDLOOP.
Check with the above code for l_item_account .
