BBP_PD_PO_GETDETAIL and item relationship issue

Question

Hi all,
I'm working on a a requirement that deals with the distribution phase from SRM of a purchase order.
What I have to do is basically intercept the order, extract its items and the itmlim_rel table in order to get an historical tracking for each position, so that I can "browse" from a certain position of the PO to the corrisponding position of the shopping cart which generated it. This to perform some checks on accounting details wrt the ones retrieved for the corresponding SC items.
Here's a snippet of code (from a custom implementation of the method BBP_B46B_PO_OUTBOUND:
CALL FUNCTION 'BBP_PD_PO_GETDETAIL'
      EXPORTING
        i_guid       = is_header-guid
      TABLES
        e_item       = t_po_item
        e_itmlim_rel = t_po_itmlim_rel.
    READ TABLE t_po_item INTO l_po_item WITH KEY del_ind = ''.
    IF sy-subrc = 0.
      READ TABLE t_po_itmlim_rel
             INTO wa_po_itmlim_rel
             WITH KEY objtype_b = 'BUS2201001'
                      itm_guid_b = l_po_item-guid
                      objtype_a = 'BUS2121001'.     " from PO pos to SC pos
The last READ TABLE ends with sy-subrc = 4, and here's the point. The GUIDs on the relationship table do NOT match the ones on the t_po_item table. How is that possible? There's something I'm missing, hope you gurus can provide me a suggestion or hint

Hi,
Actually,Data is coming in E_Item and PO is getting created  if I comment the code which i have written in BBP_DOC_CHANGE_BADI.As i told you earlier that I am using BBP_DOC_CHANGE_BADI only for value setting in my Custom fields of SRM Portal 7.0.If I uncomment that BADI again I am not getting data in E_Item..I am missing anything in this BADI.
Cann you please check.
I'll give the complete code:
Code in BADI:BBPDOC_CHANGE_BADI._
method IF_EX_BBP_DOC_CHANGE_BADI~BBP_PO_CHANGE.
Checking mode of Purchase Order
    IF  iv_mode EQ gc_c OR   " Create
       iv_mode EQ gc_u OR   " Update
       iv_mode EQ gc_t.     " Check
   ES_HEADER-ZZ_LOGIC = 'X'.
    ES_HEADER-ZZ_LOGIC_DAT = SY-DATUM.
ENDIF.
Code in BADI:BBP_DOC_CHECK BADI
Data : gs_header        TYPE BBP_PDS_PO_HEADER_D,     " PO Header Data
           gt_item          TYPE standard table of  BBP_PDS_PO_ITEM_D,       " Item Data for PO
           gs_item          LIKE LINE OF gt_item,    " Item Data for PO
Checking mode of Purchase Order
    IF iv_mode EQ gc_c OR   " Create
       iv_mode EQ gc_u OR   " Update
       iv_mode EQ gc_t.     " Check
if not iv_doc_guid is initial.
Fetch PO Details
      CALL FUNCTION 'BBP_PD_PO_GETDETAIL'
        EXPORTING
          I_GUID          = iv_doc_guid
          I_WITH_ITEMDATA = gc_x
        IMPORTING
          E_HEADER        = gs_header
        TABLES
          E_ITEM          = gt_item.
