Pack HU - Pack Carton Hus to Pallet HUs- BAPI Issue

[former_member300568]

Hi All,

I have a scenario where i have to generate Pallet HU and then attach it to delivery. Next step would be to Pack Carton HU to Pallet HU.

First step, i am able to create HU successfully with below Code, after commit i see the HU Number in VEKP table.

But When i try to link it to delivery i dont see any error from BAPI but i am unable to see the vbeln_ga in VEKP.

  
        CALL FUNCTION 'BAPI_HU_CREATE'
          EXPORTING
            headerproposal = ls_headerproposal
          IMPORTING
            hukey          = ls_hukey
            huheader       = ls_hu_header
          TABLES
            itemsproposal  = lt_item_proposal
*           ITEMSSERIALNO  =
            return         = lt_return
*           HUITEM         =
          .
*Commit HU creation,then assign HU to shipment
        CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
          EXPORTING
            wait = c_x.

        REFRESH lt_return.

        ls_hu_header-pack_mat_obj_key = gv_delv.
        ls_hu_header-pack_mat_object = '12'.
        CALL FUNCTION 'BAPI_HU_CHANGE_HEADER'
          EXPORTING
            hukey     = ls_hukey
            huchanged = ls_hu_header
* IMPORTING
*           HUHEADER  =
          TABLES
            return    = lt_return.

        CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'.

To pack HU i tried SD_DELIVERY_UPDATE_PACKING , But it didnt work. But when i try 
CALL FUNCTION 'BAPI_HU_PACK'
    EXPORTING
      hukey        = lv_hukey
      itemproposal = lk_itmproposal
    IMPORTING
      huitem       = lk_huitem
      huheader     = lk_huheader
    TABLES
      return       = gt_return.

I do not get error , but in VEPO table i dont see the Carton HU which i am passing to the itmproposal above is 
not linked to the parent (pallet) HU.
Any suggestions will be appreciated
