Badi ME_PROCESS_REQ_CUST Method SET_DATA not updating table

Hi Experts,

I am facing difficulty while trying to change BLCKD value on Purchase Requisition creation/change. In debugger value is getting changed but database table is not updating.

I have checked much thread but not found anything suitable.

Please help me on this.

Below code is written on the methods PROCESS_ITEM, POST and CHECK.

------------------------------------------------------------------

DATA: I_ITEMS TYPE MMPUR_REQUISITION_ITEMS,
        WA_ITEM LIKE LINE OF I_ITEMS,
        LV_IF_ITEM TYPE REF TO IF_PURCHASE_REQUISITION_ITEM,
        LT_ITM_DATA TYPE MEREQ_ITEM,
        LX_ITM_DATA TYPE MEREQ_ITEMX.

  CALL METHOD IM_HEADER->GET_ITEMS
    RECEIVING
      RE_ITEMS = I_ITEMS.


  LOOP AT I_ITEMS INTO WA_ITEM.

      LV_IF_ITEM = WA_ITEM-ITEM.

      CALL METHOD LV_IF_ITEM->GET_DATA
        RECEIVING
          RE_DATA = LT_ITM_DATA.

      CALL METHOD LV_IF_ITEM->GET_DATAX
        RECEIVING
          RE_DATAX = LX_ITM_DATA.

      IF LT_ITM_DATA-FRGGR IS INITIAL. " If release code is not available

        LX_ITM_DATA-BLCKD = 'X'.

        CALL METHOD LV_IF_ITEM->SET_DATAX
          EXPORTING
            IM_DATAX = LX_ITM_DATA.

        LT_ITM_DATA-BLCKD = '1'.

        CALL METHOD LV_IF_ITEM->SET_DATA
          EXPORTING
            IM_DATA = LT_ITM_DATA.

    ENDIF.
  ENDLOOP.
