When You are using BAPI_SALESORDER_CHANGE You need to fulfil table order_item_in and then change value and mark this change (X for field which You are changing) and update flag in table order_item_inx. Also You need to set update flag in the header.

Example code of changing rejection reason (in Your case You need to do analogic changes for MATNR

ORDER_HEADER_INX-UPDATEFLAG = "U"

ORDER_ITEM_IN- ITM_NUMBER = "000010".

ORDER_ITEM_IN-MATERIAL = material_number

ORDER_ITEM_INX-ITM_NUMBER = "000010"..

ORDER_ITEM_INX-UPDATEFLAG = "U".

ORDER_ITEM_INX-MATERIAL = "X".)

SELECT * FROM vbap INTO TABLE @DATA(lt_vbap_delv)
        WHERE vbeln = '100000002'
        AND abgru = ''
        AND uepos = '000000'
        AND ( LFGSA = 'A' OR LFGSA = 'B' ). 

         LOOP AT lt_vbap_delv INTO DATA(ls_vbap_delv).

          APPEND INITIAL LINE TO order_item_in ASSIGNING FIELD-SYMBOL(<it_in_dlv>).
          <it_in_dlv>-itm_number = ls_vbap_delv-posnr.
          <it_in_dlv>-reason_rej  = 'Z1'.

          APPEND INITIAL LINE TO order_item_inx ASSIGNING FIELD-SYMBOL(<it_in_dlvx>).
          <it_in_dlvx>-itm_number =  <it_in_dlv>-itm_number.
          <it_in_dlvx>-reason_rej = 'X'.
          <it_in_dlvx>-updateflag = 'U'.

        ENDLOOP.

order_header_inx-updateflag = 'U'.

          CALL FUNCTION 'BAPI_SALESORDER_CHANGE'
