Hi,
You have to modify the value in the user exit.
Write this type of code inside the include ZXM06U43 . I have given you the sample code, make use of the bold part, you need to modify the POT table and modify the internal table for your logic.
DATA v_cnt TYPE i.                                
DATA char(50) VALUE '(SAPLMEPO)POT[]'.
DATA: i_ind TYPE TABLE OF bekpo,
      wa_ind LIKE LINE OF i_ind.
create/change purchase order
IF sy-tcode EQ 'ME21' OR sy-tcode EQ 'ME22' OR
   sy-tcode EQ 'ME21N' OR sy-tcode EQ 'ME22N' OR
   sy-tcode EQ 'ME23' OR sy-tcode EQ 'ME23N'.    
    CLEAR wa_ind.
    FIELD-SYMBOLS <f1> TYPE ANY.
Move memory of internal table POT to field symbol f1.
    ASSIGN (char) TO <f1>.
Move content of f1 to internal table i_ind
    i_ind[] = <f1> .
    LOOP AT i_ind INTO wa_ind.
      IF wa_ind-pstyp = '9'.            " Service PO - item category
IF PO Line item has History per Purchasing Document as 'D'
Set indicators on, for the line item.
        CLEAR v_cnt.
        SELECT COUNT( * ) INTO v_cnt FROM ent5100
                                     WHERE ebeln = wa_ind-ebeln
                                       AND ebelp = wa_ind-ebelp
                                       AND bewtp = 'D'.
        IF sy-subrc = 0.
          wa_ind-wepos = 'X'.            " Set Goods Receipt Indicator
          wa_ind-webre = 'X'.            " Set GR-based IV Indicator
          wa_ind-lebre = 'X'.            " Set Srv-based IV Indicator
        ELSE.
          wa_ind-wepos = ' '.            " Clear Goods Receipt Indicator
          wa_ind-webre = ' '.            " Clear GR-based IV Indicator
          wa_ind-lebre = ' '.            " Clear Srv-based IV Indicator
          wa_ind-xersy = ' '.            " Clear ERS Indicator
        ENDIF.                                             
        MODIFY i_ind FROM wa_ind INDEX sy-tabix.
      ENDIF.
    ENDLOOP.
    <f1> = i_ind[].
ENDIF.
Hope this helps.
Thanks,
Senthil
