Error status on validating PO Item tcode ME22N is always displayed at last

Question

Hi Gurus,
I am using the method  IF_EX_ME_PROCESS_PO_CUST~CHECK to validate a line item.
I have say 20 line items and the 5th line item has an error on validating.
I am able to display the correct error message with correct line item number,
however in the status column, the red block is shown only in the last item and not in the 5th line item.
Please suggest how to get this red block indicator of error in the erroneous line item.
I have already searched the forum but could not get any relevant solution.
Below is the example of my code.
LS_HEADER = IM_HEADER->GET_DATA( ).
        LS_ITEM = IM_HEADER->GET_ITEMS( ).
        LOOP AT LS_ITEM INTO LINE_ITEM.
          PO_ITEM = LINE_ITEM-ITEM->GET_DATA( ).
          SELECT SINGLE NETPR FROM EKPO INTO L_NETPR
                        WHERE EBELN = LS_HEADER-EBELN
                        AND EBELP = PO_ITEM-EBELP.
          IF L_NETPR <> PO_ITEM-NETPR.
     L_EBELP = PO_ITEM-EBELP.
             SELECT * FROM EKBE INTO CORRESPONDING FIELDS OF TABLE I_EKBE1
               WHERE EBELN = LS_HEADER-EBELN
               AND   EBELP = L_EBELP
               AND   BWART = '101'.
        DESCRIBE TABLE I_EKBE1 LINES LIN1.
        SELECT * FROM EKBE INTO CORRESPONDING FIELDS OF TABLE I_EKBE2
                  WHERE EBELN = LS_HEADER-EBELN
                  AND   EBELP = L_EBELP
                  AND   BWART = '102'.
        DESCRIBE TABLE I_EKBE2 LINES LIN2.
        IF LIN1 > LIN2.
          CONCATENATE 'No price change possible as GRN exists for PO' LS_HEADER-EBELN  'AND item' L_EBELP into g_msg SEPARATED BY space.
           MESSAGE g_msg TYPE 'E'.
          CH_FAILED = 'X'.
        ENDIF.
          ENDIF.
        ENDLOOP.

Hello,
then we need to do another way to collect message rather flushing in task bar
rather than statement message, call method 
call method cl_message_mm=>create
it has message parameters, please pass require value
this method collect messages in message collector...
after that call method 
CALL METHOD im_item->invalidate( )
Please try and let me know your feedback
Thanks
