MB90 related problem

Hi all,

i have a need to stop printing my smartform, according to the criteria that for a particular Ref. Doc., i have to see the list of Material Document.

If the last value of Material Document have a movement type "102", then it wouldn't get printed.

I have written this code but not getting desired result, please anyone correct my code(after seeing the screenshot).

DATA : ls_mseg type mseg,

        it_mseg type mseg,

        it_mseg1 type mseg,

        it_mseg2 type mseg.

LOOP AT RG_MBLNR.

clear: ls_mseg.

select single * from mseg into ls_mseg

   where mblnr in RG_MBLNR.

select single lfbnr from mseg into it_mseg where lfbnr = mseg-belnr.

select * from mseg into it_mseg1 where lfbnr = mseg-lfbnr.

select max( belnr ) from mseg into it_mseg2 where belnr = RG_MBLNR.

ENDSELECT.      

   IF sy-subrc eq 0.

     DELETE RG_MBLNR.

   ENDIF.

ENDLOOP.
