Custom idoc giving error

Question

hi friends
i am adding two segments in Purchase orders ORDERS ---/ afs/orders05
i found the exit and implemented the logic, but when i triggered the idoc
i noticed that custom segment is coming after every segment
like e1edk01 ---
     ze1edka1 --- (repeating)
     e1edkb1 ---
    ze1edka1 -
(repeating)
how to make changes in code so that it will come in right way (means it should not repeated)
thanks
Anil

Hello Anilkumar
I assume you want to add your custom segments just behind some standard segments.
Probably your logic looks like this:
DATA: ls_edidd   TYPE edidd.
DATA: ld_idx       TYPE i.
LOOP AT int_edidd INTO ls_edidd
                             WHERE ( segnam = '<name of standard segement>' ).
  ld_idx = syst-tabix + 1.
" Add custom segment
  ls_edidd-segnam = '<name of custom segment>'.
  ls_edidd-sdata = ... .
  INSERT ls_edidd INTO TABLE int_edidd INDEX ld_idx.
ENDLOOP.
If the default segment is repeated the custom segement will be repeated as well. Therefore, add a counter logic:
  LOOP AT int_edidd TRANSPORTING NO FIELDS
            WHERE ( segnam = '<name of custom segment>' ).
    EXIT.
  ENDLOOP.
  CHECK ( syst-subrc NE 0 ).
" NOTE: if customer segment already found leave exit, ELSE...
DATA: ls_edidd   TYPE edidd.
DATA: ld_idx       TYPE i.
LOOP AT int_edidd INTO ls_edidd
                             WHERE ( segnam = '<name of standard segement>' ).
  ld_idx = syst-tabix + 1.
