Hi,

Not clear with your requirement...

not only flag...We can compare any variables / work areas / internal tables using IF statement..

Thanks,

flag is used as a mediator,

In the below example records of itab are appended to itab1 except the first record on every change of MATNR , chk how the flag is used

loop at itab.

 at new matnr.
    v_flag = 'X'.
 endat.
 if v_flag eq 'X'.    
  clear flag.
 else.
   append itab to itab1.   
 endif.

endloop.

hi,,

You can use flag for different purposes.Suppose we need to check any of the records being checked for a table you can use flag for that thing .If ther is any changes we can also use flag for that thing also.It depends on different situations.

Hi Silla,

LOOP AT TAB.

IF TAB-FLAG IS INITIAL.

TAB-FLAG = 'X'.

ENDIF.

MODIFY TAB.

ENDLOOP.

TAB-FLAG = 'X'.

MODIFY TAB TRANSPORTING FLAG

WHERE FLAG IS INITIAL.

Rewords if it is helpful.
