Hi,

Help needed to remove this delete from within the loop.

{code

Loop at itab where <condition>.

delete itab index sy-tabix.

Exit.

Endloop.

{code}

The functionality of the code should not be affected.

Useful help would be awarded

hi,

do this way ... take a new field(Flag) in the itab ...


Loop at itab where <condition>.
 lv_tabix = sy-tabix. 
<statements>
 if <conditions> 
  itab-flag = 'X'.
  modify itab index lv_tabix transporting flag.
  Exit.
 endif. 
Endloop.

delete itab where flag = 'X'.

I don't know what <statements> you are using, but the easiest way to do this, is this:

delete itab where <conditions>.

Hi,

Never delete an internal table inside the same loop.

Rather add a flag field in the table.

In the loop at itab..mark the field = 'X 'where u want to delete.

and at the end of loop,

DELETE ITAB WHERE FLAG = 'X'

Please assign points if helpful

Delete inside loop is not required.

You can use directly the statement

DELETE itab WHERE logexp.

DELETE TABLE itab WITH TABLE KEY k1 = v1 ... kn = vn.

Hi,

Instead of deleting data from itab use another internal table of same type (itab1) and append it. Use itab1 data for further processing.

check below logic...

{code

Loop at itab1 into wa_itab1 where <condition>.

if <condition>

append wa_itab1 to itab2.

exit.

endif.

Endloop.

refresh itab1.

itab1[] = itab2[].

{code}
