Internal Table

[Former Member]

Hi

I have appended 5 lines data in an internal table.

Now while appending 6th line, i want to do a validation.

If it fails, i have to delete those 5 lines.

How to do this..???

Can anyone give me the syntax..??

You need to have condition for deletion. Else you will have to loop and delete.

LOOP AT ITAB.

IF SY-TABIX > 6.

DELETE ITAB.

ENDIF.

ENDLOOP.

Before the append statement

IF a = b.

APPEND 6TH LINE.

ELSE.

DELETE ITAB.

ENDIF.

One correction.

IF a = b.
APPEND 6TH LINE.
ELSE. 
<b>refresh</b> ITAB.
ENDIF.

There is nothing wrong in using DELETE as well.

Hi,

data : l_flag type c.

Loop at itab into wa_tab.

if sy-tabix = 11.

• Do the validation here

l_flag = `X`.

exit.

endif.

Endloop.

if l_flag = `X`.

delete itab from 6 to 11.

endif.

Best regards,

Hello Pavan

Why don't you add a "marker" field to your internal itab?

All the itab entries that you possibly want to delete after a certain validation failed have field MARK = 'X'.

As soon as your validating entry is coming you add coding like this:

IF ( <validation> = 'X' ).  " 'X' = is valid, keep entries
  CLEAR: gs_entry-mark.
  MODIFY itab FROM gs_entry
    TRANSPORTING mark
    WHERE ( mark IS NOT INITIAL ).
ELSE.
  DELETE itab where ( mark = 'X' ).
ENDIF.

This solution is somewhat more flexible because you do not have to count lines and store indexes. Perhaps your validation is based on a certain combination of field values in an entry. Then this solution would be more suitable.
