Dyamic Loop

Former Member — Mon, 27 Nov 2006 19:00:59 GMT

Hi guys,

I have two dynamic tables <it_pro> and <it_acor>, and I need to make a loop statement for one of then depending on the column of an ALV that was edited.

How can I do in order to do a loop dynamically?

Regards,

Eric

HI,

Why don't you use the DO loop, then write an EXIT command where ever required

Hi Sudheer,

Why I want to do is to use the same loop for the two validations in order to save lines of code.

For example,

IF ls_mod_cell-fieldname = 'PROPUESTA'.

I want to make this: LOOP AT <it_pro> INTO <wa_pro>.

else

LOOP AT <it_acor> INTO <wa_pro>.

endif.

I want to make it like this because all the code inside the loop is the same.

Regards,

Eric

Hello Eric

Perhaps you are looking for something like this:

field-symbols:
  <lt_itab>       TYPE TABLE,
  <ls_line>       TYPE ANY,
  <ld_fld>         TYPE ANY.


  IF ( ls_mod_cell-fieldname = 'PROPUESTA' ).
    ASSIGN <lt_itab> TO <it_pro>.
  ELSE.
    ASSIGN <lt_itab> TO <it_acor>.
  ENDIF.

  LOOP AT <lt_Itab> ASSIGNING <ls_line>.
    ASSIGN ls_mod_cell-fieldname OF STRUCTURE <ls_line> TO <ld_fld>.

*   Now validate the changed data...
    IF ( <ld_fld> .... ).

    ELSE.

    ENDIF.
  ENDLOOP.

Regards

Uwe

Thanks again Uwe,

This was what I needed.

field-symbols:

<lt_itab> TYPE TABLE,

<ls_line> TYPE ANY,

<ld_fld> TYPE ANY.

IF ( ls_mod_cell-fieldname = 'PROPUESTA' ).

ASSIGN <it_pro>< TO lt_itab>.

ELSE.

ASSIGN <it_acor>< TO lt_itab>.

ENDIF.

LOOP AT <lt_Itab> ASSIGNING <ls_line>.

....

Regards,

Eric

You can try these code below:


IF ( ls_mod_cell-fieldname = 'PROPUESTA' ).
  itab_name = 'it_pro'.
ELSE.
  itab_name = 'it_acor'.
ENDIF.

LOOP AT (itab_name) ASSIGNING <ls_line>.
....

If it can run correctly, it wil be high performance.

Sorry, unable to interpret the expression "(itab_name)".

It is error.
