How to write dynamic where condition in loop ?

[vinayad]

Is it possible to achieve this ?

field-symbols : <i_itab> TYPE table ,

<wa_tab> type any.

Loop at <i_itab> assigning <wa_tab> where (dynamic condition).

I am trying to replace value, if the condition satisfies it will change but i am unable to satisfy the condition here.

- thank you !

Hello vinayad,

Could you put in some more information about how your dynamic condition will be formed?

ABAP documentation - LOOP AT ... WHERE (cond_syntax) (dynamic)

Hi Sandra Rossi

When I tried this below way,

DATA dref TYPE REF TO i.

DATA :BEGIN OF line,
col1 TYPE i,
col2 TYPE i,
END OF line.

dref = REF #( num ).

LOOP at <i_itab> INTO line FROM 10 TO 25 WHERE col2 > dref->*.

I am getting error, The field REF is unknown.

It's a completely different question. "dref = REF #( num )" works only from ABAP 7.40 SP 2.

Kindly try with range. Declare data type as range and then loop that dyanmic query into work area.

where is the condition?

Hi Tamit Kumar Das Sharma

data cond type string.

Loop at <i_itab> assigning <wa_tab> where (cond).

-Thanks.

Hi,

CASE gv_cdvue.
  WHEN 'L'.
    lv_condi = 'dcmdr GE gv_daybf   OR dcmdr LE gv_daybf   '.
  WHEN 'C'.
    lv_condi = 'dcldr GE gv_daybf   OR dcldr LE gv_daybf   '.
  WHEN 'E'.
  WHEN OTHERS.


ENDCASE.


  LOOP AT gt_plcad INTO ls_plcad  WHERE (lv_condi).
    ....
  ENDLOOP.
