Hi,

Function module will decrease with performance of your program because Function group will be loaded into your program's memory at runtime.

Try these codes:

Hi Sri,

First create a search-help for the second field(location) and this Search help use Plant field as a Import parameter and location as Export Parameter.

This way you will get the Location according the plant .

Thanks

let me tell u clearly..

for the plant i mentioned it as p_werks type t001w-werks.(f4 comes default without any coding)

data:g_lgort type lgort_d.

for location select-options: s_lgort for g_lgort no-extension no intervals.

now i had selected a plant 1100 in the screen.

then f4 should come for the location only for the plant 1100.

now how should i read it while selecting location data from too1L?..

Hi, Sri.

Please Test the following Sample Code. I have test and it is working fine as your requirement,

TABLES: t001w, t001l.

SELECT-OPTIONS p_werks FOR t001w-werks NO-EXTENSION NO INTERVALS.
SELECT-OPTIONS g_lgort FOR t001l-lgort NO-EXTENSION NO INTERVALS.

DATA: i_return TYPE ddshretval OCCURS 0 WITH HEADER LINE,
      c TYPE c VALUE 'S'.

* Search Help for LGORT
AT SELECTION-SCREEN ON VALUE-REQUEST FOR g_lgort-low.

  TYPES: BEGIN OF t_lgort,
    lgort LIKE t001l-lgort,
  END OF t_lgort.

  DATA: it_lgort TYPE STANDARD TABLE OF t_lgort WITH HEADER LINE.

  SELECT DISTINCT lgort
    INTO CORRESPONDING FIELDS OF TABLE it_lgort
    FROM t001l
    WHERE werks = p_werks-low.

  SORT it_lgort BY lgort.

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      retfield    = 'P_WERKS'
      dynpprog    = sy-repid
      dynpnr      = sy-dynnr
      dynprofield = 'P_WERKS'
      value_org   = c
    TABLES
      value_tab   = it_lgort
      return_tab  = i_return.

and one thing more don't forget to Press the enter Button after enter the Plant.

Please Reply if any Issue.

Kind Regards,

Faisal
