AT SELECTION-SCREEN OUTPUT

if reason1 = <value>

clear: reason2, reason3.

endif.

Hi,

You use the function module 'DYNP_VALUES_UPDATE', here is a code extract showing its use..

*&---------------------------------------------------------------------*
*&      Form  f4_laufd
*&---------------------------------------------------------------------*
form f4_laufd .

  data: ls_laufk type ilaufk,
        lt_laufk type table of ilaufk.

  ls_laufk-laufk = space.
  ls_laufk-sign  = 'I'.
  append ls_laufk to lt_laufk.

  call function 'F4_ZAHLLAUF'
    exporting
      f1typ = 'D'
      f2nme = 'F110V-LAUFI'
    importing
      laufd = p_laufd
      laufi = p_laufi
    tables
      laufk = lt_laufk.

  perform set_selection using 'P_LAUFI' p_laufi.

endform.                                                    " f4_laufd

*&---------------------------------------------------------------------*
*&      Form  set_selection
*&---------------------------------------------------------------------*
form set_selection  using    value(i_field)
                             i_value.

  data: ls_dynpfld type dynpread,
        lt_dynpfld type table of dynpread.

  ls_dynpfld-fieldname  = i_field.
  ls_dynpfld-fieldvalue = i_value.
  append ls_dynpfld to lt_dynpfld.

  call function 'DYNP_VALUES_UPDATE'
    exporting
      dyname     = sy-repid
      dynumb     = sy-dynnr
    tables
      dynpfields = lt_dynpfld.

endform.                    " set_selection

Hi Darren

Somehow the values are not clearing from the selection screen.

here is my code.

DATA: ls_dynpfld TYPE dynpread,

lt_dynpfld TYPE STANDARD TABLE OF dynpread,

lv_repid TYPE sy-repid,

lv_dynnr TYPE sy-dynnr,

lv_initial TYPE string.

lv_repid = sy-cprog.

lv_dynnr = sy-dynnr.

ls_dynpfld-fieldname = 'P_RES2'.

ls_dynpfld-fieldvalue = lv_initial.

APPEND ls_dynpfld TO lt_dynpfld.

CALL FUNCTION 'DYNP_VALUES_UPDATE'

EXPORTING

dyname = lv_repid

dynumb = lv_dynnr

tables

dynpfields = lt_dynpfld

EXCEPTIONS

INVALID_ABAPWORKAREA = 1

INVALID_DYNPROFIELD = 2

INVALID_DYNPRONAME = 3

INVALID_DYNPRONUMMER = 4

INVALID_REQUEST = 5

NO_FIELDDESCRIPTION = 6

UNDEFIND_ERROR = 7

OTHERS = 8.

Hi All,

The issue is resolved.

I used the same FM DYNP_VALUES_UPDATE.

The trick to use it that i had to pass the parameter on which the POV was written alongwith the parameters i wanted to change.

So i had to pass all 3 reason1, reason2 and reason3 to the FM to change the screen values.

Thanks to all.
