Input parameter is not save after selection. Please help!

[Former Member]

Hi all,

I am writing a report that read two inputs parameters. These are obligatory.

SELECTION-SCREEN BEGIN OF BLOCK 1 WITH FRAME TITLE text-005.

PARAMETERS:   name(40) type c OBLIGATORY.

PARAMETERS:   nr type i OBLIGATORY.

SELECTION-SCREEN END OF BLOCK 1.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR name.

............

Perfom XXXX.

Perform YYY.

What am I doing wrong?

I can select the first parameter from the help list without problem. When I enter the second one, I can see that the variable is empty after setting a break point and going in the debug mode.

What should I do to make this work? Please help.

Hi Maria Margy,

I tried like this,  I am getting values can you share your code to check what's the problem.

DATA       : r_name TYPE TABLE OF ddshretval WITH HEADER LINE.
DATA       : BEGIN   OF   t_name OCCURS 0,
              name   TYPE char40,
              END     OF   t_name.

SELECTION-SCREEN BEGIN OF BLOCK 1 WITH FRAME TITLE text-005.
PARAMETERS:   name(40) type c OBLIGATORY.
PARAMETERS:   nr type i OBLIGATORY.
SELECTION-SCREEN END OF BLOCK 1.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR name.
  REFRESH t_name.
   APPEND 'Ramesh' TO t_name.
   APPEND 'Ganesh' TO t_name.

   CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
     EXPORTING
       retfield        = 'NAME'
       dynpprog        = sy-repid
       dynpnr          = '1000'
       dynprofield     = 'name'
       window_title    = 'Name'
       value_org       = 'S'
     TABLES
       value_tab       = t_name[]
       RETURN_TAB      = r_name[]
     EXCEPTIONS
       parameter_error = 1
       no_values_found = 2
       OTHERS          = 3.
   IF sy-subrc <> 0.
   ENDIF.

start-of-SELECTION.

Write :/ name, nr.

Thanks for your answer. Is it possible to define an intervall for the parameter

PARAMETERS:   nr type i OBLIGATORY.

I would like that only number for example between 0 and 1000 can be enter by the user.

Thanks

Hi Maria Margy,

Use select options and   put validation

DATA : var TYPE i.

SELECT-OPTIONS :  s_var FOR var OBLIGATORY.

AT SELECTION-SCREEN ON s_var.
   IF  ( s_var-low NOT BETWEEN '0' AND '1000' ) AND ( s_var-high NOT BETWEEN '0' AND '1000' ).
     MESSAGE : 'Please enter vale between 0 to 100' TYPE 'E'.
   ENDIF.

Hi Maria,

To get the values input at the selection screen,

you can try the FM,

  CALL FUNCTION 'DYNP_VALUES_READ'

    EXPORTING

      dyname     = sy-repid    "Program name

      dynumb     = sy-dynnr   "screen number

    TABLES

      dynpfields = gt_dynfields  "fields on selection screen

    EXCEPTIONS

      OTHERS     = 01.

  IF sy-subrc = 0.

    READ TABLE gt_dynfields INTO gs_dynfields  WITH KEY fieldname = 'NAME'.

    IF sy-subrc = 0.

     gv_name = gs_dynfields-fieldvalue.

    ENDIF.

  ENDIF.

Hi Maria,

Please check if after the FM is executed you are assigning a value to the selection screen parameter. Also

use a data type for deifining a parameter .

Thanks
