value entry in parameters

[Former Member]

hi

I have a statement like

Parameters : material type mara-matnr which actually gives me all the values that can be entered when i press F4

however i can also enter any other value....Is their a way i can force the user to enter from only those values coming in F4

Hi,

you can do validation  for the material number(matnr)

or

Using foreign keys, you can easily create value checks for input fields

Hi Hema,

Validate using

At selection-screen on p_matnr.

example

DATA : wa_matnr TYPE mara-matnr.

PARAMETERS : p_matnr TYPE mara-matnr.

AT SELECTION-SCREEN ON  p_matnr.
   SELECT matnr FROM mara
   INTO wa_matnr
   WHERE matnr = p_matnr.
   ENDSELECT.

   IF sy-subrc NE 0.
     MESSAGE 'Wrong Material' TYPE 'E'.
   ENDIF.

Hi Hema,

You should do a validation check. While execution, you can check if the value entered in the field matches an entry in MARA table with Select MATNR from MARA into LMatnr where

matnr = P_matnr ( your Parameter ).

If sy-subrc NE 0.

Message ..Not valid.

Hi,

Try this below code.

At Selection screen on p_matr.

IF p_matr IS NOT INITIAL.

SELECT SINGLE matnr

                 FROM mara

                 INTO lv_matnr

                 WHERE matnr EQ p_matr.

IF sy-subrc NE 0.

"Display your error message.

ENDIF.

ENDIF.

      dynpfields TYPE TABLE OF dynpread WITH HEADER LINE.

PARAMETERS: p_id(20) TYPE c MODIF ID grp.

AT SELECTION-SCREEN OUTPUT.

    IF screen-group1 = 'GRP'.
      screen-input   = 0.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_id.
  SELECT DISTINCT matnr

  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      retfield        = 'P_ID'
      value_org       = 'S'
    TABLES

      return_tab      = t_rtn
    EXCEPTIONS
      parameter_error = 1
      no_values_found = 2
      OTHERS          = 3.
  IF sy-subrc <> 0.
  ENDIF.

  READ TABLE t_rtn INTO x_rtn INDEX 1.
  IF sy-subrc EQ 0.
    dynpfields-fieldname = 'P_ID'.
    MOVE x_rtn-fieldval TO dynpfields-fieldvalue.
    APPEND dynpfields.

Hi,

Validate the parameter on AT SELECTION SCREEN ON event.

Hi,

You can modify SCREEN, dynamically,in your ABAP program during the PBO event of a screen. Its contents override the static attributes of the screen fields for a single screen call.

http://help.sap.com/saphelp_nw04/helpdata/en/9f/dbab6f35c111d1829f0000e829fbfe/content.htm

For this you need to write the below code in one of the MODULEs in PBO event (1000 screen of your program ).

LOOP AT SCREEN.

* you can specify IF conditions here according to your screen elements

  screen-input = 0.  " 0 will disable accepting input ; 1 will enable accepting input
MODIFY SCREEN.
ENDLOOP.
