All validations should be done in the event AT SELECTION-SCREE (see the help for more informations): here u need to insert all code for validations and if an error occurs to raise a message

PARAMETERS: P_BUKRS TYPE T001-BUKRS.

AT SELECTION-SCREEN.

  SELECT SINGLE * FROM T001 WHERE BUKRS = P_BUKRS.
  IF SY-SUBRC <> 0.
    MESSAGE E208(00) WITH 'Company code doesn't exit'.
  ENDIF.

Hi,

Validations can be done at command AT SELECTION-SCREEN on p_datum where p_datum is the parameter field you want to validate. After AT SELECTION-SCREN you can validate using abap code. Example given below.

AT SELECTION-SCREEN on p_bukrs.

SELECT SINGLE * in lw_bukrs FROM T001

where bukrs in p_bukrs.

if sy-subrc ne 0.

display error message.

endif.

The same way you do validations in any part of the program...

I don't get your question.

I did this validation recently for a currency field, because it is obligatory I don't care if is initial.

If is not in the masters table I don't accept the currency


AT SELECTION-SCREEN.
IF NOT p_waers IS INITIAL.
      SELECT SINGLE waers INTO l_waers FROM tcurc
      WHERE waers = p_waers.
      IF sy-subrc <> 0.
        MESSAGE e001(00) WITH
                'Currency '
                p_waers
                ' doesn't exist.
      ENDIF.
    ENDIF.

In At Selection-screen event you have to validate the values of field.

if p_plant = 1000.

Display message

endif.

In addition At Selection-screen event you can validate the authorization of user.

eg.

Authority-check object 's_carrid'

ID 'carrid' FIELD pa_carr

ID 'actvt' FIELD actvt_display.

IF SY-SUBRC <> 0 .

...

ENDIF.
