How to display error message in selection screen or in same screen in sap oops concept.

[former_member846556]

I have an input field as date range, In that input field, If I give incorrect date or data not found on the date means, It should throw an error called ' Data not found', It is coming but Error was showing in the next page, It is not showing on the selection screen itself.

The error message should come in the selection screen itself.

Please do needful.

Thanks.

How about sharing the relevant code. Use the CODE button in the editor to nicely format it.

Execute the checks and first selection of data in some AT SELECTION-SCREEN event and not in the START-OF-SELECTION block. For performance only execute some tests when user click on execution

AT SELECTION-SCREEN ON SO_DATE.
  IF SSCRFIELDS-UCOMM EQ 'ONLI'  " only process when execution 
  OR SSCRFIELDS-UCOMM EQ 'PRIN'. " required, not when ENTER
    SELECT * FROM SOMETABLE INTO TABLE SOMEITAB 
      WHERE DATE IN SO_DATE.
    IF SY-SUBRC NE 0.
      MESSAGE 'Data not found' TYPE 'E'.
    ENDIF.
  ENDIF.
