I am making a report using smartforms. I am successful in showing data but problem is if if i put a value in parameters that does not exist is database, the smartform runs and related fields shows as empty fields. But the form is running. I want to show error message if the parameter values dose not matches with the database values. The message will show as Document not exists
So i used related error msg here like
if sy-subrc ne 0. message e357. endif.
But it is not working for passing values to smartform. It works if i use in classical report. Plz help me on this issue.
