How to handle errors from report server in Oracle forms 11g?

I can get the status of the report as:

       report_message := RUN_REPORT_OBJECT (report_id);

rep_status := REPORT_OBJECT_STATUS (report_message);

WHILE rep_status IN ('RUNNING', 'OPENING_REPORT', 'ENQUEUED')

LOOP

rep_status := REPORT_OBJECT_STATUS (report_message);

END LOOP;

When there is an error in the Report, I woud like to have the message(STATUS) from Report Server like the one in  Enterprise manger in Oracle forms 11g.

Any solution?
