Making apex_util.get_print_document return an error message

Question

We are using apex_util.get_print_document in a process to run a report something like this:
declare
   l_report blob := null;
begin
    l_report := apex_util.get_print_document (
        p_application_id      => :APP_ID,
        p_report_query_name   => 'report_query_name',
        p_report_layout_name  => 'report_layout_name',
        p_report_layout_type  => 'rtf',
        p_document_format     => 'rtf'
   if l_report is not null and dbms_lob.getlength(l_report) > 0 then
      apex_application.g_print_success_message := 'Report Created.<br>';       
      INSERT INTO reports (attachment, date_created, filename, mime_type)
      VALUES (l_report, sysdate, 'report.rtf', 'text/rtf' );       
   else       
      apex_application.g_print_success_message := '<span style="color:#CC0000">There was a problem creating the report.</span><br>';   
   end if; 
end;And this works well most of the time. The problem is, if the report fails for some reason, apex_util.get_print_document gives no information whatsoever as to what went wrong. Is there any way at all we can find out what the problem was?

Hi,
add exception to your code.
declare
   l_report blob := null;
begin
    l_report := apex_util.get_print_document (
        p_application_id      => :APP_ID,
        p_report_query_name   => 'report_query_name',
        p_report_layout_name  => 'report_layout_name',
        p_report_layout_type  => 'rtf',
        p_document_format     => 'rtf'
   if l_report is not null and dbms_lob.getlength(l_report) > 0 then
      apex_application.g_print_success_message := 'Report Created.<br>';       
      INSERT INTO reports (attachment, date_created, filename, mime_type)
      VALUES (l_report, sysdate, 'report.rtf', 'text/rtf' );       
   else       
      apex_application.g_print_success_message := '<span style="color:#CC0000">There was a problem creating the report.</span><br>';   
   end if; 
EXCEPTION
   WHEN OTHERS THEN
      raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR- '||SQLERRM);
end;This will give proper error message.
Hope this will helps you.
