DevOps, CI/CD and Automation

Hi all,
I have a report and i want to create a Before_Report trigger which is like this :

function BeforeReport return boolean is
no_print exception;

begin
		
		dbms_application_info.set_client_info(:P_ORG_ID); 
		
		if :CF_cust_trx_type in (1080,1002,1005,1018,1022) then 
			raise no_print;
		end if;

		exception when no_print then 
			fnd_file.put_line(1,'You cannot print this invoice!');

  return (TRUE);
end;

It's compiling without errors, but after triyng to generate XML it throws me REP-1316:Before Report Trigger references column 'CUST_TRX_TYPE' at wrong frequency.


Any ideas what to do?

Report Builder 10.1.2.2.0

Thanks in advance,
Bahchevanov.
