After calling XDO data engine, error is coming but report is completing.

Question

There is a strange situation i am facing with one XML report.XML data definition of this report has two trigger.
One before report trigger and other after report trigger.
While running(using concurrent program) the report is completed with following error:
(This is the part of report log file)
Calling XDO Data Engine...
[050609_051508614][][EXCEPTION] SQLException encounter while executing data trigger....
java.sql.SQLException: ORA-06502: PL/SQL: numeric or value error: character to number conversion error
ORA-06512: at line 4
     at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)
     at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:331)
     at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:288)
After this error, before report trigger is getting called and it is completing successfully as per log file:
--(Part of report log file)
Calling Procedure JEITPSSR
Completed Call to Procedure JEITPSSR
End of Before Report
Post-processing of request 658631 completed at 06-MAY-2009 17:15:09.
The problem is that "after report" trigger is not getting called,because i have added one debug message which is not getting printed in the log file.
Snippet of XML data definition file:
<dataTrigger name="afterReportTrigger" source="XXXX_pkg.XX_AMOUNT_TO_PAY_UPDATE(:AMOUNT_TO_PAY)"></dataTrigger>
I am wondering how after getting error from XDO data engine ,process is continuing and why afterreport trigger is not executing.
Please guide me .
Thanks,
Rahul

Answer 1

You pl/sql package is failing with
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
it means, you are trying to convert a string to number, and it fails.
Test the package with the original data.
