Error in Trigger Program - RPG.

Hi,

I have a PF (say file1) with some fields like empno, name, city etc which is
keyed on EMPNO.
When a record gets inserted into this file, I want to execute a simple
trigger program ( thats the RPG program) which updates a field from another
file (say file2) with 'I'.
Now, I added this RPG program as a trigger to PF thru ADDPFTRG and tried to
check whether my RPG workes fine by simply inserting a record thru STRSQL.
The record gets added to file1, but the RPG trigger program gets some error
- 
"Trigger program or external routine detected an error."

I initiated STRDBG UPDPROD(*YES) to get into details.  The JOBLOG says - 

CONNECT to relational database PCSAS400 completed.

Please Help me executing my RPG trigger code.


Thanks and Regards,
Gauri.
