Hi Deepthi,
Updating database using statement update can give dumps because of below issues:
"At least one line was not able to be changed, either because no appropriate line was found, or because the change would generate a line that leads to double entries in the primary key or a unique secondary index in the database table."
I would rather suggest you to call the FM in Mode 'M', i.e. Modify so if entry in table is not there to update, it will insert that record and also won't give dump.
Thanks.
