After executing a job where errors have occurred, you will find rows with error
message under the Detail tab of window Execute Job.
You will find error messages from the business logic here, and these error messages together
with the content of the attribute string normally gives enough information to identify
the problem.
If there are many errors, and you need other persons to evaluate it, you may want to save it to a file. Do like this :
INTFACE_JOB_DETAIL
and procedure CREATE_OUTPUT_FILE
(semicolon as column-separator).
