The Integration Service creates reject files for each target instance in the mapping. It creates reject files in the session reject file directory. Configure the target reject file directory on the Mapping tab for the session. By default, the Integration Service creates reject files in the $PMBadFileDir process variable directory.
When you run a session that contains multiple partitions, the Integration Service creates a separate reject file for each partition. The Integration Service names reject files after the target instance name. The default name for reject files is filename_partitionnumber.bad. The reject file name for the first partition does not contain a partition number.
The Workflow Manager replaces slash characters in the target instance name with underscore characters.
To find a reject file name and path, view the target properties settings on the Mapping tab of session properties.
