If the session writes to a target file, the PowerCenter Integration Service process creates the target file based on a file target definition. By default, the PowerCenter Integration Service process names the target file based on the target definition name. If a mapping contains multiple instances of the same target, the PowerCenter Integration Service process names the target files based on the target instance name.
The PowerCenter Integration Service process creates this file in the PowerCenter Integration Service variable directory, $PMTargetFileDir, by default.
