Config file name for RPD property replacement. Config file can be absolute path or relative to artifacts folder. If you are using config file from temp folder, then use FD_TEMP_DIR variable to indicate absolute path (using groovy expression for input).

You can either

1. Save config file during build operation as artifact, or
2. Extract it from SCM during deploy workflow or
3. Use absolute path to location on server. (not recommended as it requires manual setup on server)

See RPD Configuration File for details.
