I have a model that I have had to go through to model parameters in order to create a geoprocessing service. Is there a way to check all sources that are being used in the model via python? I am attempting to publish a geoprocessing Service, however one of my sources is not registered with server which prevents my service from being published.
If you export the ModelBuilder to a Python script, the sources will all be listed somewhere in the resulting file.
(I don't recommend trying to run Python generated automatically by ModelBuilder, but it will quickly show you all the data sources the model/script is using.)
