Source Module

HI  @Marble_Rock, 

That tab will show you all the Anaplan models from which your current model receives data. 

For example, if you import a hierarchy from Data Hub via an action, that model will appear in there. 

Please refer to the information here, it shows you more in depth information about when can be useful:  https://help.anaplan.com/anapedia/Content/Modeling/Manage_Models/Source_Models.html

Good luck!
