Funnel provides several connectors to SFDC. Rather than using specific reports for these connection types, we pull all of the object data available (includes all custom properties).
Example use case:
Salesforce Order Products can be combined with the data from other connectors - most likely the Order and Products connectors since this is a way to connect them with each other. This object is called OrderItem in the API but Order Product in the user interface. Depending on your use case and data model these connectors could help you extract the sales pipeline into Funnel and beyond.
