Trying my luck again on this question....

App A has a join table field for projects and organizations to allow multiple organizations to be added in an embedded form within App A. 

In each each join table in each App
Project Field: Relates back to the "projects" table in the respective app
Organization Field: App A (source of truth), App B - uses a connected table from App A

Would like App B to use populate the field correctly when its information is imported to App A in a daily automation.  Projects from App B are imported over to App A daily - should I create a relationship in App B to the the project table in App A or use the one in App B. 

The related project needs to match up in both Apps to make the import process work?
