Inter-System Relations

An inter-system relation works the same as a foreign key, but instead of linking windows within the same system, it links a window to a window from a different system. This lets you pull and reference data across systems.

Creating an Inter-System Relation

1. Open the Inter-System Relation Panel

In the canvas of the window you want to add the relation to, open the Inter-System Relation section from the left bar. You will see a list of all available external systems.
