Change Order Relationships

Hello,

we are exploring the possbility to create relationships between change orders. In particular, the main idea is to create a relationship of dependancy between change orders (for example prevent the closure of target change order before the completion of source change order).

We read the documentation about relationships and we found:

1. You can select a Relationship Type (on the Relationships tab) after the relationship is created. Here are the relationship types: Fulfills, Fulfilled by, Impacts, Impacted by, Verifies, Verified by, Validates, Validated by, Tracks, and Tracked by, and Split by import.

What is the meaning of these values and how they behave in the system?
