The condition Content Relation Items Changed checks if any Content Items were removed or assigned from a specific relationship field e.g. check if Press Kit material changed and trigger validation of the new material (assign Review Layer, note with order and appropriate permissions).
Triggers the moment anything changed in the provided Relationship Field, either an item was assigned or unassigned.
The ID is used in the Business Rule, so you can update the list item attributes any time.
Supports JSON path syntax which you can test here: https://jsonpath.com.
Any changes to the Hero Shots that require validation?
