The condition Layers Changed checks if there has been changes made on the Layer. This does not include changes to the Layer itself but only to Layer changes on the Content Item.

Triggers the moment any Layers were assigned or unassigned. 

Use Layer Changed in combination with AND/OR to add more conditions and further limit the number of affected Content Items. Otherwise you may update Content Items you didn’t want to.

Specific Definitions

No specific definitions required although it is recommended to add additional conditions as this rule triggers when anybody assigns or unassigns any Layer anywhere in the system. 

Was any Layer Changed?
