Layer rules allow that entities are positioned automatically in a certain Data Flow Layer when those are displayed.
There are 2 different types of rules:
Option 1: Derive Layer by entity type
The following rule will cause that all MultiProviders will be added to the "Virtualization" Layer:
Option 2: Derive Layer from a certain digit in the technical name
The following rule will cause all entities with digit "R" on position 2 of the technical name will be added to the "Reporting" Layer:
Up to three values can be entered.
In case certain entities should be set to a different Layer, you can overrule these general rule by assigning single entities directly to a Layer (via the context menu of the entity). A direct assignment of an entity to a certain Layer always overrules the here described general rules.
So the priorities for positioning entities in a certain Layer are:
- Check for a direct assignment
- If no direct assignment is set, check if the entity type assignment exists (option 1).
- If none of the above options are set, check if the technical name fits a "letter rule” (option 2).
In case no assignment or rule is found for an entity, it will be placed in a Layer named "Unassigned".
