Why can’t I assign an employee, department, role, or branch to a new commission rule?

An entity that already has an active commission rule cannot be assigned to another — the system prevents duplicate rules on the same entity and displays a conflict message specifying the entity type (employee / department / role / branch). To resolve this:

• Remove the entity from the other active rule by editing it, or
• Change the status of the existing rule to “Inactive” and try again.
