You can map default Operators to Resources in Katana, so that when a Manufacturing Order (MO) is created, Operator(s) are assigned to tasks automatically. You don't need to manually assign Operators to Production operations on Manufacturing orders, but can edit them.
To map default Operators to Resources:
Go to the Settings screen > Resources.
Here is the list of all Resources that can be assigned to Production operations. You can assign a default Operator to each Resource.
Click on Default operator for a Resource. You will see a list of all Operators on your account (read more about adding Operators).
Select Operators from the list. You can assign one or more default Operators for the same Resource.
When a MO is created for a product, Katana assigns the default Operators to each Resource on the order.
