In this step you can define a default value for the accounting area for every order type and every plant.
This function allows you to form groups of orders for collective order settlement.
For example, you can assign all service objects to an accounting area.
The accounting areas must be created in Customizing for the cost accounting system.
If there is a small number of orders , the definition of accounting areas is not necessary.
Remember that you cannot settle more than 100,000 orders, for reasons of runtime.
If the total number of all active maintenance, service and CO orders is greater than 100,000, refer to note 45290 in the OSS system.
