Automatic and Periodic Allocations 
Purpose
As you plan and execute your project, you carry out periodic processing to determine all the project-specific data and make it available for Enterprise Controlling.
Periodic processing covers both plan data (allocations) and actual data (period-end closing).

Archiving orders for projects
You can archive orders for projects at an early stage. However, the order values remain available for display in the project information system, because they are updated in the WBS element to which the orders are assigned.
For more information, read the
orders for projects documentation.
No settlement information is evaluated in resource-related billing. The line-item information is evaluated in the objects originally charged. If you delete orders which have not been settled in full, this information is lost.
