Automatic Assignment of Maintenance Orders 
Use
You can assign maintenance orders to investment programs in the same way as you do other measures (WBS elements and internal orders) and appropriation requests. In this way, you can budget and plan for maintenance orders using the investment program. In comparison with other measures, maintenance orders are usually created much more frequently. Therefore, the system provides functions for automatically assigning a maintenance order to an investment program position.
Features
You control the assignment of maintenance orders to program positions by means of the organizational units in the master data of the program positions and the maintenance orders. You define the necessary assignment keys and assign them to order types in IM Customizing: Capital Investment Programs
® Master Data ® Assignment of Maintenance Orders.In the assignment key, you specify the fields the system should use when automatically determining the investment program position.

Automatic Assignment of Maintenance Orders
When you create a maintenance order, the system automatically establishes the assignment to a program position, but only if the organizational units specified in the assignment key in the maintenance order agree with those in the program position. The system issues a message when a clear assignment is not possible.
