Question 5 - C_S43_2023 discussion

Orders with Operation Account Assignment (OAA) are a special type of PM/CS orders that allow the detailed planning, capture and reporting of costs at the order operation level. The operations have their own settlement rules enabling more accurate cost updating of multiple assets maintained using a single PM/CS order. The mandatory characteristics of OAA orders are:

A technical object must be assigned to an order operation. This ensures that the operation is linked to a specific asset and can be settled accordingly. The technical object can be an equipment, a functional location, or a material.

Costs are stored only for the operation object. This means that the order header does not have any costs associated with it. The costs are allocated to the operations based on the actual postings of goods movements, confirmations, and invoices.

Purchase requisitions have the operation as account assignment. This means that the purchase requisitions created from the order components are assigned to the operation instead of the order header. This allows the tracking of costs at the operation level.

The characteristics that are not mandatory for OAA orders are:

Overall costs are dynamically summed up on the header level. This is an optional feature that can be activated by using the business function LOG_EAM_SIMPLICITY_2. This allows the display of the total costs of the order operations on the order header level.

The settlement rule is maintained on the header level. This is not a characteristic of OAA orders, but rather a limitation. The settlement rule for OAA orders can only be maintained on the operation level, not on the header level. This means that each operation has its own settlement rule and can be settled to different receivers.
