In this lesson, you will learn about:
- Describe how priorities are used in the SAP S/4HANA Defense and Security solution
- Describe how requirement priorities and delivery priorities are derived
Scenario
Priorities are assigned to requirements in Defense and Security. This chapter will go through which documents in SAP S/4HANA Defense and Security can be given priorities and how it is done.

Documents in Materials management, where priorities can be used.

If no Requirement Urgency is provided, the system will choose a default Requirement Urgency (usually: the „least urgent" according to Customizing).
In non-DFPS / Defense and Security implementations, no organizational priority can be assigned to Force Elements. Therefore, one will be assigned to the Storage Location directly.

In the Create Purchase Requisition app, and in other Defense and Security environments where the requisition is created, the operator is expected to specify an Urgency, not a Priority. The priority is determined later by the Urgency and the Force Element priority.

A mapping can be defined between the Requirement priority of purchasing documents (purchase requisition, purchase order) and the delivery priority.

Maintenance orders book materials using Material Reservations.
The requirement urgency for the reservation is derived from the maintenance order characteristics (type and priority) at the time of reservation creation for a maintenance order. When the reservation is created manually with no reference to a maintenance order, the requirement urgency can be specified manually for the reservation.

The requirement urgency of the resulting material reservation is derived from the combination of order type and order priority.

This figure provides you with an overall diagram for Priorities in procurement documents, delivery, FE, and storage location.
