The purpose of the Show PurchaseOrder is to supply Purchase Order Information to another business application module. This request may be used as a response to a Get PurchaseOrder request or as a push notification of an event.

There are many possible business applications in several environments that may use this capability. Examples include:

1. A Order Management application could use this BOD to send information to a Plant Data Collection application.

2. An MRP, Inventory or Manufacturing business application could use this to obtain order information.

3. The Order Management application can notify the MRP/Inventory application when a vendor gives or changes a promise day.
