Understanding Additional Setup for PO Dispatch

Before you can dispatch purchase orders externally, you must define which order status codes that your system is able to dispatch and you must set up the system to call the business services that send the purchase orders to the external supplier.

Using the processing options for the Purchase Order XPI program (P43XPI), you specify the status code range that the system uses to determine which purchase orders should be sent to the suppliers.

You use call abstraction to create a call from the Purchase Order Print program (R43500) to the CallPODispatchBSSV business function (B43E0970). The B43E0970 calls the PO Dispatch Processor business service (J43E0030). Without call abstraction, when you process the R43500, the system simply prints the purchase orders. However, if you have set up call abstraction for PO Dispatch, when you run the R43500 program, the J43E0030 business service transforms and transmits the data so that it can be received by the vendor.

You use the Call Abstraction Registration program (P0049) to set up call abstraction records.

Lastly, you must verify that document type that you are using for purchase orders exists, and that the Publish Externally option for that document type is selected. You use the Document Types Maintenance program (P40040) to set up this information. The default document type for purchase orders is OP. You can use this document type, or create your own for purchase orders.
