Purchase Orders 4.2
Before the two processes are explained in more detail, let’s look at the basic structure
of a purchase order.
Figure 4.24 illustrates the document flow. The basis for the delivery here is the
order (purchase order or stock transport order). The delivery, once it is created in
the SAP system, is treated as though it were a goods transport to a customer. You
can therefore edit the delivery using transportation planning. After loading, the
goods issue for the delivery is posted. The goods remain in the delivering plant
as far as stock is concerned, but are no longer freely available and have the status
“In transit.” The in-transit stock of the delivering plant is not posted into the freely
available stock of the receiving plant until the goods receipt is posted for it in the
receiving plant. The invoicing, which is usually represented as an internal offset
for stock transfers, is independent of the goods receipt posting.

the order type. The two following sections, focus on the order types UB (stock

usually refers to the subsequent processes. In contrast to the sales order, how-
