Figure 13.5 (pg. 480) depicts the PO and related data that can be displayed in the SAP R/3 system. At the top of this display is the PO data. We can drill down here to find the related purchase requisition. At the bottom of the screen, you can see the PO history, including the goods receipt and the invoice. As noted earlier, these are “attached” to the PO. Before the invoice was accepted, a match was performed (i.e., invoice verification) to determine that the PO, goods receipt, and invoice matched (within tolerances chosen by the user).
