When would I issue a draft version of a Purchase Order?

Before issuing the final version of a purchase order to the vendor, you can request a draft copy. This can be used to verify the purchase order before it is finalized. The audit process does not start until after you have issued the final copy of the purchase order. After the final copied is issued and if you make any changes to a purchase order pertinent to the vendor (i.e., cost, quantity, deliver date, etc.), the application assigns a revision number and the revised issue method is used.

You can also use the issue online method to select the original purchase order and the revised purchase order for issue.
