This section outlines the differences between Creating a Purchase Order and Changing a Purchase Order:

 

Vendor Number field

The vendor number field is read-only and will be loaded after a valid purchase order number to change has been entered. Once a valid purchase order number has been entered, the vendor's information, including the vendor number will be loaded.

 

Purchase Order Number field

The purchase order number field is used to specify which purchase order should be changed. Enter the purchase order number to load in this field. If the purchase order number is not known, click the (search) button to invoke the Purchase Order Search screen.

 

Supplemental PO button

The Supplemental PO button has been added below the Edit Comment... button. Clicking this button will invoke the Select Supplemental P.O. window. For more information on using supplemental purchase order, see that section in this chapter.

 

Saving the Purchase Order

The prompt to create a supplemental purchase order will not be displayed when changing a purchase order. This is because supplemental purchase orders may be accessed directly from the change purchase order window.

 

 

When using supplemental purchase order, any changes to the items on the master PO, will not be accessible until after the mater purchase order has been saved.

 

Under these circumstances the Change PO operation will have to be completed by clicking the OK button, which saves the new detail information. Only then can the Create/Change Supplemental Purchase Order utility be run. At this point, re-reading the master PO will load the changes to the line items of the master PO.
