The ability to modify a purchase order depends on the status of the purchase order.

Purchase Order Not Yet Received

If the purchase order has not been received, all fields may be edited. This includes:

• quantities
• costs
• line items

Purchase Order Received but Not Yet Invoiced

If the purchase order has been received but no payable invoice has been entered, the cost of the items can still be modified.

Purchase Order Received and Inventory Still in the Lot

If the purchase order has been received and inventory remains in the lot, the following changes may be made:

• quantity received
• item cost

When quantities are adjusted, the user must specify the storage location where the quantity adjustment should be applied.

Purchase Order Received and Payable Invoice Entered

If a purchase order has been received and the payable invoice has already been entered, the purchase order cannot be modified.

In this situation, the payable invoice must be voided and reentered before any adjustments can be made.

Adding New Line Items

Once a purchase order has been received, new line items cannot be added.

If additional items must be recorded, a new purchase order must be created.

Locked Purchase Orders

If a user attempts to edit a purchase order that is locked, a warning message will be displayed.
