Greetings, @Sara_F.
It's a pleasure to see you here in the Community. I'm here to share some insights about clearing an outstanding Purchase Orders (PO) in QuickBooks Desktop (QBDT).
Deleting or closing Purchase Orders, whether it's outstanding or not, won't affect your Accounts Payable records since it's a non-posting transaction. Additionally, you don't need to set up any credit cards to delete or close them. You only need to mark them as closed.
To do this, you may pull up Transaction List by Vendor report and filter it to show the outstanding PO from 2014. Here's how:
1. Go to Reports menu at the top, then pick Vendors & Payables on the drop-down.
2. Choose Transaction List by Vendor.
3. Click Customize Report on the upper left.
4. On the Display tab, enter the date on From (01-01-2014) and To (12-31-2014) under REPORT DATE RANGE.
5. Go to the Filters tab, then enter Transaction Type on the search bar.
6. Pick Purchase Order on the Transaction Type drop-down, then OK.
7. Double-click on each transaction to view, then click Mark As Closed at the top.
8. Select Save & Close, then Yes on the pop-up notification.
I also attached some sample screenshots for your visual guide.
