How can I remove canceled purchase orders that continue to appear as committed costs?

To remove canceled purchase orders, first finally close the purchase orders, then run the Update Project Performance Data process.

To finally close a purchase order:

1. Navigate to Procurement > Purchase Orders and access the Manage Orders task using the Tasks panel.
2. Search and select the order you want to cancel and click Actions > Close. The Close Document modal appears.
3. Select Finally Close in the Action drop-down list, optionally, provide a Reason and click OK.

For more information, see What happens if a purchasing document status is finally closed? in the Using Procurement guide.
