# Consignment Cases
## Rollback Provider Invoice
To rollback a provider invoice for re-generation you must go to the Rollback Vendor Invoice section.
Once the order has been rolled-back it can be deleted and regenerated. To delete the order, you must open the provider purchase order.
Clicking the red DELETE PURCHASE ORDER button will remove the order from the system and allow it to be regenerated via the manual Generate Provider Orders button discussed in the earlier section.
Once the order has been regenerated, you should review again the Provider Sales Overview report to verify the calculated consignment value and the vendor invoice values match again.
