PO line was setup incorrectly. It needs to allow multiple invoices to draw down from extended quant

We are cleaning up invoice match exceptions and found that when a new hospital group joined the SCM system, they were not using amount only for POs that need to have multiple invoices applied and "drawn down" from extended amount.  Have you have any situations like this at your facility and how did you clean it up?  After the first invoice is paid, an invoice match exception is created on all subsequent invoices.

Any help or suggestions would be appreciated.
