How to handle IDR Invoices when Invoice Unit Price and Qty are different to Purchase Order

Summary:

We are trying to figure out how best to approach this situation with IDR matching.

Purchase Order: Qty 7200 @ 1.5088 Each

Supplier Invoice: Qty 300 @ 36.210 Each

In this instance the supplier is classing a unit as a case of 24.

IDR is matching to the PO as per the invoice and the invoice is therefore on price hold.

What is the best way to handle this situation? I want to suggest the PO be raised as per the invoice but these are inventory items and so there may be costing implications.

We are also only using EA, HR and DY for UOMs
