Copy PO Line Prices to Item Replacement Cost
Add a new configuration parameter to automatically copy the physical one time PO line price to the item Replacement cost. If the PO line's currency is different than the institution's default currency, the amount is exchanged and copied to the item (with no currency). The possibility (for an operator, a job or an API) to update or remove the amount in the Replacement cost should remain. Customers should be free to activate or not this configuration (true/false parameter).
See this program by Meredith Foster that expedites using the API to copy PO line price to replacement cost: https://developers.exlibrisgroup.com/blog/Replacement-Cost
It may help you until Ex Libris implements the idea!

The price of the order is a good idea.
The price at the invoice is more correct but more complicated ...

...and divided by the number of items linked to the POL?
