How do we enter a receipt across two Business Units

Summary

One check received for AR invoices on two business units, how do we enter the receipt?

Content

We have one client with two locations, each of which we manage in a different BU.

They send one check made out to the one BU.

How can we do a receipt for this one check from both BUs?

Not sure if this is a transaction issue, or a set-up issue.
