Hi Steve,

You need the Multicurrency module.

We have many clients doing this same situation where they issue a PO in one currency, and receipt in that same currency but will pay or wire funds (in Payables) in a different currency that could be in home currency or another currency. Situations that we have handled include USD, CAD, Euros, and/or KRW (South Korean Won). So your Euro PO and subsequent Payment in USD is definitely a feature set of Adagio Multicurrency.

Worth noting as well, that many other accounting solutions cannot handle this.

You need to ensure that the Bank is not associated with AP control account set to make this work after MC is installed. And this can be done without much pain if the client is already using Multicurrency.

The downside if you don't already have Multi-Currency installed is that it will require doing a MC conversion to the entire distribution modules and financial suite, and this is not a trivial task as you are aware, but is doable with some GridView Read/Write.(Your and my favourite Adagio Module)

Best,
Brian
