Thanks Steve & Bruce,

Steve – yes, I am familiar with the new code for calculated numeric values in Invoice.
I was just wondering if anyone may have come up with some work around that I have not thought of.
But as you state, there is no logic fields (yet) in the specs.

Bruce – your third option is the way that we are going. We will either use the Control Account, or an optional string field that we will call “Currency”. This way, we will be able to still manage with just the one spec file.
