I've got a mutlicurrency application with several entities, and the goal is to make an IF in a bussiness rule which depends of the base currency set to that dimension. So I've download the snapshot and look for "USD" in it. Found the following:

Which seems to be the entity properties.
After that I Assumed I can use IF( @ISUDA...) or @UDA with @LIST to specified those entities with base currency USD.
I'm receiving the following error: @UDA("Entity","USD")' : 'USD' is not a valid UDA value for dimension 'Entity'
Do you know if there any other way to achieve this?
Best Regards,
