If not working for a company that does business outside of the United States, it is difficult to understand all of the implications of the Multicurrency Management
module. In fact, I would venture to say that it is one of the least understood functions in GP despite it's obvious name.
For those of you however using the module, you may find that in these times of organizational downsizing and consolidation, Multicurrency may no longer be necessary and perhaps may need to be disabled to prevent entering transactions in other currencies. This is just what happened to a user seeking some advise

Let's start by saying that once transactions have been entered in other currencies, you may no longer use the Multicurrency Access Setup
window to disable these currencies for a Dynamics GP company. This would be, if it were possible, my preferred method to prevent a user from entering transactions in other currencies.
The only other option is to disable the module, but this is where the scare factor comes…
