You will most likely run across this issue when searching for a vendor in a cheque requisition or purchase requisition.  The vendor you’ve searched for is in eShop and the information automatically populates the form.  The only problem is that it is not the currency you need and you can’t change it (i.e. the drop down arrow beside the currency disappears).

There is an easy fix!  Simply email Accounts Payable and give them the vendor information and currency that should be added.  They will add the currency to the vendor’s profile and advise you that the change has been made.
