You can allow transactions in different currencies to be applied to one another, for example, if you record a purchase order in one currency and then make the corresponding payment in a different currency. You can:
- 
          Allow all currencies to be applied to one another,
 - 
          Prohibit applying any currencies to one another, or
 - 
          Specify a group of Economic and Monetary Union (EMU) currencies that can be applied to one another.
 
When you apply entries in different currencies to each other, there may be a difference between the two amounts when they are converted to LCY. You can specify how large of a difference you will allow, so that the entries can be closed. The difference will then be posted as a rounding difference.
