When you use Deposit to Account: If you want to record a Receive Money transaction to a checking or credit card account that has been assigned a currency other than your home currency, you must first select the currency associated with the account.
To select the account, click the Currency button to display the Exchange Rate window. Click the arrow next to the Currency field and choose the currency associated with the account you want from the list of currencies that appears. Click OK to close the Exchange Rate window. All the checking and credit card accounts that use the selected currency will appear in the account list, along with your home currency account.
When you use Group with Undeposited Funds: The linked account for undeposited funds must be a local currency account. If you choose a foreign currency for a Receive Money transaction using the Exchange Rate window, only the Deposit to Account option will be available. (Group with Undeposited Funds)
