Exchange rate zero

What causes this issue?

You have entered an exchange rate of 0.
The system interprets this as an unavailable exchange rate.
In the case of a currency conversion, this exchange rate would be
ignored and the system would continue with the next oldest exchange
rate other than 0.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
