Note: Reference field for currency field &1 is not maintained

What causes this issue?

No currency reference field was specified for a currency field.
Therefore, the number of decimal places for the currency cannot be
determined correctly. This leads to incorrect amounts with currencies
that do not have exactly two decimal places.
This check terminates at the first currency field that is not
maintained. Therefore, you should check all the currency fields.

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