Check the tax amounts in local currency

What causes this issue?

You want to post a foreign currency document and have specified tax
amounts manually.

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

System Response

If the tax amounts in local currency are not maintained in accordance
with the exchange rate factor defined, an exchange rate difference item
arises when you simulate or post the document.

How to fix this error?

Either maintain the tax amounts in local currency in accordance with
the exchange rate factor defined or delete the tax item and add the
required tax amount in local or document currency. In the latter case,
the tax amount is translated into all related currencies.
