ISR data valid only for payment in local currency

What causes this issue?

You can only use the ISR procedure (Switzerland) when making a payment
in local currency. It follows that you cannot enter ISR data for
documents in foreign currency or line items for which an alternative
payment currency is the default.

System Response

Error message.

How to fix this error?

Either enter a payment currency or do not enter any ISR data.
