First, it is necessary to calculate (CZK payment amount / invoice amount in currency) the exchange rate that will be used to convert the invoice values in foreign currency to CZK values.
The bank payment must then be split into multiple parts (based on the number of invoices being settled); the individual payment amounts are calculated by multiplying each invoice amount by the exchange rate calculated as described above.
As the final step, the respective payments are matched with the invoices. During matching, you will be asked whether you want to set the currency of the paying document to the currency of the invoice — answer YES. When asked whether this is a full payment, also answer YES (provided the invoice is fully settled).
After matching, an exchange rate difference may appear in the internal documents.
