PANTHEON enables you to close outstanding items by currency. Having posted a receivable/payable in a foreign currency, this should also be the currency of the subsequent payment.
Receivables that are outstanding in foreign and local currencies should first be closed in the foreign one. This means that both the Prim. Curr. and Currency fields must be entered:

Example:
On April, 12th 2007 you issued an invoice to the Foreign Supplier in the amount of $20,000.00, which according to the exchange rate valid on that day, €1 = $ 1.25, equals €16,000.00.

The customer settles the invoice completely on May 4th, 2007 in the amount of $20,000.00. According to the exchange rate valid on that day (€1 = $1.26), it equals €15,873.02.

Close the receivable in the foreign currency in the Close outstanding items window:

The document was closed in the foreign currency but it is still open in the local one:

The document remains open in local currency for the amount of exchange differences. Later they are posted using the Automatic Posting of Exchange Differences:

After posting exchange differences, the document is closed in the local currency as well.
For examples of posting of exchange rate differences see
Posting Exchange Differences.
