This segment is used to specify the currency of the monetary amount detailed in the previous MOA segment. The CUX segment is only used if code 57 (Equivalent amount) has been used in data element 5025 of the previous MOA segment. The currency information is required only by the ordering customer and its bank.

When specifying the Reference and Target currencies for international trade, one occurrence of CUX is all that is required. The reference currency is identified in the first occurrence of composite C504, with the target currency specified in the second occurrence of C504. The rate of exchange between the two is detailed in DE 5402.

The general rule for calculating the rate of exchange is as follows;

Reference Currency multiplied by Rate = Target Currency.

Note DE 6347 : Reference currency = Debit currency Target currency = Credit currency

Example :

CUX+2:GBP+3:BEF+51.25'

Dependency Notes :

C504: The second occurrence of this composite is only used if a target currency is being specified.

5402: The rate of exchange is only used if a target currency has been identified in the second occurrence of C504.

6348: These data elements are only used when a rate of exchange is provided in data element 5402. When a rate of exchange is provided then at least one currency rate base must be specified.
