What to know about UYI

ISO 4217 marks UYI as a fund code: a unit used for a specific purpose, such as settlement or an index-linked unit of account, rather than the everyday currency of a country.

UYI has no minor unit, so amounts have no decimals. In an MT field such as 32A the amount still ends with a comma, for example 1500000,; any digit after the comma is rejected with error code C03.
