The current version is the SWIFT 2015 MT standard. For information on the specific changes from the preceding standard, see The impact on testing of the update to the SWIFT 2015 MT messaging standard.
When Rational Integration Tester adopts a new SWIFT standard, existing tests continue to function as they did before. The message structures of those tests were configured by using the older standard. When you create a new test or reapply the SWIFT schema, the latest standard is used.
You can create tests that use message structures from previous versions of the SWIFT standard. You simply add user-defined fields with the appropriate two-digit number and optional letter where necessary. For more information, see Editing SWIFT messages.
