M27, Attempt to rollback a transaction that is not restartable

Introduced in the 1995 ANSI M[UMPS] language standard.

One of the activities that may occur in the context of transaction processing is a restart. A restart is a second (or third, or...) attempt to process the complete transaction. Whether or not a transaction is actually restarted, depends on whether it is restartable. A transaction is restartable if the initiating TStart command specifies a restartargument. A restart of a restartable transaction causes execution to resume with the initial TStart command. A restart of a non- restartable transaction ends the transaction and causes this error to occur.
