Question 5.1.1 UMM versioning
Are message versions 100% immutable or not? Is it possible to update the status of a message by updating the status of the latest thread item?
Answer: Published versions of the messages are 100% immutable and any change that may occur needs to be published as a new updated version. Any update or change in the data fields – including Data Field (2) Event Status - will result in a new message, with a new ‘Version number’.
