In majority of customer's environments the unique ID (Login Name) for users is a 4 letter OPID (Operator ID) or combination of letters and numbers that most people don't know what it is/means.
This makes it difficult to identify who is the contact or service recipient in a record. This is not only about the activities, so the option to use full name in the environment settings in some modules is not enough.
This is a request to get a solution similar to the "Logical Name Solution" for UCMDB in SM9.
So what user wants is all references to people to be shown by their Full Name.
While their Login Name is used in the background to handle all references.
Additional information: In most of the companies the contact.name or also the callback contact name is also a code, so in difference to an OOB system, what users see does not tell them who the user is. The reason to use a code is that several people have the same name, so then they use something that is unique, like an employee number or any other code
