These fields indicate where the message text is stored, it's just extra information.

Message Id is the message class en Msg No is the specific message in the class. You can view these using transaction SE91. However since the actual complete message text is already shown in the log, it isn't really anything you have to worry about as a basis guy.

Developers can use it to help users understand why the message is sent, by identifying which ABAP code is responsible of sending this message (where-used list in SE91, although the where-used table is often not up to date).

Those are key to message definitions stored in SE91. In SE91 you have often a long description text with more explanation, also later Abaper could perform some search with those data.
