A Blog or Comment has two main functions.

The first one is that everytime a user makes a change to the system, also known as a user event, the system will store that in a Blog at the place where the change is made. For example when the user changes a Part Definition setting like changing the Part State, it will be placed a note of this event in the Blog/Comments Tab of the Part Definition Form.

The second type is the one where the user can type in some Comments him self i the Blog/Comments Tab in a Form, and those will be registered at the location where the comment is provided.

Therefore most EZ-MES Objects have a Blog/Comment Tab to show and collect this information, but there is also a system wide way to interact with the Blog/Comment Object. Those can be found on the System Desktop, and is explained here in more detail.
