Fulfillers have the ability to edit the contents of the Activity Log that appears on Incidents (in the Notes section) and Request Items/Tasks. 

Please note: If you are missing data from tickets, check the Activity Log filter to ensure all relevant fields are selected.

To add or remove sections from the Activity Log on a ticket:

Click the filter icon on the right side of the Activity Log.

Use checkboxes to select or deselect fields you want to add or remove. (For example: deselect Sent/Received Emails if you do not wish to see details of notifications sent from ticket updates.)
