MCA Suite logs major activities which you may have seen in Contact History or Deal History at the bottom of each page. As an Administrator of the system, you may want to monitor the work being done by your employee.
The MCA Suite Activity Log displays all activities throughout the system in the past 90 days. There is also a filter by user to drill down for a specific user. The Activity Log can be found under the Admin Tab > User Admin > Logs > Activity Logs.
