Under the sub-section Customer-Activity you will see an overview of the activities at your company connected to the customer feature. You can also edit the activities from this feature by cklicking the three dots.
This is where you list different kinds of activities through filter settings, for example activities connected to a certain sales manager and from a specific date. This makes it possible to gather statistics for, for example, booked/completed meetings during a specific period of time and for a specific group of Sales People or an individual Sales Person.
You can also filter by Customers, Status and Customer Responsibles.
Notice that the choice Responsibleis the person connected to the activity, and Customer Responsible is the person connected to the customer.
