After you enter the Activity Date and start and end times on the screen that opens when you say Add an Activity, you can complete the registration by adding a description if you wish. After this process, you can add links, enter parameters, use basic components, edit or delete the activity via the menus on the left.
NOTE: If you are using the activities application in the basic components of other applications, the activity you entered from the relevant application record will be reflected on the screens. You do not need to use the activities application for activity entry.
E.g; If there is an activities application in the basic components of the Tasks application, you can enter the activity for your work from the task record basic components activities menu.
