To make a change, an adjustment can be made within this screen per field. A number of fields have a star in the description, which means that these fields are mandatory to fill in. The fields that do not have a star can be changed additionally. After you make changes, you can save them to change the activity. If there are already several relationships with this activity (for example, because get is linked to an element), the change made to this activity will also be reflected in the linked items.
