How do I close an open activity?

Open activities that do not require (further) fulfillment can be closed in two ways.

As long as no realizations have been made, you can delete the activity by selecting it and clicking the Delete button or pressing delete.

It is not possible to delete activities that do have realizations. When trying this, a message will be shown. 

You can also mark the activity as completed via Actions > Mark as Complete. This works for both activities with and without realizations. No further realizations can be made for the activity once it has been completed.
