Activity slips are recorded as you create them

When you use the Multiple Slip Entry view of the Enter Activity Slip window, an activity slip is recorded when you press the Tab key to move the insertion point to the next line. If a zoom arrow appears in the Date field of an activity slip in the list, that activity slip has been recorded. If you enter a new activity slip and click Cancel after you've advanced to the next line in the list, the new activity slip won't be deleted. (Deleting activity slips)

If you've entered the minimum required information on an activity slip but haven't moved to the next line in the list, you can record the activity slip by clicking Record or by clicking the Single Slip Entry tab.
