Change Counts and Amounts
Your company may allow you to modify the amounts allotted to attendees or to enter a general count of attendees.
Enter a count (number of unnamed attendees)
Your company may allow you to enter a "count" of unnamed attendees instead of entering each attendee individually. For example, assume that you provided lunch for a group (a doctor and 10 staff members) that attended your seminar. You would enter the doctor as usual and then create a new attendee named "Staff" and enter 10 in the Attendee Count field.
Change allotted amounts
As you add attendees to the expense, the expense amount is distributed over all attendees. Your company may or may not allow you to edit - or even view - the attendee amounts. If you are allowed to edit (adjust) the individual attendee amounts, the amount fields will be editable.
