I believe that the Hourly Sales and Labor report will do what you are looking for. Under Settings for this report, put a checkmark next to each hour (8:00am, 9:00am, 10:00am, 11:00am, etc...). When you run the report, it will show your sales for each hour of the day. For example, 11:00am will show sales from 11:00am - 11:59am; 12:00pm shows sales from 12:00pm - 12:59pm. It is not cummulative, so you will see sales for that hour, and that hour only.
If this report is run for the current day (say at 1:15pm), you will get exact sales and labor information for all hours prior to 1:00pm, and you will up to the minute data for 1:00pm through 1:15pm.
Based on what your manager is requesting, this report should suffice. Is there a reason the manager does not want the other hours of the day not showing up on the report?
