I am sorry that I didn't explain my problem quit clearly. I have a set of items that need to be produced based on a run rate for example:<br>run_rate count_of_items time_to_complete time_of_day<br>30 12 24 ?<br>30 8 16 ?<br>30 7 14 ?<br>I tried to do a running total with DSum in a total query to create a time of day but cannot. each item has a unique key number. Once I get a running total of time I then can place my break and lunch times in at every 120 minutes(2 hour intervals). I need to figure out how i can get the time of day each item takes to complete plus adding in break times and lunch times. I can get running totals on a report but that does me no good in the fact that i have to add the break and lunch times in. These counts and run_rates are updated daily, so there is no fixed count or run rate. Thanks Again.
