Running Totals are totals that are displayed on a record by record basis. They are a flexible and powerful way to create specialized summaries and continually incrementing totals.
Running Totals total all records in a report or a group up to and including the current record. For example, if your first three records have values of 2, 4, and 7, the running total for each of the three records would be as follows:
0 + 2 = 2
2 + 4 = 6
6 + 7 = 13
This feature totals each page and carries that total to the next page total until the Grand Total is reached on the last page.
In this topic, you want to modify the Room Capacity report to display totals of the room capacity for each building. Running totals of the room capacities should be calculated each time the room changes. You will use the Running Total feature of Crystal Reports to calculate capacity totals for all the rooms on your campus.
