In Crystal Reports, a running total totals all records (in the report, in the group, and so forth) up to and including the current record. For example, if your first three records have values of 2, 4, and 6, the running total for each of the three records would be 2, 6, and 12, respectively. You can use running totals to create customized summaries and totals.
Running total fields are similar to summary fields, but provide you more control over how the total is calculated and when the total is reset. Running total fields are specifically suited to:
Display totals as they are accumulated record by record.
Total a value independent of the report's grouping.
Total a value based upon conditions you define.
Total a value after applying a group selection formula.
Total a value from the driving table in a one-to-many linking relationship.
