Understanding running totals

Running total fields are similar to summary fields but allow more control over how the total is calculated and when it is reset. Running total fields are specifically suited to perform the following totaling functions:

• show values of a total accumulate as it is calculated record by record
• total a value independent of the report's grouping
• total a value conditionally
• total a value after a group selection formula has been applied
• total a value from the driving table in a one-to-many linking relationship.
