Summary functions

The Summary function group provides functions for creating summary fields such as:

Sum({Orders.Order Amount}, {Orders.Ship Via})

Summary fields are normally created using the Insert Summary or Insert Grand Total dialogs. They then appear in the Report Fields tree, and can be used in a formula by double clicking there. However, they do not need to be created in this way. You can create a summary field exclusively for use by your formula by filling in the arguments to one of the functions in the Summary functions section. However, any groups that refer to summary fields must already exist in the report.
