Excerpt
A report function that stores the result of a calculation for a group or the complete report.

The field value, that was read when the group finished, is stored and returned when the group gets active again in a higher processing level.
This function can be used to calculate total values for a group, e.g. a TotalMax for the group, which returns the maximum value encountered for that field in the current group. The computed values are available to all bands of the group.

...

• field parameter is required and denotes the name of an ItemBand-field which gets summed up.
• group parameter denotes the name of a group. When this group is started, the counter gets reset to null.
