AllowSummaryDeltas

#AllowSummaryDeltas

##About

Gets or sets the value indicating whether the "Add Deltas" checkbox should be shown in the summary tab in the ReportDesigner. When this setting is on and the checkbox is checked on the report, any time there is a change in a quantity between two records, that change is calculated by taking the later value for that quantity and subtracting from it the earlier value for that quantity.

Note: The allowDeltas setting MUST be turned on to use this feature.

Default Value: true
