Aggregate functionsAggregate functions perform statistical analysis on numbers (and also dates or times for some functions) in:
• related fields whether displayed in a portal or not.For example, you can use the Sum function to add the values listed in a portal, as an alternative to creating a report with grouped data and subtotals.When repeating field parameters (field1; field2;...) include a non-repeating field, that value is used in the result for only the first repetition unless you use the Extend function.
