Aggregate functions
Aggregate functions perform statistical analysis on numbers (and also dates or times for
some functions) in:
• several fields in a record.
• related fields whether displayed in a portal or not.
• repeating fields.
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.
The parameter values can include a numeric constant (for example, 10) or any valid
expression. A constant parameter in a formula for a repeating field affects the result for
every repetition.
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, page
149.
Values in repetitions that exceed the number of repetitions in the calculated field are
ignored. For example, a calculated field with three repetitions holds only three results,
even when one field referenced in the calculation has five repetitions.
