Description 

Field can be any of the following:

  • a repeating field (repeatingField).
  • a field in matching related records specified by (table::field), whether or not these records appear in a portal.
  • several non-repeating fields in a record (field1;field2;field3...).
  • corresponding repetitions of repeating fields in a record (repeatingField1;repeatingField2;repeatingField3), if the result is returned in a repeating field with at least the same number of repeats.
  • several fields in the first matching record specified by (table::field1;table::field2;...). You can include fields from different tables (table 1::field A;table 2::field B...).

Notes 

  • When a referenced field is a repeating field, the Sum function returns the sum of the first repetition field, then the sum of the second repetition field, and so on.

Example 1 

An Invoice table has a portal showing line items.

Sum(LineItems::ExtendedPrice) totals the amounts for all items on the invoice.

Example 2 

A TimeBilling table has a portal showing time worked on a project. Hours is a time field.

Sum(Hours::BillableHours) returns the total number of billable hours on a project. Thus, if the portal shows 40 hours and 15:30 hours, the total billable hours are 55:30, or 55 1/2 hours.

Example 3 

In the following examples:

  • Field1 contains two repetitions with values of 1 and 2.
  • Field2 contains four repetitions with values of 5, 6, 7, and 8.
  • Field3 contains 6.

If the calculation result isn't a repeating field:

  • Sum(Field2) returns 26.
  • Sum(Field1;Field2;Field3) returns 12.

If the calculation result is a repeating field:

  • Sum(Field2) returns a repeating field with 26 in the first repetition.
  • Sum(Field1;Field2;Field3) returns a repeating field with 12, 8, 7, 8.
