| Max function |
| Format |
Max(field{;field...}) |
| Parameter |
| field - any related field, repeating field, or set of non-repeating fields; or an expression that returns a field, repeating field, or set of non-repeating fields. |
| Parameters in curly braces { } are optional. |
| Data type returned |
| text, number, date, time, timestamp |
| Description |
| Returns the highest valid value in: |
 |
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...). |
| Examples |
| The Accounts layout has a portal showing installment payments made. |
| Max(Payments::PaymentDate) returns the most recent date a payment was made on an account. |
| 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. |
| Max(Field2) returns 8 when the calculation isn't a repeating field. |
| Max(Field1;Field2;Field3) returns 6, 6, 7, 8 when the calculation is a repeating field. |
| Note When a referenced field is a repeating field, the Max function returns the maximum value in the first repetition field, then the maximum value in the second repetition field, and so on. |
