Required Field Indicator
An asterisk (*) is used to indicate that a field is required. The system determines this based on the field's configuration. When a field becomes required because of an algorithm and not the field's configuration, however, the system will not add an asterisk.
Note:
If a page includes a grid, fields within a row may be marked as required.
In this situation, the field(s) within the grid are only required if the row is being populated.
