Required Fields in the eCalendar Detail Applet

In the preconfigured application, the Type field is the only required field in the Calendar Detail form in the Calendar Detail view. If you make other fields required, you must predefault these fields. This is because when users create a new record or drill into a record from the calendar grid, an implicit save of the record is triggered. If any fields are required but not predefaulted, their values are null when the implicit save is triggered and an error message will be generated.

For more information about predefaulting fields, see Configuring Siebel eBusiness Applications.
