If you open a data record and you see one or more mandatory fields, the corresponding mandatory fields are checked while saving the data record. In order to save the data record, you must fill in these mandatory fields.
In other cases, mandatory fields are not checked, such as when importing data records when you use the action service or when automatically entering primary links when archiving e-mails.
Mandatory fields can depend on specific entries, for example, in the Type and Status fields. Thus, certain fields can automatically become a mandatory field, for example, if a specific Type or Status is selected.
The administrator defines all settings for mandatory fields in the Management Console.
