• The Mandatory function can be applied to all fields that do not accept an empty value or zero, since space or zero do not count as entry.
  • Using it for checkbox fields is not reasonable since here a check only takes place for activated checkboxes.
  • Key data fields (Idents) do not have to be set to Mandatory since they are automatically mandatory entries so that, according to the data base rules, the record becomes valid.
  • The mandatory function has no effect on date data fields. It is possible to save even if such a data field is blank. However, it can be queried using another DI.
