Mandatory data fields are data fields which are to be filled mandatorily in a module. If you do not fill this field, you will not be able to save in this module.
Below you will find a guide for customizing mandatory data fields.
For further general information on mandatory data fields and their application can be found here.
Rules
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 useful 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.
For date data fields, the mandatory function has no effect. It is possible to save even if such a data field is blank. However, it can be queried using another DI.
Procedure
Activate the Mandatory checkbox for the required data field in the required data area.
