Lookup Field

This type of field allows you to look up a value from another entity based on a field in the current entity using a lookup.

Attributes

ExcludeFromAllFields If set to True, the field will not be included in the list of fields in a Data Structure if “AllFields=True” is set in a Data Structure Entity. This is useful e.g. for database function calls that are expensive and used only for lookups that would otherwise slow down the system if loaded e.g. to forms.
Field The field by which the looked-up value will be loaded, in most cases the Id (in the form of a foreign key) of the entity that contains the looked-up values.
Lookup The lookup is to be used by the data service to look up a value by the provided Field.
