The insertable class has some restrictions within the current version of Agile Business Suite:
Insertables cannot inherit from other classes.
Inherits and MemberPersistence properties of insertables are not displayed in the property window.
The multiplicity of insertables always equals 0.
Profiles are excluded from being a member of an insertable class.
The IsKey property is not available for attributes of an insertable.
An insertable cannot inherit from another insertable.
The Inserted property is only available for attributes of multiplicity 1 that inherit from an Insertable.
Setting the Inserted property to True:
Hides the Multiplicity property
Hides the IsPersistent property.
Hides the Direction property.
Hides the IsKey property.
Enables the HasPersistentMembers property.
When building a class with Inserted attributes, if builder cannot uniquely identify insertables, an error is reported.
