ISO 10303-214:2010(E)
A Date_and_person_assignment is an object that associates a Date_and_person_organization with product data. This assignment provides additional information for the associated object. The provision of such data through this assignment has an organizational character whereas some objects require the same kind of data mandatorily in order to be semantically complete. This assignment shall not be used to associate the corresponding organizational data with an object whose attributes are referencing the organizational data directly.
EXAMPLE An example for the requirement stated is that there shall not exist a Date_and_person_assignment with a role of 'requestor' that refers to a Work_request, since this object refers directly to Date_and_person_organization in that role.
NOTE In the context of the object Date_and_person_assignment, the expression 'referenced object' means 'a concept that is conveyed within one of the instances referred to by the attribute 'is_applied_to' and not one of the instances referred to by this attribute.
EXAMPLE If applied to an instance of Item with role 'creation', the Date_and_person_assignment specifies the creation date of the part, tool, or raw material as a new object in the activity domain of the organization, and not the creation date of the instance of Item in the product management system of the organization.

The assigned_date_and_person specifies the Date_and_person_organization.
See date_and_person_assignment to date_and_person_organization for the application assertion.
