RelationshipType in D365 FO
RelationshipType in D365 FO
In AOT > Data Dictionary > Tables > Table > Relations, you can set the value of the RelationshipTypeproperty of the new relation.
The following table describes the elements of the RelationshipType property.
Element name |
Description |
Automatic
inference |
NotSpecified |
Often the default value for the RelationshipTypeproperty. |
When the RelationshipType property
has the valueNotSpecified, the system infers an appropriate value. The
system infers the value in the following sequence: 1.
Specialization 2.
Link 3.
Composition 4.
Aggregation 5.
Association For example, if the criteria for both Composition andAggregation are
met, the system infers Composition. This is true because Composition occurs
earlier in the list. |
Specialization |
Applies only to table inheritance, to
relationships between base and derived tables. |
The system sets the RelationshipType property
toSpecialization whenever table inheritance is involved. |
Link |
Is a non-relational relationship. Link requires
that the Validate property be set to No. This type of relationship supports navigation
between forms that list many records from a table and forms that provide
detail fields for one record from the table. |
Link is meant only to support the migration of extended data type
(EDT) link relations for upgrade to Microsoft Dynamics AX 2012 from earlier
versions of the product. Migration tools create this type relationship, but
you must not. |
Composition |
Is a stronger type of Aggregation. A
table must not have more than one Composition relation. For
example, a building is composed of rooms, and a given room cannot exist in
more than one building. |
If the criteria for Composition are
met, but you manually assign the value of Aggregation or Association,
the system leaves the value as Aggregation or Association. |
Aggregation |
Is appropriate when the child table is considered
to be subordinate to the entity of the parent table. |
The system infers Aggregation when
either of the following is true: ·
The parent table
has a delete action node that is defined to use this relation node. ·
Any of the
foreign key fields for this relation in the child table have their Mandatory property
set toYes. If the criteria for Aggregation are
met, but you manually assign the value of Association, the system
leaves the value as Association. |
Association |
The concept of a standard foreign key. |
You must set the RelationshipType property
toAssociation if the system does not set the value of property to
anything, and both Aggregation andComposition are
inappropriate. |
