Definition

Specifies the type of relationship between a from-entity type and a to-entity type.

Use

The relationships can be defined as follows:

• Using relationships with the relationship type Referencing, you specify that the from-entity type is an attribute of the to-entity type.
• If you use Leading or Qualifying as the relationship type, you specify that the from-entity type is on a higher level than the to-entity type. The from-entity type is automatically taken as the key in the generated tables of the to-entity type in this case.

The difference between the relationship types Leading and Qualifying is only relevant for to-entity types with storage and use type 4. The master data of these to-entity types is processed in the context of the entity type that is assigned using the leading relationship.

For more information about the relationship types, see SAP Library under SAP ERP Central Component -> Accounting -> Financial Master Data Management -> Configuration -> Structure of the Data Model and Database Tables.

Dependencies

The following dependencies exist as regards cardinality or specifying a data element:

• 1:N is the only cardinality allowed for the relationship types Leading and Qualifying. You cannot specify a data element.
• Cardinalities 1:N and 0:N are both allowed for the relationship type Referencing. A data element can be specified in this case. However, this data element must have the same technical properties as the data element assigned to the From-entity type.
