Use
Defines the cardinality of the source Data Object or the target Data Model.
For internal (parent / child) relations, the cardinality is always 1 (one-to-one relationship). For external relations, it can also be 1:n (one-to-many relationship).
Dependencies
The Property editor fields together control how the relation is represented in the metadata.
Example
The following examples show how the fields are represented in the metadata, with the relevant field underlined to highlight it.
Source Cardinality:
<Association Name="SalesOrder" sap:content-version="1">
<End Type="Z_FR_CUST.customer" Multiplicity="1" Role="FromRole_customer_zfr_salesorder" />
<End Type="Z_FR_CUST.zfr_salesorder" Multiplicity="*" Role="ToRole_zfr_salesorder_customer" />
<ReferentialConstraint>
<Principal Role="FromRole_customer_zfr_salesorder">
<PropertyRef Name="VALUE" />
</Principal>
<Dependent Role="ToRole_zfr_salesorder_customer">
<PropertyRef Name="CUSTOMERNUMBER" />
</Dependent>
</ReferentialConstraint>
</Association>
