Numbering Instances of the Inner Join Extension Table User Property
If you add multiple Inner Join Extension Table n user properties to a business component, then you can append a value to this user property. The lowest value indicates the primary extension table. For example, the predefined Employee business component includes the following user properties:
Inner Join Extension Table 1 includes a value of S_CONTACT.
Inner Join Extension Table 2 includes a value of S_USER.
Inner Join Extension Table 3 includes a value of S_EMP_PER.
In this example, S_CONTACT is the primary extension table. For more information, see Numbering Instances of a User Property.
