Introduction to compound properties

A compound property on a business object (the display or target object) effectively adds some property defined on another object (the source object) to the display object so that the source property behaves on the display object as if it is defined on the display object class. A compound property defines a path between the display object and source object consisting of one or more reference relations, GRM relations, or a combination of the two. The path is used to traverse between the display object and the source object. You can add compound properties to COTS and custom business objects.

Note While a compound property enables you to add a property to a business object without writing custom code or using runtime properties, a compound property is not a replacement for runtime property functionality.
