Relationship notation and path
A notation is the set of characters and symbols used to define an expression. An expression is a complete, usable binding definition in the context of scripting. An expression consists of a combination of business object name, relationship name, attribute name, and notations. The script uses the path defined by the expression to retrieve a value for variables that are associated with the launch point of the script.
The binding for a variable that receives a value from a related business object uses the standard relationship notation. The relationship begins at the current business object and can traverse multiple relationships and business objects to reach the target business object. The relationship notation uses the format of relationship name, a ‘dot’ separator, and the name of the target business object attribute. The binding for a variable against a related business object has the following format: <relationship to related business object A>.<relationship to related object B>....<relationship to related object X>.<attribute of X>.
