Function Module for Rule Resolution

Use

The following excerpts from a fictitious function module for an agent determination rule, which determines the responsible agent on the basis of a release code and object to be released, can be used as an example.

The ReleaseCode and ReleaseObject elements are defined in the rule container as rule parameters.
