A method and apparatus for dynamically generating code that generates a mapping between territories and territorial assignees is provided. A code generator uses the territory criteria to dynamically generate the code for an assignee-to-territory-mapping-engine. The generated code uses the territory criteria and the territorial assignees to produce an assignee-to-territory-mapping. The assignee-to-territory-mapping can be used to determine the sales representatives that are responsible for a particular territorial assignee.
