Purpose

Use an Association rule to define a relationship between two classes based on matching values in pairs of properties. A typical use of an association rule is to enable your application to automatically add a join to a report that displays properties from both classes referenced in the association.

Association rules are one-directional. To represent the relationship between two classes A and B, you usually need to define two associations:

Where referenced

Association rules are referenced in report definition rules, to allow a report to contain data from both the instances of the Applies To class and the joined or associated class.

Standard rules

Process Commander contains more than 50 standard association rules, which are available automatically as you work with the Report Definition form. Before creating an application-specific association rule, check to see whether a standard rule is available that provides the association you need for a report.
