• Description - optionally enter a description for the Rule Set
• Maximum Number of Rules Executions - sets the maximum input for Rule Sets that can be considered at runtime. The default maximum value is 100000.

Specifying Rule Set Data Parameters

Each rule set is a set of rules anticipating the same set of input and output data. These data parameters are specified on the Rule Set Parameters tab. Any publicly visible Structured Type and Primitive Data may be set as Rule Set parameters. Once set they will be available for use in rule conditions and actions.

The following parameter definitions can be entered and edited:

• Name - parameter name
• Direction - direction of the parameter (IN, OUT or IN/OUT)
  

  

• Data Type - data type, refer to section Data Types for details.
  

An IN Parameter must be added for each Structured Type and Primitive Data that will be used in the Rule Conditions. Similarly an OUT Parameter must be added for each one that will be used in the Rule Actions. Note that IN/OUT parameters are also supported.
