Parameters
This view defines the input and output parameters for the rule, organized in a hierarchical tree-like structure. Each group can expand or collapsed, making navigation and understanding of the information easier.
These parameters are the means of communication between the rules and the processes that use them.
If the rule has enabled the property Enable Relation to a Field, some parameters are automatically generated to ensure correct implementation.
Parameters can be configured in any advanced rule except those of the forms extension type.

Predefined Parameters of Rules Related to Fields

• Output
This parameter returns the results organized into pages. The parameter is of type RuleRelationOutput and that object contains the following attributes:
- results: List of results retrieved for the relation. Each item in the list is an object of type RuleValue.
- pagin: Set of pagination attributes that allow navigation between results.
RuleValue Object
Each option in the results list is a RuleValue object, and that object contains the following attributes:
- code: A unique identifier for each value.
- value: Description of the value.
