Rule Collection Sort Step

Overview 

The Rule Collection Sort Step takes in a list of any data type and sorts data based on the outcome of a Rule. This step is an Array.sort(List, comparer) that takes in a list of items, and determines the comparer based on the evaluation of a Rule. Within the Rule Designer, there are settings that set it apart from creating a custom rule. For example, the 'Outcome Data' on the 'Result' and the 'Else' rule parts are configured for the 'RuleCollectionSortOutcome' Decisions Datatype. The 'RuleCollectionSortOutcome' data type has three constant mappings that return a different priority sort value based on the selection.
