Which Hit Policy will sum or count results?

The Collect Order Hit Policy is designed specifically to aggregate results from rules that match a condition within the decision table. When multiple rules in a decision table are triggered, the Collect Order policy allows for the summation or counting of the results produced by these rules. This is particularly useful in scenarios where you need a combined metric or aggregate value from multiple outputs, such as total sales amounts or the number of qualifying items in a dataset.

In situations where you want to obtain a total value or a count from several matching rules, the Collect Order policy serves that purpose effectively, distinguishing it from other policies that may handle rule matches differently. Other hit policies like Priority, Rule Order, and Output Order mainly focus on dealing with how rules are evaluated or which results take precedence, rather than aggregating values. Hence, the Collect Order is the appropriate choice for summing or counting results in this context.
