About Case Match rulesPurpose
Use a case match rule to retrieve objects (referred to as cases in this rule) from the database and evaluate them according to criteria you specify in the rule. Such processing is sometimes called case-based reasoning.
For example, you can use a case match rule to develop a report on overdue assignments, to choose the highest-scoring supplier, or to find the best product for known criteria.
A case match rule has one of two types
- A
Seek First Caserule returns the first case found with a total score equal to or higher than the cutoff score. The cutoff score is specified in the rule. - A
Seek Casesrule returns all the cases found with a criteria-matching total score equal to or higher than the cutoff score.
Access
Use the Application Explorer to access case match rules in your application. Use the Rules Explorer to list all the case match rules available to you.
Development
Complete the Retrieval tab before the Evaluation tab. For Seek First Case rules, complete the optional sort fields on the Retrieval tab after saving the form; then save again.
Delegation
After you complete initial development and testing, you can delegate selected case match rules to line business managers. The Evaluation tab of the Case Match form provides managers with access to the fields most often updated.
For each case match rule in your application, consider which business changes might require rule updates, and whether to delegate the rule to non-developers who then can make such updates directly. See How to build for change.
