Decision Explainer is specifically designed to make Business Rules Engine decisions transparent to reviewers. Salesforce documents that Business Rules Engine must first be integrated with Decision Explainer so that rule executions generate explainability information and action logs. When an Expression Set evaluates grant prioritization criteria through decision matrices, Decision Explainer captures the relevant variables, formulas, values, and resulting decisions.

Reviewers then require the Decision Explainer Log History component on the relevant Lightning record page. Salesforce states that this component displays each recorded decision and lets reviewers open the details to see the variables, values, formulas, Expression Set name, and version involved.

Finally, appropriate users require Decision Explainer access. Current Salesforce documentation identifies Decision Explainer Service Access as the permission required to use Decision Explainer entities and functionality.

A separate Screen Flow is unnecessary because Salesforce supplies the dedicated Log History component. An Apex trigger is also inappropriate because Decision Explainer already records rule-execution history declaratively.
