How to Dynamically Evaluate Formulas in Salesforce Apex?

Dynamic Formula Evaluation allows developers and administrators to build and analyze formula expressions in real time, based on changing context or data inside Salesforce. This contrasts with traditional static formulae, which are often expressed in fields or rules and evaluated only inside the context for which they are configured. This feature is introduced in Salesforce Summer’24 as a Developer preview feature.

Code for Dynamic Formula Evalution

FormulaEval.FormulaBuilder builder = Formula.builder()
            .withType(Opportunity.SObjectType)
            .withReturnType(FormulaEval.FormulaReturnType.INTEGER)
            .withFormula(discountRule.DiscountFormula__c);
        
FormulaEval.FormulaInstance instance=builder.build();
