Zuora Product Selector page Submit button skips Unique field validation

[Hina]

If you find that the Zuora Product Editor Screen ignores Unique field validation when the user presses the Submit button. It doesn't save the charge(s), and navigates onwards to the next page then follow the solution provided in the reply.

To achieve this you can use a custom Quote Rules Engine plugin mentioned below. Have the logic in the runValidationRules method, and return true if OK or False to prevent user from continuing.

Quote Rule Engine Plugin Example

You can also add a zqu.ZQuoteRulesEngine.ChangeLog to the list from method parameters, and the message should display in the popup warning e.g.

global class Z_QuoteRulesEnginePlugin implements zqu.ZQuoteRulesEngine.QuoteRulesEnginePlugin{
    public boolean runValidationRules(zqu__Quote__c quote, List<zqu.ZChargeGroup> zcgList, List<zqu.ZQuoteRulesEngine.ChangeLog> logs){   
        // some logic
        if(...) { // if validation fails
            zqu.ZQuoteRulesEngine.ChangeLog log = new zqu.ZQuoteRulesEngine.ChangeLog();
            log.description = 'validation failed / some message here';
            logs.add(log);
            return false;
        }
        return true;
    }

    public void runPriceRules(List<zqu.ZChargeGroup> zcgList, List<zqu.ZQuoteRulesEngine.ChangeLog> logs){     
        return;
    }

    public Map<String, List<String>> runProductRules(zqu__Quote__c quote, List<String> ratePlanIds, List<zqu.zQuoteRulesEngine.ChangeLog> logs){
        return new Map<String, List<String>>();
    }
}
