car-park-amount-excluded-from-av-by-design
Car park pricing in the Runwal quotation model is stored in Total_Car_Park_Amount__c as a separate formula field, feeding only into AVB_with_Car_Park_Amount__c for brokerage calculations. It is intentionally excluded from both Agreement_Value__c and Grand Total. Any requirement to include car parking in AV or invoicing is a business decision requiring a code change, not a bug.
