            // [Scenario] by checking the order is Open. 
            // [Scenario] If not, abort process and force user to change filter with an error message
        // [Scenario] If not Do not handle the filter, abort process and force user to change filter. so standard filter works are normal

            Error                Error('Purchase Order %1 is not released', PurchaseHeader."No."); // We use "error" since filter a single document no. (Error is not recommended for common filtering)
    // _IsHandled := // No point in handling the filter or not, as Error stops the entire proces if needed
