如何在Web服务端点中传递或设置条件-Acumatica

我需要根据订单类型条件提取订单。我可以通过传递一个订单类型来获取数据，但我需要获取两个订单类型的订单，无法找到或实现条件

这是代码

private static SalesOrder SOStokItem(DateTimeSearch whereCondition, StringSearch Condition, int rowCount)
    {
        SalesOrder item = new SalesOrder()
        {
            RowNumber = new LongSearch { Condition = LongCondition.IsLessThan, Value = rowCount },
            ReturnBehavior = ReturnBehavior.OnlySpecified,
            OrderType = new StringReturn(),
            OrderNbr = new StringReturn(),
        };
        if (whereCondition != null)
            item.LastModified = whereCondition;
         if (Condition != null)
        {
             //item.OrderType = new StringSearch() { Condition = StringCondition.or, Value = "RC" };
            //item.OrderType = new StringSearch() { Value = "RW" };
        }
        return item;
    }

SOAP API不包括或过滤字符串字段上的条件。 您需要发出两个SOAP请求来过滤带有or条件的销售订单
