我正在尝试扩展我们的标准fiori应用程序 - 创建销售订单。在产品列表中，我只想展示所选客户可用的产品。现在正在显示所有产品。
我尝试在视图控制器上添加一个过滤器。

但它不起作用。
有没有人有一个可以帮助我的想法。谢谢。

将变量分配给其他类似_this
var _this = this;
//then use _this. As the scope changes "this" value changes
filters.push(new sap.ui.model.Filter("CustomerNo", sap.ui.model.FilterOperator.Contains, _this.sCustomerNo));

终于找到了解决方案。在对前端实施过滤之前，我们必须首先从网关服务实施过滤。
以上代码有效，我们只需要实现网关过滤。
