• • 背景**

我是Azure环境的新手，所以如果问题很简单的话，请告诉我。我调用了一个带有分页的REST API。数据有多个存储在层次结构中的数组。数组包含翻译成不同语言的相同值。所以理论上，如果我只需要数组中的一种语言，数据已经是表格格式了。但是，我在拷贝活动的Map部分中无法将数据过滤为正确的语言。

• • 样本数据**

下面是一个数据示例。我为表格格式添加了3个不同的"行"。数据中有3个不同的数组：
1.["阶段"]["本地化"]
1.['不合格原因']['本地化']
1.['标题']['本地化']
由于我在一家荷兰公司工作，我们只希望返回locale =='nl-NL'的值。

"我尝试了什么"
很多google和microsoft learn页面。然而，我认为下面的动态函数可以在复制活动@filter($['stage']['localization']['locale'] == 'nl-NL')的Map部分工作，但它不能。我不能在复制活动管道中使用filter函数。我相信我可以将API调用保存到JSON文件中，然后使用数据流在数据流活动中过滤它，然后将其存储为表格格式。然而，拷贝活动中有没有直接过滤数据的方法？
非常感谢您的帮助!
