使用外部列表创建外部内容类型时出错 [英] Error creating external content type with external list

问题描述

您好，

我在创建外部内容类型时遇到问题，并希望有人可以指出我在右边。方向 我正在尝试连接到SOAP服务（内部开发）并使用列表创建外部内容类型。 为了
创建列表，我们需要两个操作：  1）阅读项目操作  2）读取列表操作。 我可以创建"读取项目"操作，但是"读取列表"操作有困难。   下面的屏幕截图显示了Read List操作向导的Return Paremeter
屏幕以及我遇到的错误。 我确实找到一篇文章说明要点击该集合，然后点击"设置操作返回元素"。按钮以解决问题，但无论我对单个元素做出何种选择，该按钮都会为我显示为
灰色。 我还依次选择了每个元素，按钮仍然显示为灰色。   有人可以帮我理解我的错误吗？ 或者，这是一个
问题，问题是SOAP调用返回的方式（或者是什么），如果有的话，是否有任何特定的指针？

I'm having issues creating an external content type and was hoping someone could point me in the right direction.  I am attempting to connect to a SOAP service (internally developed) and create an external content type with a list.  In order to create the list, we need two operations:  1) Read Item operation  2) Read List operation.  I'm able to create the Read Item operation but am having difficulty with the Read List operation.   The screenshot below shows the Return Paremeter screen of the Read List operation wizard along with the errors I'm encountering.  I did find one article stating to click on the collection and then the "Set Operation Return Element" button in order to resolve the issue, but that button is grayed out for me regardless of the choices I make on the individual elements.  I've also selected each element in turn and the button remains grayed out.   Can someone please help me understand what I may be doing wrong?  Or, is this an issue with the way (or what) the SOAP call is returning and if so, any specific pointers?

谢谢

推荐答案

你好blandhorst，

Hi blandhorst,

你能不能手动从浏览器访问SOAP服务的WSDL文件？此外，要在SharePoint设计器中创建外部内容类型，请首先在SharePoint Central
管理中的安全存储服务应用程序中添加登录信息。

Are you able to access the WSDL file of the SOAP service from browser manually? Besides, in order to create the External Content Type in SharePoint designer, please first add the login information in secure store service application at SharePoint Central Administration.

有一个关于博客的博客使用Web服务创建外部内容类型，您可以查看：

There is a blog about creating external content types using web service, you can take a look at:
