SharePoint Online：使用 PowerShell 将托管元数据列添加到列表

SharePoint Online：如何将托管元数据字段添加到列表或库

SharePoint 中的托管元数据使用术语库中的术语集作为其允许值的来源。术语集定义一组值。例如，部门是一个术语集，“销售”是一个术语。因此，当术语集“部门”用作托管元数据列的源时，可以选择术语“销售”作为其值。下面介绍了如何将托管元数据列添加到 SharePoint Online 列表。

1. 浏览到 SharePoint Online 网站并导航到要添加托管元数据列的目标列表。
2. 在“列表”选项卡下，单击功能区中的“创建列”按钮。

3. 为新列提供名称，将字段类型指定为“托管元数据”

   

4. 向下滚动并从分类库中选择适当的术语集或术语。

   

5. 填写其他可选值，然后单击“确定”以在 SharePoint Online 列表中创建托管元数据字段。

使用 PowerShell，我们将托管元数据列添加到 SharePoint Online 列表。

PnP PowerShell 在 SharePoint Online 中添加托管元数据列

下面是使用 Add-PnPTaxonomyField cmdlet 在 SharePoint Online 列表中创建新 MMS 列的 PnP PowerShell。

#Config Variables
$SiteURL = "https://Crescent.sharepoint.com/sites/marketing"
$ListName = "Projects"

#Connect to PnP Online
Connect-PnPOnline -Url $SiteURL -Interactive

#Add a Managed Metadata column from "Regions" term set in "Deals Pipeline" Group
Add-PnPTaxonomyField -DisplayName "Region" -InternalName "Region" -TermSetPath "Deals Pipeline|Regions" -List $ListName
