SharePoint Document Property Promotion and Demotion

This SharePoint tutorial explains document property promotion and demotion in SharePoint. Here we will also see, how to disable document property promotion using PowerShell and SharePoint server object model code.

The document property promotion and demotion will work in SharePoint Online or SharePoint 2010/2013/2016. But we can enable to disable property promotion in SharePoint On-premises versions only.

SharePoint Document Property Promotion

SharePoint document property promotion refers to the process of extracting values from properties of a document and writing those values to corresponding columns on the SharePoint list or document library where the document is stored.

SharePoint Document Property Demotion

SharePoint document property demotion is the process of reading list columns and writes to document properties.

To check how it works, follow the below steps:

Upload a document to a document library and set up metadata for the document. For example, I have an upload an excel document to a document library and set up metadata like below:

Once you set up the document metadata, download the document and you can rename the document or modify the document content and upload the document (Make sure the rename the document to a different name, because you can not upload a document with the same name to a document library).

Now, you will see the Department column value will be populated with value as “Training” by default like below:

But sometimes clients do not want to set default values like the above. The requirement might be to treat like a brand new document without setting up any properties, in those cases we can disable document property promotion.

We can enable or disable property promotion and demotion by using the Server object model code as well as by using PowerShell in SharePoint 2010/2013/2016.

We can not disable or enable property promotion in SharePoint Online. It will work only for SharePoint onpremise versions.
