I didn’t know it would do that #sp2010 #docversion
Its always interesting when you see something that you never expected to happen or had forgotten about, this happened to me the other week while working with an internal colleague.
We were looking at the process surrounding internal process forms and templates, in this process the version of the form or template may not necessarily be the version number stored in the SharePoint document history, so as a way to display the version I added a simple version number column called Doc Version to the library and to my surprise the column populated with data !
A quick look in the document properties showed a custom property with the same name as the library column that I just created.
A nice little feature of Office and SharePoint integration that I had forgotten about
