If you have not gone through part-1 to part-4, I would recommend you reading them first and then continue reading from here on.
In this post, we are going to do the same stuff what we did in part-4. So open up SharePoint Designer 2010 and connect to the site.
Go to the list and libraries and find the Shared Documents. You may have a different library. I have document set in shared documents hence I have chosen shared documents.
Go to workflow and create a new workflow. I am showing this just to demonstrate the concept, the real scenario may vary and you need to use the conditions and workflow accordingly.
Now set a condition which is true and we will start the workflow on document set. We will first start with capturing the version.
Open up the actions menu and select capture the version of document set. Provide comments and major or minor version input. Save and publish the workflow. Go back to document set and run the workflow and see that we now have new version captured for the workflow.
