I created a Nintex Workflow 2010 workflow for a client that ended with the document set the workflow runs on being copied to another document library for archival. The “Copy to SharePoint” action in Nintex is used in the workflow to accomplish the library copy.
I received the following error in the workflow upon trying to copy the document set to another library:
“Failed to copy item. DocID: Site prefix not set.”
After some investigation, I determined that the a site collection feature called “Document ID Service” needed to be activated in order to copy the document set to another library. After activating the feature, the timer job that runs this service needs to run over night in order to accomplish its indexing.
The document set was succesfully copied to the archive library after retrying the workflow the next day.
