Is there a way to have a workflow create a SharePoint folder in a document library automatically? When a new product is created, we want to have the folder for all the stuff we keep about the product created automatically.
If you want the process fully automated, a plug-in which creates the CRM Document Location record and the folder in SharePoint is usually the way to go. Requires some development (CRM & SharePoint) knowledge and usually requires credentials be stored someplace for a SharePoint service account to handle the SharePoint work as there isn't a good way to use the current user in the context of a plug-in.
The next closest option would be to change the Document Management settings to enable automatic folder creation and the navigate to the Documents on the record and the folder would be created in SharePoint without prompting the user.
A plugin would do the trick as outlined by Jason Lattimer.However, our DocumentsCorePack comes with custom workflow activities that allow for creating document locations, folders as well as subfolders on SharePoint right inside CRM workflows.
As you are an existing DCP customer i guess this is the most easy route to go :)
