If you are seeing an error when trying to move an asset from Workfront to Sharepoint which says: "You do not have write access to this folder. Please select another location."
This is working as it should. The reason for this is that the first folder you see is the site collection that access has been granted to, and in that site collection there are folders that either are the default folders, or have been added to the site collection.
This is the functionality in Sharepoint as well. You can't add a document to these locations in that area directly (like a root location), but once you go into the folder then you can add them as desired.
