For many customers, documents are just as critical as engineering documents such as CAD models and drawings and require manipulation of mulitple documents at once. The only effective means of accomplishing this is to add the documents to a Windchill Workspace. Unfortunatley, this capability is not yet available and needs to be added to Windchill. Supporting documents in Workspaces would also allow authors, reviewers and approvers to collect documents from various locations in Windchill into a common collection that can be updated and modified at anytime without navigating to all the individual documents. Please vote if you'd like to see this capability in a future release of Windchill.
