Looking at what is available out there to allow sharepoint folders to be display inside ProjectWise.
One of the thing I would like to achieve, populate a PW folder with SharePoint content. This way PW become the front end for user to access and work with documents.
The other thing, SharePoint use lost of list instead of folder to group the information. if we could display a list inside a folder to populate it's content. That could be like creating a new saved search, but link to a list and saved under a specific folder.
At the moment you can display PW folders in SharePoint by integrating 08.11.11.833 web server with your SharePoint, but it doesn't work in opposite way.
You could contact your account manager and ask him to raise a call with professional services to see if there is a specialized tool for this.
Please feel free to comment if you have any further questions.
Thank you for letting me know, on the download page it is mention sharepoint 2013, do you know if 2017 is being support?
