I got a top level document library with some extra metadata fields such as customer, project etc.
I'd like to create a sub site for each project and include a web part which allows managing of only the project related documents there, such like the document library would be on the subsite instead of the top level site.
How is that possible wich as less effort as possible?
The reason why not each project has its own document library is i.e. sorting for customer and date instead of only for project.
