The advantage of having a unique login for each user, especially Sales Reps is:
- Each User (Sales Rep) can create, save and share their own set of new Favourite reports that look at the data exactly how they want it.
- Only the creator of a Favourite report can change the original. If the user login is shared then other users can change things without you knowing.
- You can restrict what reports each user has access to and what subset of data they can access within these reports (e.g. limit to seeing just Customers where that user is the Sales rep).
