Can you tell me where you are referencing this information in the SSA course? I know we talk about rule checkin and checkout as well as ruleset versioning. I don't remember a reference to Microsoft Work Station software. We do state that Pega provides the ability to configure external attachment storage. Pega uses a Content Management Interoperability Services (CMIS) protocol to connect with an external enterprise content management system (ECM). Compatible CMIS protocols include Microsoft SharePoint and IBM FileNet.
