From the Serena Explorer, you can select a request and set it as the default for the Dimensions Context view. In this way, you can spare yourself the effort of manually browsing for a specific request in the Dimensions CM Context view. When you set an active request from the Serena Explorer view, that request is then supplied to the Serena Context view where you can set it as the working request.
To set an active request for the Dimensions CM Context view:
Display your requests in the Serena Explorer.
Right-click a request and select Set Active Request. This request will now appear by default as the working request when you display the Dimensions CM Context view.
