Hi Krishna,
The first thing would be to configure Lumira Server to the BI platform then save the Lumira documents from your LD. SAP Lumira for Beginners : (5/5) Share Insights
These documents can then be accessed from the BI launchpad where you can edit further.
If you are new to Lumira, I would recommend you focus setting up the desktop app and get the storyboards ready in parallel to trying to connect the Desktop and the Server.
Please feel free to refer to the links in http://scn.sap.com/community/lumira/blog/2016/05/06/sap-lumira-for-beginners
Thank you,
Varun Anand
