Hi vandana,
To work on SAP LS4H we need to only 3 steps :
1. Create a Analytical or Calculated view (cude as model)
- this will be a data set in the LS4H which directly sync to the Lumira server since it is installed on HANA
2. Then connect to BI launchpad http://<host>:<port>/sap/BI/Launchpad/
-you will see all the activated views then create any story and save
3. BI launchpad is similar to the Lumira desktop where you will see Visualize and compose options
-Now that you need is click on any data set and create a story and save.
- Else use desktop connect to Hana online and enter credential to access view and then create any story and publish to Lumira server.
Note : (if you are publishing from desktop to LS4H make sure that in network preferences the environment details are correctly entered).
That's all in a short and fallow user guide for more info, if you have issues and doubts kindly create a new thread and ask their that would be good for other to learn also 
.
Best Regards &Thanks,
M.Shashikiran
