Hi

I am trying to read the Odata Tutorials at the below link

https://www.sap.com/developer/tutorials/xsa-sapui5.html

https://www.sap.com/developer/tutorials/xsa-sapui5-odata.html

How do I get access to the system to practice these or are they just for reading?

can some one please advise?

I dont know the primary tag also for asking this question so I have put it under Using SAP.COM
