REST PROGRAMMING EXAMPLE R_CAR

Hi

I am trying to build this example in my SAP ECC 6.0 EHP7 NW 7.4 system but the table R_CAR doesn't exist in my system.

http://help.sap.com/saphelp_nw74/helpdata/en/0f/5fb77942744afe94afafa78df57b70/content.htm?frameset=/en/0e/65f60d48f541e7ab34ed81fef41b5b/frameset.htm&current_toc=/en/33/12e0f98f494692b9777dd0ce9fba1e/plain.htm&node_id=520&show_children=false

Question:

1. How do I get r_car in my system

2. How/where do I define s_car type

Thanks

Stephen
