SAP IS Retail Certified with no experince

Hello everyone,

                     Is there any way to get a job in SAP Companies with no experience in SAP IS Retail . Certified in SAP IS Retail 4.7 in 2008 and a BBM Graduate (2010). Any suggestions how to get interview calls?  Or the names of some companies who allow direct walk-in for freshers? You can send me direct message or mail me  :  jovebilal@live.com . Suggestions will be highly appreciated and also if anyone can help me with a list of main topics in SAP IS Retail , one should be prepared facing an interview.

Thanks & Regards,

Jove
