Load and Performance testing for SAP Application

Hi Folks,

Am assinged for a SAP Application project for which i have to perform Load and performance testing.  SAP being complex transaction oriented system i will be only focusing on Business critical transactions

Scope of testing will be to individually test each application for reliable load and performance and then later once the complete integration of system is completed than have to do L&P for only the Critical business transactions

Have tested NON Sap applications in my career but SAP is new for me 

Please share some insights, prerequisites and configuration set up for validating SAP scenarions in Loadrunner

Appreciate your help!!!

 

Cheers...Raghav
