Hi Michiko,
You want to view webi reports on iPad?
Normally, if you do a full BO installation, the mobile services are already deployed.
1) Go to CMC - Categories and create 2 categories Mobile and MobileDesigned. Add your webi reports to these categories.
2) Download 'SAP BI mobile' app on the iPad. Open the application and there'll be a button 'Connect' from where u can create a new connection.
3) Now you can test. I've did it for BO 4.0 SP6 and I suppose it should be the same for your version too.
regards,
Suraj
