SAP XI Certification

Hi,

I received mail from SAP regarding the SAP teched. Iam planning to take the XI certification exam during the teched this year(2007). In the listing of certification exams offered they have given exam code as C_TBIT44_70 and exam level as Associate for XI certification. There are two levels given one is Associate and other is Professional. I want to know whether the above exam(Associate) will cover all the TBIT's ie., TBIT 40 to 44 or the exam is only for TBIT 44. Because I dont see the professional level for XI in the list they have sent. Thanks.

Best Regards

Suresh
