Unable to create Information Steward on Sybase ASE

Hi ,

I have installed Data Services 4.1 SP1 in the system. I have to use Sybase ASE as repository for all.

I have created the Information plat form services & Data Services repositories on Sybase ASE but i don't have Sybase ASE option for Information steward repository. Is there any limitation for creating repository on Sybase for Information Steward.

Please help me in this issue. This is stopping me IS installation .

Thanks & Regards,

Ramana.
