Repository creation error

Hi all,

I have a problem with creation a repository.

Configuration is:

Windows 2008 R2 64-bit

ASE 15.7

Data Services 4.2 SP1

Repository manager takes me an error:

Creating repository... (BODI-300026)

Reading SQL file <C:\Program Files (x86)\SAP BusinessObjects\Data Services\admin\repo\SYBASE\sybase.sql>. (BODI-20001)

Executing SQL file <C:\Program Files (x86)\SAP BusinessObjects\Data Services\admin\repo\SYBASE\sybase.sql>. (BODI-20002)

Error or warning in executing the SQL statement <

CREATE CLUSTERED INDEX AL_LANGXMLTEXT1 ON AL_LANGXMLTEXT (OBJECT_NORMNAME, OBJECT_TYPE, OBJECT_SUBTYPE)

>.  The message from the underlying database is: <Sybase SQL Server <eim_ds> error message for operation <ct_results>: <Sybase ASE Server message number <1903> State <1> Severity <16> From Server <eim_ds>:   Message Text is: 600 is the maximum allowable size of an index.  Composite index specified is 776 bytes.

>.>. (BODI-20004)

Does anybody have any idea how to solve this error?

Thank you!
