APT DWB error

[Raja]

Hi To all

I need some help in APT DWB

Current I have migrated a database from SYbase SQL Server 11 to Sybase
ASE 12.5

The database got migrated properly.

But when a user using APT DWB executes a generated a report, he is
unable to save it.

Whenever he tries to save any report he get this error -

"Error Entry in owner field doesn't refer to a user in the current
database"

Since I don't have much knowledge on APT can any one help me to solve
this problem.

Thanks in advance
