Relations between fields

[shri]

hi ,

I am trying to bulid relation between two query subjects (two tables) with key fields, but it doesn't allow me, it comes up with error. Please see the attachment for error message. Tables are from oracle database connected with Oracle RDB Driver.

The version of the Driver and/or the Database itself may be the cause.  Check Cognos's list of Supported Databases and versions.
