"Human_Datetime" Error Cognos Report Error - Oracle

[Skippystrand]

I'm getting an unusual error in Cognos 8.4. It reads: "prepare". ORA-00904: "Human_Datetime": invalid identifier RSV-SRV-0042 Trace.

The IBM Cognos 8 error is: RQP-DEF-0177. An error occurred while performing operation 'sqlPrepareWithOptions' status='9'

Any hints on this type of error?

I would first check the Oracle error, usally when those come up it means something has changed either in your data or on the database itself.
