How to access WORKITEMS_SNAPSHOT ENUMERATIONS Enumerations Table in Birt?

I have read the tutorials and several other forum posts on this topic, but no matter what I try I can not get the WORKITEMS_SNAPSHOT ENUMERATIONS table/view to return any values in BIRT.

I have used {Current Project Area} and actual ID values for the PROJECT_AREA_ITEMID, which works on other tables, but the enum table will not return values.  I have used parameters and actual values in filters.  

One interesting symptom is that when creating a new data set the ENUMERATIONS table does not show up in the list but if I type it into table name area by hand BIRT shows the four columns the table/view is suppose to have (according to the information I have read).

I have the same issue with 2 separate instances of Jazz, one using Oracle and the other DB2.  I am not sure if the data warehouse jobs are not setup correctly or what.  I am currently using version 4.0.5, but I had the same issue prior to upgrading from 4.0.3. 

I really need to create some reports that include custom attributes (enums) so if anyone has any ideas or advice on how to troubleshoot this I would certainly appreciate it!

Thanks in advance,

Rob
