In case anyone is interested. The table naming scheme is different between the OS componenet and the DB2 PAC in the TDW 2.1
Example - When the WPA creates the NT_Services table in the TDW, it is named "NT_Services" - complete with quotation marks.
When using the DB2 PAC and enabling warehouse data, the naming convention is much different on these tables - it still follows the Attribute Group convention but here is a sample.
KUDDB2APPLGROUP00 stores data from the Application Group 00. Note that the convention is all CAPS and does not include Quotes.
