After I have loaded my new RPD in EM, and restarting the BI coreapplications.
Basically the symptoms I am getting are very similar to this: https://kr.forums.oracle.com/forums/thread.jspa?threadID=2129556, I have tried removing other (sampleLIte RPDs) with no luck. Not sure what else I can do. The RPD's physical layer draws data from SQL Server. Have tested the system DSN and its ok.
Here is a screenshot of the Error: http://i.imgur.com/eDZBM2Z.png. Any help appreciated.
As part of my own investigation, I went to physical layer and saw my SQL Server was set wrong. I set it to 2008 the correct version.
Also my ODBC was set at 3.5, I changed this to 2.0. After doing this I saved it and reloaded it onto EM and it all worked. Just to verify that this was indeed the root cause, I reverted the settings back to original and loaded it again. It works.
