Hi Lucas,
I am also getting this same error and as mentioned by other people here, note 2250455 does not give a clear solution. It just says "Fix the procedure so that it will return a valid filter string". Could you please help me understand what to fix in the procedure?
And also this issue is not only with a single analytic view. Any new analytic view created is giving the same error. So I think something has to be fixed centrally which will fix this issue with all the analytic views and prevent it from occurring again for a new view created.
Thanks,
Arindam
