msquery: 09815 PRS RCI Result column name must be identifyer
 

Hi,

When i tru to add a total to a column in msquery i get the following error:
msquery: 09815 PRS RCI Result column name must be identifyer

I tried to search for a understandable solution, but couldn't find one. I am
sure i'm not the only one who ran into this error.
Does somebody got a solution for me?
