CCONV Calculation Command

 When trying to qualify the rate to be used by adding a cross dimension member, the calculation verifies okay but does not apply the rate I expected.

e.g, when trying to convert Actual 2007 to 2011 at a fixed rate of 2011 P12 :

FIX(Actual,"2007":"2011")

   DATACOPY LOCAL TO "CC@What_IfRate";

          FIX("CC@What_IfRate")
             CCONV "2011"->ActualP12_Ex->USD;
         ENDFIX 

ENDFIX

I expect 2007 to 2011 to be converted at the 2011 P12 rate, but it converts each year between 2007 & 2011 at that years P12 rate instead

Why does it ignore the cross dimension member ?

Thanks
