Currency Translation with a Calculate Key Figure

Question

Hi,
Does anyone have experience with applying currency translation in BEX/Query Designer on a Calculated Key Figure? 
I have a need for a calculated key figure to be converted to a target currency of USD (which is already defined via RRC1).  I also need the Results Row to display the summation in USD. 
Currently, my calculated key figure displays two currencies (MYR and USD) and an incorrect summation of both currencies.
Here is how I have defined my calculated key figure:
NODIM ( 'Consumption (STOs)' ) * NDIV0 ( 'Material Source Plant Cost' / NODIM ( 'Source Plant Price Unit' ) )
I am multiplying a quantity field by amount field and then dividing by a price per unit field.  I have applied NODIM on the other fields so that the amount field will retain it's properties.
Running this query through transaction RSRT and clicking on the Generate Report button, I get the following message:
"<b>Currency translation cannot be carried out for element 20 (my calculated key figure). Element 20 neither contains a Basic key figure nor a variable with type Amount. For this reason, you cannot and do not need to perform a currency translation</b>."
From the above message, I must be setting my calculated key figure incorrectly. 
Any ideas?
Thanks!

Hello Ajeet and N Ganesh,
Thank-you for your help.  I verified that the dimensions of my key figure 'Material Source Plant Cost' was of type 0AMOUNT, so that was not the issue.
The issue was in the error message that was returned when I pressed the Generate Report button in RSRT.  Essentially, currency conversions in BEX can only be performed on basic key figures or simple replacement path variables. 
I can perform the currency translation on a SIMPLE calculated key figure that contains only the replacement path variable (where 'Material Source Plant Cost' is an attribute of my master data characteristic ZMAT_SRC).  However, I found that I cannot perform the currency translation on COMPLEX calculated key figures, like in my example above. 
To get around this currency translation issue and as suggested by the error message, I created a SIMPLE calculated key figure for replacement path variable 'Material Source Plant Cost' and performed the currency translation.  The problem with this solution is that while I get my currency translation, I also get a calculated key figure that is aggregated, according to the query layout.
To get around the aggregation issue, I also created a dummy counter as a master data attribute (of ZMAT_SRC) to capture the aggregation.  I assign a value of ‘1’ to this dummy counter/master data attribute in the update rules to my ZMAT_SRC infoobject.
I then divide my new (aggregated) calculated key figure for 'Material Source Plant Cost' by the dummy counter (which is also aggregated).  Essentially, I divided the aggregated replacement path variable by the scaling factor.  The result is that I get a new calculated key figure that has been translated into the target currency and in the correct scaling factor.  I can use the new calculated key figures in the above formula; regardless of the report is rolled-up.
Again, thanks for your help.  It gave me the pieces to solve this puzzle.
