Error in calculated column based on restricted measure in calculation view

Hello Experts,

I have one calculation view CV1. Here I have below restricted and calculated measures.

RM1 = 0AMOUNT (Restriction on Account Type)

RM2 = 0AMOUNT (Restriction on Employee Type)

CM1 = RM1 - RM2

Now when I am selecting CM1 in a select statement like below I am getting error

select dim1, sum(CM1) from CV1 group by dim1

However when I select restricted measures as well I get the result.

select dim1, sum(CM1), sum(RM1), sum(RM2)  from CV1 group by dim1

Anybody know the fix of this error, please help post here.

Thanks

Rakesh
