Error in calculated column if condition in analytical view

Hi,

I am having issue in calculating with condition in HANA. I am creating  calculated column in which my condition is

if ("OTYPE = "ZMTS", Netvalue * 10, Netvalue * 5 )

For testing purpose I even tried if ("OTYPE = "ZMTS",50,75) but still error.

my calculated column data type is "Decimal" and column type is measure.

When i try this with key figure like if(Netvalue >1000,10,5) this works fine.

Is there any different way when we are dealing with non key figures in condition.

Thanks
Sri
