@poojas It would be worth giving a try by doing as follows:

Approach - 1:
1. Change the data type of the input in the expression to 'Any Type'
2. Cast the input from 'Any Type' to Decimal in the expression.

Approach - 2:
Else cast the contents of the desired column in the datasubset to Decimal and then pass the resultant data to the expression.

So, in either of the case make sure that the data of type 'Number Decimal' is passed to the expression because the data we obtain from the portal report is not the same as the data type we see in the portal report.

Hope the above approach might give you some leads.
