Hi deepuk23,
According to your description, when you use the IIF() function in the report you got some error,right?
The issue can be caused by the column1 and column2 have different datatype, I assumed that one is integer and another is float, when the Column1 is 0 or null,  because IIF() function always evaluates both the true part and the false part, even
though it returns only one of them, it will throw out the error. 
To resolve the issue, you should use a nested IIF() function to avoid the zero-divisor in any rate like below:
=IIF(Fields!Column1.Value=0,0,((Fields!Column2.Value - Fields!Column1.Value)/(IIF(Fields!Column1.Value=0,1,Fields!Column1.Value))))
For more information, please refer to this article:
