Calcluation view with Where condition

Hello Team,

I have created a Graphical Calculation view and to extract the accounting data from last 2 years from certain standard tables.

Currently View is working fine and it extracting the data for all the Years with the required columns in output.

I have a column ERDAT (creation date) from which I have created calculation column with Year.

but here my problem is I could not find a provision to set last 2 years data alone to extract from in the calculation view.

could you please help me out on this.

If possible to provide a provision in scripted calculation view, please let me know with an example.

Thanks,

Munvar Basha.
