How to generate a new attribute using Generate Attribute operator?

I have to generate an attribute 'YEAR' (YYYY) inside the Loop operator. what should be the mathematical function for the same? I tried using data_add(year,  eval(%{loop_forecast}), DATE_UNIT_YEAR) but it gave an expression evaluation error. Thanks in advance.

Your post is a bit vague to troubleshoot. Can you post the error message, process XML, and some data?
