[jayakumarmm]

I want a sas logic to identify previous month's year. For example, 1. if current month year JAN 2016 then I need to retrieve 2015 2. if current month year FEB 2016 then I need to retrieve 2016

Is your variable a SAS date, ie numeric with a date format?

If so this should work, I split it up for clarity but you can nest your functions. 

Prev_Month = INTNX('month', date_var, -1, 'B');
Prev_Year = year(Prev_Month);

[set_all__]

Using some of Reeza's code but adding 'Today' function:

Prev_months_year = year(INTNX('month', today(), -1, 'B'));
