Hi, I have a report date which is end of every qtr like 31Dec2015 and Using a variable created from report date ,I have 9 datasets like data_2015Q4, data_2015Q3.....data_2013Q3.Finally I want to append these 9 datasets to create a dataset like inp_2013q3_2015q4.but the issue is this should be done dynamically.For ex, in next qtr i,e 31mar2016, I need to append datasets going back 9 quarters i,e from 2014q1 to 2016q1. How do I do this?
