quit; Hi all! I referred to this link: https://communities.sas.com/t5/SAS-Programming/Merge-Multiple-tables/td-p/384279 to merge 8 tables and, again, in trouble. 1. Instead of what I wanted, around 6000 values, I obtained more than a million values due to duplicates. It looks that I used many gvkey=gvkey and fyear=fyear. I thought SAS may consider them as group by FYEAR and GVKEY but didn't. As I see in one table-on-one table merge I assumed that AND may mean each gvkey in each year. I just tried group by ~~, ~~; Yes. I got this error code; ERROR 180-322: Statement is not valid or it is used out of proper order. So... how can I get the result without duplicates? I simply want to have the outcome as I do with one table by one table. 2. I have a lot of variables in Z table and writing every single item in the above code is somewhat looking like dumb. I guess there must be a short cut to put all variables in my Z table. Do you know that kind of code? Somehow I need to finish my summer project but after that I have to take some SAS class at Udemy or whatever online courses... Thank you very much for your help
