Yes, I have. You can use order by e_id, cus, ta, compute sum(col4), sum(col5) by e_id, cus, ta. I want to know if you can do it in Perl. I know there is a way to achieve the shown data structure because I did it once before with a stock file. Unfortunately, I can't figure it out this time and I can't find the code.
