I've just started with SAS, and I haven't been able to figure out what I'm trying to do.
I have a set of financial data with a dollar amount of transactions on multiple dates, some of which repeat. I'm trying to sum the total amount of money transferred on each date, but I have no clue how to do this.
So far I've only managed to make a new dataset of all the unique dates, but I don't know how to compare each element of it against every element of the complete set.
Got any tips on how to do this?
