I am rather a beginner in SAS. I have the following problem. Given is a big data set (my_time) which I imported into SAS looking as follows
I want to implement the following algorithm for every account look for a status and if it is equal to na then look for the same contract after one year (one year after it gets the status na) and put the information "my_date", "status" and "money" in three new columns "new_my_date", "new_status" and "new_money" like in
need something like
countifs in excel. I found loops in SAS like DO but not for the purpose to look through all rows. I do not even know for which key word I have to look.
I would be grateful for any hint.

There are many ways to solve this.
One could be to join the table with itself, with a join condition like a.year = year+1.
Another would be some kind of data step processing using retain, but that would require the data to be sorted first.
What has PROC HADOOP to do with anything in your inquiry?
