how do I combine multiple yearly costs so it only appears in one row

[fa04]

I have a four-variable dataset. Sometimes, total_cost is repeated in a fiscal_year.  I'd like to add all the costs by fiscal_year so there's only one row per org per year. Thank you!

data have;
length organization_name $10.;
input project_number organization_name fiscal_year total_cost;
cards;

1 orgA 2013 200
2 orgA 2014 300
3 orgA 2014 500
4 orgA 2014 200
5 orgB 2022 300
6 orgB 2022 400
7 orgB 2023 400
8 orgC 2012 200
9 orgC 2013 450
10 orgC 2013 1100

run;

These types of questions, where you want to calculate some statistic (in this case the sum) for different groups, is a job for PROC SUMMARY.

data have;
length organization_name $10.;
input project_number organization_name fiscal_year total_cost;
cards;
1 orgA 2013 200
2 orgA 2014 300
3 orgA 2014 500
4 orgA 2014 200
5 orgB 2022 300
6 orgB 2022 400
7 orgB 2023 400
8 orgC 2012 200
9 orgC 2013 450
10 orgC 2013 1100
;

proc summary data=have nway;
    class organization_name fiscal_year;
    var total_cost;
    output out=want sum=;
run;
