Summing up data by quarters

[maliha9999]

Hi everyone, 

I have the following dataset. Where I have created a new variable called quarter. I would like to sum together my Sales_Total for each City_Village by quarter. Then drop the month, year and date variables. My original dataset has sales values by month. 

City_ID	Reporting_YEAR	Reporting_MONTH	City_Village	Sales_Total	date	quarter
1	2018	10	A	155	21458	2018Q4
1	2018	11	A	134	21489	2018Q4
1	2018	12	A	141	21519	2018Q4
1	2019	1	A	153	21550	2019Q1
1	2019	2	A	134	21581	2019Q1
1	2019	3	A	145	21609	2019Q1
2	2018	10	B	155	21458	2018Q4
2	2018	11	B	134	21489	2018Q4
2	2018	12	B	141	21519	2018Q4
2	2019	1	B	153	21550	2019Q1
2	2019	2	B	134	21581	2019Q1
2	2019	3	B	147	21609	2019Q1

Below is the dataset I would like based on the sample dataset above. (my actual dataset has a lot more towns)

City_ID	City_Village	Sales_Total	quarter
1	A	430	2018Q4
1	A	432	2019Q1
2	B	430	2018Q4
2	B	434	2019Q1

Any suggestions for how to start the code to get the final dataset would be greatly appreciated. 

Thank you, 

Maliha

This is very simple using PROC SUMMARY.

proc summary data=have nway;
    class city_village quarter;
    var sales_total;
    output out=want sum=;
run;

In fact, you don't need to create the variable QUARTER.

proc summary data=have nway;
    class city_village date;
    var sales_total;
    format date yyq7.;
    output out=want sum=;
run;

When you have actual SAS date values often you do not need to create variables such as your Quarter as just applying the correct format in a reporting or analysis procedure will group the records as needed.

Since you didn't actually provide code to make a data set this is my take:

Proc summary data=have nway;
   class city_Id city_village date;
   format date yyQ6. ;
   var sales_total;
   output out=want (drop= _type_ _freq_) sum=;
run;
