Add an observation with Total

Below is my current code and its output

Customer_name     Model_service_type     YTD_ACO

A                              1                                   $5

A                              2                                   $3

A                              3                                   .

A                              4                                   $1

B                              1                                   $10

B                              2                                   $2

B                              3                                   $4

proc sql;

create table tmp_model as

         select customer_name, model_service_type, sum(cost) as YTD_ACO format=dollar16.

               from dfrout.current_mod

         where year=year(date())

   group by customer_name, calculated model_service_type_name;

quit;

I would like to modify this code to output an additional observation that totals by customer.

Customer_name     Model_service_type     YTD_ACO

A                              1                                   $5

A                              2                                   $3

A                              3                                   .

A                              4                                   $1

A                              total                               $9

B                              1                                   $10

B                              2                                   $2

B                              3                                   $4

B                              total                               $16

I thought this was covered in procSQL1 class but just have not been able to find it in my book.  Any suggestions would be greatly appreciated.

Thanks

Refinement on Reeza's solution

Use descending to get sum after data

Assuming data sorted by customer_name

proc means data=dfrout.current_mod noprint descending ;

By customer_name ;

class model_service_type ;

id <any other customer level information you want to keep > ;

output out=want (Drop = _TYPE_ _Freq_)

          sum(YTD_ACO) =;

format YTD_ACO dollar16.

         model_service_type Showtotal. ;

run;

Where format Showtotal (or $Showtotal if model_service_type is character) provides the label "Total" when model_service_type is null

Re: Add an observation with Total

You're not summarizing any variables (ie sum/count/mean) in the SQL step so what does the Group by clause accomplish for you?

Do you need the data set to have those values in OR do you need to output those totals out?

Re: Add an observation with Total

Sorry i tried to simplify the code for this message and accidentally deleted my sum.   Added that back in now.  I need the output dataset to have the totals.

Re: Add an observation with Total

Consider using proc means instead.

proc means data=dfrout.current_mod noprint;

class customer_name model_service_type;

output out=want sum(cost) = YTD_ACO;

format cost dollar16.;

run;

Take a look at your output data set, want. You may need to sort it and or format it.

proc sql;

    create table want as

        select * from have

        outer union corr

        select * from (select distinct Customer_name,'total' as Model_service_type,sum(YTD_ACO) as YTD_ACO

                       from have group by Customer_name)

        order by Customer_name,Model_service_type;

Hi .. here's something with Data step..

Data have;

     input Customer_name $     Model_service_type $    YTD_ACO :dollar2.;

     datalines;

A                              1                                   $5

A                              2                                   $3

B                              3                                   .

B                              4                                   $1

C                              1                                   $10

C                              2                                   $2

C                              3                                   $4

;

run;

Proc sort data=have;

     by Customer_name;

run;

Data WANT;

     retain sum 0;

     set test1;

     by Customer_name;

     if first.Customer_name=1 then

           sum=0;

     sum+YTD_ACO;

     output;

     if last.Customer_name=1 then

           do;

                Model_service_type="TOTAL";

                YTD_ACO=sum;

                output;

           end;

     drop sum;

     format YTD_ACO dollar8.;

run;
