Hi @Prashant_Ph,

Not entirely certain what you want. So I take a stab guessing you want the max profit per year. You can use proc means for that. Assign the YEAR. format to the date to specifiy the required aggregation level of year.

data profit;
   infile cards dlm='#';
   length type $200;
   format pdate date9.;
   input pdate : mmddyy10. type $ profit;
cards;
1/6/2009#Delivery Truck#16413.8242
1/7/2009#Regular Air#18527.1684
1/22/2009#Delivery Truck#17506.2518
2/15/2009#Delivery Truck#15227.6924
3/21/2009#Regular Air#34399.4625
8/21/2009#Delivery Truck#15688.9425
1/3/2010#Delivery Truck#18052.4284
10/20/2010#Delivery Truck#15904.1736
5/22/2011#Delivery Truck#19200.9844
11/19/2011#Delivery Truck#18598.6608
12/21/2011#Delivery Truck#19200.9844
5/21/2012#Regular Air#21172.5384
8/7/2012#Delivery Truck#19952.96
10/16/2012#Regular Air#20065.9887
12/2/2012#Delivery Truck#15315.7884
12/12/2012#Delivery Truck#15321.409
;
proc means max;
   class pdate;
   format pdate year4.;
run;

This is the output:

The MEANS Procedure

Analysis Variable : profit  
pdate N Obs Maximum 
2009 6 34399.46 
2010 2 18052.43 
2011 3 19200.98 
2012 5 21172.54

This should get you started. Proc means can create an output dataset if you like.

If I misinterpreted your question please elaborate and give a sample of the dersired output.

If you want a subset dataset you can select off after the sort.

proc sort data=[my data]; by year profit; run;

data [my data2];

set [my data];

by year profit;

if first.year and last.profit then output;

run;

If it's sorted by profit ascending per year, that should pull out the highest per year.

@MeganE You should take last.year for the highest profit.

proc sort data=[my data];  by year profit; run;
 
data [my data2];
  set [my data];
  by year;
  if last.year;
run;

Oh, look at that, i flipped them. Yes, you're right!

Re: highest value

jklaverstijn — Mon, 27 Jun 2016 17:22:12 GMT

@MeganE @Reeza there is no YEAR in the data that @Prashant_Ph attached.

Re: highest value

MeganE — Mon, 27 Jun 2016 17:27:43 GMT

Really? I'll admit i didn't look b/c i'm not comfortable opening files like that from people i don't know out on the internet. But wow. The original post surely implied year was part of the data...

Re: highest value

Reeza — Mon, 27 Jun 2016 18:02:50 GMT

@MeganE I agree about downloading files and year variable. It's relatively easy to calculate year anyways. Either use Year() function or year format.
