Hi,

 

I want a sum of total media value grouped by probability

the data set is already sorted by me

 

data sas1;
 
set d.p3;


by Probability____;
if first.Total_Media_Value=1 then tot_budget=0;
tot_budget+Total_Media_Value;
if last.Total_Media_Value then output;
run;

 

log

NOTE: Variable first.Total_Media_Value is uninitialized.
NOTE: Variable last.Total_Media_Value is uninitialized.
ERROR: BY variables are not properly sorted on data set D.P3.

Why not use proc means?

 

You can only use FIRST/LAST on variables that are included in your BY statement.

data sas2;
set d.p3;

by Probability____;
if first.Probability____=1 then tot_budget=0;
tot_budget+Total_Media_Value;
if last.Probability____ then output;

if Probability____=0 then delete;

run;

 

 

still getting the same error

log

 
ERROR: BY variables are not properly sorted on data set D.P3.

Then you probably haven't sorted your data.

Sort your data.

Post the Proc sort and data step and the corresponding log that shows the error. Clearly SAS doesn't think it is. 

All values must be ascending for the probability.
