Hi....I am trying to create a variable that has the incremental count by ID and Month_Year. The problem I think has to do with the duplication of the grouping variables. Any suggestion on how to handle this...thanks.

 

Getting:

ID Month_Year Order1
2334 March 2015 1
2334 March 2015 2
2334 March 2015 3
2334 April 2015 1
2334 April 2015 2
2334 April 2015 3
2334 May 2015 1
2334 May 2015 2
2334 May 2015 3
2566 March 2015 1
2566 March 2015 2
2566 March 2015 3
2566 April 2015 1
2566 April 2015 2
2566 April 2015 3
2566 May 2015 1
2566 May 2015 2
2566 May 2015 3

If you are just trying to calculate the values for group then I think that the following does what you want:

 

data want;
  set have;
  by id month_year notsorted;
  if first.id then group=1;
  else if first.month_year then group+1;
run;

1. what data are you starting with?

2. what is your current program?

3. what is the rule you wish to use to take the input and make the desired output?

 

we are not mind readers.

--------------------------
The hash OUTPUT method will overwrite a SAS data set, but not append. That can be costly. Consider voting for Add a HASH object method which would append a hash object to an existing SAS data set

Would enabling PROC SORT to simultaneously output multiple datasets be useful? Then vote for
Allow PROC SORT to output multiple datasets
