The table i have as below:

 

id        term      course         ind    

2         2016      ENC10        I         

2         2017      ENC10        E        

5        2010       MAT12       E          

5        2012       MAT12      I        

6        2011       STA11        E         

6        2013      STA11         I         

6       2015       STA11         E         

 

Table should be sot like this:

 

proc  sort data = work.a;

by id course term;run;

 

I neen only same id and course sort by term; last 'ind' should be 'E', first or second ind should be 'I'

So the table should be like below

 

id        term      course         ind    

2         2016      ENC10        I         

2         2017      ENC10        E         

6        2011       STA11        E         

6        2013      STA11         I         

6       2015       STA11         E

Again, post test data in the form of a datastep, I am not here to type in test data.  As such the logic would be something like:

data have;
set your_data;
by id; if (first.id or lag(first.id)) and ind="I" then k1=1; if last.id and ind="E" then k2=1; run; proc sql; create table WANT as select * from HAVE where ID in (select distinct ID from HAVE where k1 and k2); quit;
