SAS PROC Transpose - help needed

[twinkle_k12]

Hello SAS users,

I am a novice SAS user and need help for one proc transpose step.

This is my input 

Id	Participation	grade
54	Notactive	a
54	active	b
55	Notactive	c
55	active	d

And the required output format

Id	Notactive_ind	Notactive_grade	Active_ind	Active_grade
54	Non-active	a	active	b
55	Non-active	c	active	d

Could someone pour any suggestions to achieve this output please. Any help is highly appreciated

Huh?  The proposed structure seems strange as two of the columns are constants.

proc transpose data=have out=want(drop=_name_) suffix=_grade;
  by id;
  id participation;
  var grade ;
run;

If you want to have those two other columns to indicate if there is a grade for that type of participation then perhaps you want to add it afterwards?  Might be better to use 0/1 instead of 'active' as the value of that indicator.

data want2;
  set want;
  notactive_ind=not missing(notactive_grade);
  active_ind=not missing(active_grade);
run;

             Notactive_    active_    notactive_    active_
Obs    Id      grade        grade         ind         ind

 1     54        a            b            1           1
 2     55        c            d            1           1
 3     56        c                         1           0
 4     57                     d            0           1
