I have a dataset which has a variable in which data is for example tmmd_fdf_er and i want to remove_fdf_er from the data.
I dont know whether substr can be used in this case
You can do this in various methods. One way is:
tranwrd(string,"_fdf_er","");
the string needs to be the same (upper/lower and spacing).
Or substr:
substr(string,1,index(string,"_")-1);
Or various other methods (perl RE comes to mind, plus replace etc.)

data x; a= 'tmmd_fdf_er'; b=substr(a,1,length(a)-7); c=prxchange('s/.{7}$//',-1,a); run;
