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;
