proc sql;

You can use proc freq:

proc sort data=have; by caldt mgmt_name; run;
proc freq data=have;
 by caldt;
     table mgmt_name;
run;

Alternatively you can run:

proc sort data=have; by caldt mgmt_name; run;

data want;
 set have;
      by caldt mgmt_name;
      retain count;
      if first.mgmt_name then count=0;
      count+1;
     if last.mgmt_name then output;
run;
