You wrote earlier "Splitting to see each month reports"

Can you please let us know the whole story? What do you intend to do with these monthly data sets?

If all this splitting data is only to support monthly reporting then there is a good chance that you don't need to split the data at all. 

Using By Group processing allows for creation of multiple reports with a single Proc call, is easier to code, maintain and also processes more efficiently.

Sample code to illustrate the concept:

data have;
  do i=1 to 20;
    date='01Jan2018'd+i-1;
    output;
  end;
  format date date9.;
  stop;
run;

%let startDt=05Jan2018;
%let endDt  =10Jan2018;

options nobyline;
title "Report for Date: #BYVAL(date)";
proc print data=have noobs;
  by date;
  var i date;
  where date between "&startDt"d and "&endDt"d;
run;

What if macros are given quotes

%let begin=‘20170101’;
%let end =‘20170501’;

How does loop works ?
