%let YYYYMM = 201704;
%let date1 = '01Apr2017'd;
%let date2 = '01May2017'd;

 

everythime we run a report, have to manually change them. can yo uplease advise how to automate these values.

 

YYYMM is the previous month and year

date1 is the first date of the previous month

date2 is the first daty of the current month

%let YYYYMM =         %sysfunc(putn(%sysfunc(intnx(month,%sysfunc(today()),-1)),yymmn6.));
%let date1  = %str(%')%sysfunc(putn(%sysfunc(intnx(month,%sysfunc(today()),-1)),date9.))%str(%')d;
%let date2  = %str(%')%sysfunc(putn(%sysfunc(intnx(month,%sysfunc(today()), 0)),date9.))%str(%')d;

Re: auto dates

Or

data _null_;
   call symputx('YYYMM',put(intnx('month',today(),-1),yymmn6.));
   call symputx('date1',intnx('month',today(),-1,'b'));
   call symputx('date2',intnx('month',today(),0,'b'));
run;

 

 

Which is much easier on my eyes than nested %sysfunc.

Yes, this does not have '01Apr2017'd but the numeric value that the date resolves to. Unless you are actually putting date1 and date2 into text output such as a title then the numeric will work just fine.
