I have the following code that is working correctly:
%macro new_tran;
data new_tran;
set
%do i = 01 %to &num_month;
%let val=%sysfunc(putn(&i,z2.));
newtran.pid_defaults_final_&val.&year
%end;
;
run;
%mend;
%new_tran;
I would like to add something like this:
%if &num_month = 12 %then &year= &year - 1;
I tried to use %eval() but I couldn't get it to work. &num_month = month(year()) -1. I want to make sure that next January when the report runs for December that it takes the correct year.
I tried the following but it's really just a guess as I'm not that experienced with macros. Any help will be appreciated:
%macro new_tran (num_month=12, year=2015);
%do i = 01 %to &num_month;
%let val=%sysfunc(putn(&i,z2.));
%let year_1 = %eval(&year -1);
%if num_month < 12 %then %do;
%put pid_defaults_final_&val.&year;
%end;
%if num_month = 12 %then %do;
%put pid_defaults_final_&val.&year_1;
%end;
%end;
%mend;
%new_tran;
Thanks

Make sure to reference your variables properly:
%if num_month < 12 %then %do;
should be
%if &num_month < 12 %then %do;
BUT
you probably mean
%if &i< 12 %then %do;
and
%if &i= 12 then do;
As you do not change the value for &nummonth.
If this were my project I would consider passing a start and end date and then parse over those using the date incrementing function INTNX and put using a selected format to build the names you're using. Then I would not have a problem with any period of reports (providing the data of the appropriate month year combinations exist.

Makes perfect sense. Just tested it, thanks for the help.
