Increase months to current month

Kiteulf — Thu, 07 Aug 2014 13:25:18 GMT

I have this code: which generates missing months between dates. eg:

However I want to force the the second current month, which today will be July.

1	id	Char	200
2	date	Num	8	YYMMN6.
3	_TYPE_	Num	8
4	_FREQ_	Num	8
5	spend	Num	8

INPUT ID $200. date yymmn6. _TYPE_ 8. _FREQ_ 8. spend 8.;

Datalines;

2572294 201202 3 1 1

2572294 201210 3 1 1

2572294 201211 3 1 1

2572294 201307 3 1 1

2572294 201312 3 1 1

2572294 201404 3 1 1

2572294 201405 3 1 1;

run;

summary nway data= utsett99( keep= id spend date ) ;

class id date ;

var spend ;

output sum= out= summary1 ;

;

monthly_data ;* add rows for months with no spend ;

set summary1 ;

by id ;

if first.id then priordate= date ;

output ;

. ;

do while( intck( 'month', date, target) > 1) ;

'month', date, 1) ;

output ;

end ;

keep id spend date ;

;

It might help to show us what you expect for output. And your posted code has lots of stuff missing so can't really comment on that either. You may need to paste into a plain text editor such as Notepad before copy and paste to this site.

Getting the month prior to the current month is relatively easy. What am I missing?

prior_month = intnx('month', today(), -1);
