Transpose data and date format

[Q1983]

data HAVE;

input Group $ _NAME_ $ mth_28FEB2013 mth_31MAR2013;

datalines;

Central AAPP 1000 2500

Pacific BBER 1 100

PACIFIC BRMM 2 150

;

run;

Group	_NAME_	mth_28FEB2013	mth_31MAR2013
Central	AAPP	1000	2500
Pacific	BBER	1	100
PACIFIC	BRMM	2	150

I want to transpose based on the month entry(current a character.  I would also need to define a new variable called value to "house" the number from the date I need to read it as a date9 as follows

Group	_NAME_	Month	Value
Central	AAPP	28FEB2013	1000
Central	AAPP	31MAR2013	2500
Pacific	BBER	28FEB2013	1
Pacific	BBER	31MAR2013	100
Pacific	BRMM	28FEB2013	2
Pacific	BRMM	31MAR2013	150

Have you attempted a PROC TRANSPOSE. This is exactly what it's designed for and will handle this automatically.

Are you able to go back to your raw data?  The DATA step can handle this based on the original data:

data want;

input Group $ _NAME_ $ @;

Month = '28FEB2013'd;

input value @;

output;

month = '31MAR2013'd;

input value;

output;

format month date9.;

run;

data HAVE;

input Group $ _NAME_ $ mth_28FEB2013 mth_31MAR2013;

datalines;
Central AAPP 1000 2500
Pacific BBER 1 100
PACIFIC BRMM 2 150
;
run;

proc transpose data=have(rename=(_name_=name)) out=want;
by group name  notsorted;
var mth:;
run;

or

data want;
set have;
array j mth:;
do over j;
month=scan(vname(j),-1, '_');
value=j;
output;
end;
drop mth:;
run;

Hi Q,

Before transpose you have to change the Original variable name (_name_) to "name" or any name as per your requirement. Here you can go with a simple solution.  

data HAVE;
	input Group $ NAME $ mth_28FEB2013 mth_31MAR2013;
	datalines;

 

Central AAPP 1000 2500

Pacific BBER 1 100

PACIFIC BRMM 2 150

;
run;

proc sort data=have;
	by Group name;
run;

proc transpose data=have out=have1 (rename=(_name_=month col1=value));
	by group name;
	var mth_:;
run;

data want (drop=month rename=(month1=month));
	set have1;
	month1=input(substr(month, find(month, '_', 1)+1), date9.);
	format month1 date9.;
run;
