How to transpose the multiple variables?

srikanthyadav44 — Sat, 24 Aug 2019 14:13:33 GMT

dear all,

my dataset has multiple variables each variable is repeated for multiple number of years,

Each column in he dataset represent a variable-year.

I have to transpose the data based on variable by creating separate column of each variable containing all the time series

the present format of the dataset is as follows

Company Name	PBDITA2010	Depreciation2010	sales2010	PBDITA2011	Depreciation2011	sales2011	……………..	PBDITA2018	Depreciation2018	sales2018
20 Microns Ltd.	238.7	47.5	1768.2	256.1	53.3	2349.8		545	91.1	3845.7
3I Infotech Ltd.	649.6	405	5195.3	3087.6	517.5	5479.2		1578.8	71.6	2368.2
3M India Ltd.	1648.8	169.5	10912.8	1727.9	173.7	11891.2		5308.7	418	25597.6
3P Land Holdings Ltd.	70.5	11.4	701.7	41.8	16.6	989.7		15.9	0.7	1.4
A B B India Ltd.	7455.1	485.1	62419.9	3618.5	516.6	62947.7		1534.7	221.6	2341
A B C Gas (International) Ltd.	1.8	0.1	136.3	3.6	0.1	239.9		3.1	0.9	100.8
A B C India Ltd.	84.5	24.1	1442.7	197.9	42	2039.4		11.6	6.3	13.4
A B G Shipyard Ltd.	6427.9	524.1	18076.7	6837.6	630.3	20770.9		156.7	8.4	504.9

the required format should be as follows

Company Name	year	PBDITA	Depreciation	sales
20 Microns Ltd.	2010	238.7	47.5	1768.2
3I Infotech Ltd.	2010	649.6	405	5195.3
3M India Ltd.	2010	1648.8	169.5	10912.8
3P Land Holdings Ltd.	2010	70.5	11.4	701.7
A B B India Ltd.	2010	7455.1	485.1	62419.9
A B C Gas (International) Ltd.	2010	1.8	0.1	136.3
A B C India Ltd.	2010	84.5	24.1	1442.7
A B G Shipyard Ltd.	2010	6427.9	524.1	18076.7
20 Microns Ltd.	2011	256.1	53.3	2349.8
3I Infotech Ltd.	2011	3087.6	517.5	5479.2
3M India Ltd.	2011	1727.9	173.7	11891.2
3P Land Holdings Ltd.	2011	41.8	16.6	989.7
A B B India Ltd.	2011	3618.5	516.6	62947.7
A B C Gas (International) Ltd.	2011	3.6	0.1	239.9

Hi @srikanthyadav44 Pretty straight forward and has been asked many times in this forum

Keep it simple in 2 steps

data want;
set have;
array t(2010:2018,3) PBDITA2010--sales2018;
array j PBDITA	Depreciation	sales;
do year= 2010 to 2018;
 do _n_=1 to dim(j);
 j(_n_)=t(year,_n_);
 end;
 output;
end;
keep Company_Name	year	PBDITA	Depreciation	sales;
run;

proc sort data=want out=final_want;
 by year;
run;

Alternatively, Should memory be very sufficient

data _null_ ;
if _n_=1 then do;
   dcl hash H (ordered: "A",multidata:'y') ;
   h.definekey  ("year") ;
   h.definedata ("Company_Name","year","PBDITA","Depreciation","sales") ;
   h.definedone () ;
end;
set have end=z;
array t(2010:2018,3) PBDITA2010--sales2018;
array j PBDITA	Depreciation	sales;
do year= 2010 to 2018;
 do _n_=1 to dim(j);
 j(_n_)=t(year,_n_);
 end;
 rc=h.add();
end;
if z then h.output(dataset:'want');
run;

You can perhaps just use two PROC TRANSPOSE steps. Then you might not need to know how many variables or how many years are represented in the input. As long as all of the variable names end with 4 digit year numbers.

proc transpose data=have out=step1;
  by company ;
  var _numeric_;
run;

data step2;
  set step1 ;
  year = input(substr(_name_,length(_name)-3),4.);
  _name_ = substr(_name_,1,length(_name_)-4);
run;
proc sort data=step2;
  by company year ;
run;

proc transpose data=step2 out=want ;
  by company year;
  id _name_;
  var col1;
run;

Given your example data all three proposed methods should work. The following will also work, but doesn't have the limitations of the other methods. The method doesn't have any memory constraints, will work regardless of how your variable names are constructed (i.e., even if the contain prefixes, delimiters and or suffixes), and can work with any combination of numeric and character variables.

The macro can be downloaded from: https://github.com/gerhard1050/Untranspose-a-Wide-File

Once you have and compile (i.e., run) the macro, the code you would need to solve your problem would be:

%untranspose(data=have, out=want, by=Company, id=year,
 var=PBDITA Depreciation sales)


proc sort data=want;
  by year Company;
run;
