A product can have three categories 'X','Y','Z'.
Now if a customer has all three product X,Y,Z or X Y or X Z then he should be categorized as having X
if he has Y or Z then he shouuld be categorized as Y
if only Z then categoried as having only Z
Customer product category
A X X
A Y
A Z
B Y Y
B Z
C X X
C Z
D Z Z
I think this is what you are looking for but without a question it's hard to tell:
data have;
infile cards dsd;
input Customer $ product $;
cards;
A,X
A,Y
A,Z
B,Y
B,Z
C,X
C,Z
D,Z
;
run;
proc sql;
create table want as
select *,min(product) as category
from have
group by customer;
What is your question?
Please try
data have;
input Customer$ product$ ;
cards;
A X
A Y
A Z
B Y
B Z
C X
C Z
D Z
;
proc transpose data=have out=want;
by customer;
var product;
run;
data want2;
merge have want;
by customer;
if first.customer and cats(of col:) in ('XYZ','XY','XZ') then category='X';
if first.customer and cats(of col:)='YZ' then category='Y';
if first.customer and cats(of col:)='Z' then category='Z';
drop _name_ col:;
run;
Thanks,
