I would suggest creating a unique identifier like this example shows, using _n_ :

22932 - How to use PROC TRANSPOSE to get one record per BY group

With your data, it may be necessary to keep the _name_ variable from the first Transpose step, then create (with the DATA step) another variable in the data set FIRST for use on the ID statement in the second Transpose step. This new variable would have the values (from _name_): RelationshipN, ContactnameN.

Thanks Bari. That's very helpful, finally I have one record per personID. But I still have the problems with the column names, it will create a series of column name such as col1, col2, col3 , col4 for first contact 's relationship, name, phone, address, and col5 col6,col7, col8 for second contact's information, and so on.

How do I add a meaningful column name such as relationship1, name1, phone1, address1, relationship2, name2, phone2, address2......

Thank you very much.

## Re: Proc transpose Problem

The simplest way is double proc transpose, if they are all character type variable.

```data test;
input (id v1-v3) (\$);
cards;
11    1    0    1
11    1    0    1
11    1    0    1
21    0    1    1
31    1    1    0
41    1    1    0
41    1    1    0
;
run;
data test;
set test;
by id;
if first.id then n=0;
n+1;
run;
proc transpose data=test out=temp;
by id n;
var v1-v3;
run;
proc transpose data=temp out=want(drop=_NAME_);
by id ;
id _NAME_ n;
var col1;
run;
