Data Set Transformation:Summary Data Set for Customer Purchase History

Mgarret — Wed, 24 Sep 2014 21:08:03 GMT

Hi. This is a tricky data set transformation.

I need to create a summary dataset/report which tracks the flow of these purchases over time.

I have a dataset which gives a signup date for an overall service and 9 variables which give the purchase dates for different add on products. If the add on variable dates match the signup date then those add on products were included with the signup package. Any add on variable purchase date that comes after the signup date are products which are purchased during the history of the active account. This is what it looks like:

ID	signup_DT	preferredhd_tv_estbd_dt	ultimate_estbd_dt	quant_estbd_dt	FullyLoaded_estbd_dt	HB_estbd_dt	Cin_estbd_dt	time_estbd_dt	router_estbd_dt	internet_estbd_dt
98663699	4/7/14	4/9/14	4/7/14	9/12/14	10/15/14	.	4/7/14	4/7/14	4/12/14	.
33663798	4/11/14	.	4/11/14	.	4/11/14	4/11/14	4/11/14	4/11/14	6/11/14	7/15/14
43663463	5/12/14	5/12/14	5/12/14	9/5/14	9/17/14	.	.	.	.	.
77661437	5/16/14	.	5/16/14	.	10/31/14	.	5/16/14	5/16/14	11/16/14	.
85662295	5/29/14	.	.	5/29/14	.	6/12/14	.	.	11/16/14	.
36656756	6/4/14	.	.	.	6/4/14	6/4/14	6/12/14	6/4/14	6/4/14	12/4/14
67662646	6/14/14	.	6/14/14	8/31/14	.	.	6/17/14	6/14/14	.	6/22/14
55663786	6/26/14	.	.	.	8/14/14	6/26/14	7/8/14	6/26/14	11/30/14	.
44663191	8/21/14	.	9/30/14	.	.	.	.	1/12/15	.	10/31/14

The variables I’m trying to produce are:

Signup month (easy to do)
A count of the total number of signups for that month (easy to do)
A overall count of additional products which included with sign up
A variable which has all add on product values (transposed from original dataset).
A count of the different products purchased on the startup date
A count of add on products purchased after the signup date that were purchased in the same month of the signup date
Then month variables which count the additional add on products by mont

If I take just April, this is the output I'm looking for:

Sign_up_Month	Sign_up_count	Initial_Products_total	Products	Prod_Purchased_on_Signup	AddPro_ April_After_SU	May	June	July	August	September	October
April	2	8	preferredhd_tv_estbd_dt		1
April	2	8	ultimate_estbd_dt	2
April	2	8	quant_estbd_dt							1
April	2	8	FullyLoaded_estbd_dt	1							1
April	2	8	HB_estbd_dt	1
April	2	8	Cin_estbd_dt	2
April	2	8	time_estbd_dt	2
April	2	8	router_estbd_dt		1		1
April	2	8	internet_estbd_dt					1

I have attached an excel workbook with an example of the full output and the mock data set.

I having been messing with arrays to try and accomplish this but I've been having trouble. Any assistance is greatly appreciated.

I forgot to include the code I have which produces the first three vars: signup_month, Sign_up_count, Initial_Products_total

proc sort data=have;

by ID signup_DT; run;

proc transpose data=have out=have(drop=_LABEL_);

by ID signup_DT; run;

data have;

set have;

if signup_DT=COL1 then Initialprod_flag=1;run;

proc sql;

create table have as

select distinct

count( distinct ACCT_SK) as Sign_up_count ,

month (signup_DT) as signup_month,

sum (Initialprod) as Initial_Products_total

from have

group by month (signup_DT) ; quit;
