Subject:      Billing Data question
Content-Type: text/plain; charset="iso-8859-1"

Dear List

I have billing data where every record represents a billing event for a customer. I am trying to select the intake date for the most current treatment episode (series of events), however the data only gives me the billing dates. I could select the first billing date for any given client, but some of this clients have received treatment multiple times. So I am defining new intakes if there has been a gap of billing activity longer than 6 weeks.

What I need to do, then, is select the first date of the newest treatment episode.

Data looks like this.

FULLNAM SOCSECNO SVC DATE Schmoe, Joe 123456789 CSP 01/01/2002 Schmoe, Joe 123456789 PH 01/02/2002 Schmoe, Joe 123456789 CSP 01/14/2002 Schmoe, Joe 123456789 PH 01/29/2002 Schmoe, Joe 123456789 CSP 02/01/2002 Schmoe, Joe 123456789 CFT 08/04/2002 <= Newest intake Schmoe, Joe 123456789 CSP 08/06/2002 Schmoe, Joe 123456789 CSP 09/17/2002 Schmoe, Joe 123456789 CFT 09/28/2002 Schmoe, Joe 123456789 CSP 10/05/2002 Schmoe, Joe 123456789 CFT 10/21/2002 Schmoe, Joe 123456789 CSP 10/30/2002 Schmoe, Joe 123456789 PH 11/01/2002 Schmoe, Joe 123456789 CSP 11/09/2002 Schmoe, Jane 987654321 CFT 01/01/2002 <= New Intake Schmoe, Jane 987654321 CSP 02/03/2002 Schmoe, Jane 987654321 CFT 03/04/2002 Schmoe, Jane 987654321 CSP 04/05/2002 Schmoe, Jane 987654321 CFT 05/06/2002 Schmoe, Jane 987654321 CFT 06/07/2002 Schmoe, Jane 987654321 CSP 07/09/2002 Schmoe, Jane 987654321 CFT 08/11/2002

So what I need is select the intake date for the newest treatment episode, and not necessarily the first billing date.

Please help with this.
