Hi, I need your help solving this issue:
I have client_id with multiple date of service and I need to place in between the correct range of dates, the date that client make a payment, so for example:
Table 1
Client DateOf Service
m1256 5/2/2013
m1256 7/4/2013
m1256 11/1/2014
m1256 5/11/2015
k5678 3/4/2016
k5678 8/16/2017
r2983 5/6/2015
r2983 12/22/2015
r2983 4/29/2016
table2. Payments
Client Payment
m1256 5/16/2013
m1256 6/28/2016
k5678 5/14/2016
k5678 7/23/2016
r2983 7/3/2015
r2983 3/1/2016
r2983 5/23/2016
I think I can rank the dates in table 1 and stablish start and end date, maybe? Any help will be awesome!
You could just append the two data sets and then sort by client and date.
All your dates need to be actual SAS dates, not text strings.
And your data sets need to be in sorted order.
With those conditions in place, this would be one way to rearrange the pieces:
data want;
set table1 (rename=(DateofService=Date) in=in1)
table2 (rename=(Payment=Date) in=in2);
by Client Date;
if in1 then Action='Service';
else Action='Payment';
run;
Try it, see if you like what you get. (If you don't like it, you might have to design what you would like the solution to look like before programming can begin.)
