How to Print Observations that Come after a certain number of total units

johnjinkim — Thu, 16 Apr 2015 00:43:20 GMT

I am trying to figure out a way to print out all observations after a certain number of units has been reached. As an example:

Row Member Units Date

1 A 4 1/1/2015

2 B 3 1/1/2015

3 A 3 1/5/2015

4 A 3 1/6/2015

5 B 8 1/8/2015

6 A 6 1/11/2015

For this example, I would like all rows/observations printed out once a unique member has reached over 10 units. Dates have been sorted because the interest is in how many observations and types of observations there are after 10 units has been reached. .

So the output should be:

Row Member Units Date

1 A 6 1/11/2015

2 B 8 1/8/2015

Any help in figuring out how to determine the output would be appreciated!

As an aside, I am able to determine the total number of units and number of members > 10 units with:

proc sql ;

select member, sum(units) as totalunits ;

from data

group member

having totalunits > 10 ;

run ;

data have;
input Member $ Units Date :mmddyy10.;
format date mmddyy10.;
datalines;
A 4 1/1/2015

B 3 1/1/2015

A 3 1/5/2015
A 3 1/6/2015

B 8 1/8/2015

A 6 1/11/2015
;

proc sort data= have out=have1;
by member date;
run;

data want;
sum=0;

do until(last.member);
set have1;
by member;
sum+units;

if sum>10 then
output;
end;

drop sum;
run;

What if I were interested in only outputting observations after 5 dates of service (regardless of units)?

So only the following row should print out:

1/11/2015

Sorry for the late response as I haven't been active here. "Regardless of units" or is regardless of member sort? I am asking this to make proper business sense. There is only 4 service dates for member A.

Anyway taking the notsorted "have" , a super simple logic below should suffice:

data have;
input Member $    Units     Date :mmddyy10.;
format date mmddyy10.;
datalines;
           A               4          1/1/2015
        B               3          1/1/2015

A 3 1/5/2015
A 3 1/6/2015

B 8 1/8/2015

A 6 1/11/2015
;
data want;
set have;

if mod(_n_,6)=0 then
output;
run;
