# Drop all observations from an id if id appears in a given list

[ Edited ]

I have a dataset "excluded_id" that has unique people identified by varA varB varC

And then a master dataset "all_claims", with multiple observations per unique person (as identified by a unique combo of varA varB varC)

How might I drop all observations in "all_claims" tied to a given person, if that person shows up in excluded_id?

Basically the pseudocode is something like:

data final;

set all_claims;

where varA varB varC not in (excluded_id);

The trick is that each unique person is identified by a unique combo of varA varB varC...

run;

## Re: Drop all observations from an id if id appears in a given list

** UNTESTED CODE **

Assumes both data sets are sorted by varA varB varC.

data final;
merge all_claims(in=in1) excluded_id(in=in2);
by varA varB varC;
where in1 and not in2;
run;
