Hi,
I import data containing hospitalized cases into SAS on a daily basis. After merging and cleaning the final, cumulative dataset for the current day, I need to generate a data set that contains only the new cases (delta) for that date.
I'm not sure what function to use in order to generate the dataset with only new cases.
Thank you
Thank you Tom for your help. I really appreciate it. Just a quick follow up question. Can the process be automated since the dataset should be generated daily?

IF you have a unique identifier, say CASEID, then it is simple.
data new_today ;
merge new(in=in1) old(in=in2);
by caseid;
if in1 and not in2;
run;
