Select variables to merge

[ramgouveia]

I have this code:

Data M;
Merge MV (in=A) MERGEED202001B (in=B);
By UC;

If A or B;
Run;

But I want to keep only some variables of the two datasets.

Which command line should I add?

KEEP. You can add it as a data set option similar to IN.

merge missingValues(in=A keep= list of variables to keep) .... MERGEEFATURADMRSS202001B (in=B keep = list of variables to keep);
