How do you merge matches in SAS?
To match-merge, you simply specify the data sets you would like to merge in a MERGE statement, and indicate the variables on which you would like to merge in a BY statement. One thing to keep in mind, though, is you can’t match-merge SAS data sets unless they are sorted by the variables appearing in the BY statement.

When both data sets has multiple entries for same value of common variable then it is called MANY-to-MANY relationship.
What is merging in SAS?
Match-merging combines observations from two or more SAS data sets into a single observation in a new data set according to the values of a common variable. The number of observations in the new data set is the sum of the largest number of observations in each BY group in all data sets.
