variable does not uniquely identify observations in the using data
variable does not uniquely identify observations in the using data

Hi I'm working with two data bases but there they don't have the same observations. The first one belongs to the year 1996 and the second one to the year 2010, So the one from 1996 has 335711 observations and the other one 782970. They both have the variable coduni_96 but this variable is a code number for the universities from 1996 however I can't do the merge because I have an m:m problem. Any thoughts?
