I would like to have an answer regarding the following topic. I want to match observations from a two year observations database with a one year observations database on basis of company keys (see below). So, does someone have an answer to match the company keys below for the two year database with the one year database? I know there is a merging command, but it does not work properly.
Regards and thank you for the effort in replying to me.
