I need to do it in a first step in order to merge different data sets from =
a
series of quarters. And because the panel has a number of families that
rotate I need this idewntifier to merge the datasets. I will only create a
general identifier in the end.

Really nice I just created it.

I had checked that link you sent me  but only now I was able to built the
variable.

Kind wishes
