Thanks Martin! Ok, but I guess I found the proper way to sort out the issue:
I have 3 rows for each individual that contain individual
characteristics + L mk info (in which I'm particularly interested)
surveyed yearly in 3 different waves. I guess the most proper way is
to separate my datasate into 3 files - 1 for each year - by obviously
renaming the variables of each year. Then, with a double merge (by my
newID) I will get the final file with 1 row for each subject.

I hope this will work
Cheers
Chiara
