Your first (?) issue is not a problem -- it is an informational message if you are doing a "look-up" type merge (or "many to one" merge).

If your second question asks about how to create the lookup table of proyection values -- that depends on if you already have them stored somehow and if you can get them into aa Stata dataset. You can always use -generate- and -replace- to type them in.

By the way, it is not good form to include an offlist follow-up, provided as courtesy, as part of a message back to the full Statalist. I will not extend the courtesy again.

I have the next problem when I use merge "variable dpto agegp e1 does
not uniquely identify observations in the master data"

I know it, because every observation which has same value in dpto
agegp e1 must have the same proyection.

How a proyection can be added by dpto agegp e1 variables?
