Though it may not be a good solution, Hope it helps:
.use a.dta, clear
.collapse (sum) id var1, by(year)
.save b.dta
.use a.dta, clear
.append using b.dta
rgds,

Thanks for your answer.
The collapse command not was I'm looking for. I need a command that
returns me something like:
id year var1
01 2000 10
01 2001 20
02 2000 15
02 2001 25
00 2000 25
00 2001 45
Where 00 is the "id" of the sum over ids by year.
