Carlo,
If you put such a constraint on your random values, it means that at
most 76 of them can be random; you need one value to bring the sum up
to 9900. This is very simple to do:
clear
set obs 77
set seed 123
gen n = rnormal(125,25) in 1/76
qui sum n
replace n = 9900-r(sum) in 77
You didn't mention what kind of random values you want, i.e. which
distribution. I assumed normal distribution with mean 125 and sd of
25.
