Could anyone please let me know how I can randomly split a sample (750 cases) into three subsamples cointaing 250 cases each? All three subscamples must contain different cases.

first select randomly 250 cases, then sort cases so that the 500 remaining cases are on top and select 250 of those (both using select cases -> random sample of cases).
Then you can create a variable in which you combine these.
