Your code can be shortened to

sum roa if id ==20,d
gen roa20 = roa if id == 20 & roa <= 14.167 & roa > -14.665

The effect is that roa20 is a copy of roa for id == 20 but with values
outside certain limits set to missing. Is that what you want?

But I think you have to explain what 14.167 -14.665 are. Presumably
they arise in the output of -summarize-, but we have no way of working
out what they are.
