How to overwrite values in dataset

[Justin9]

Hi, I have currently got a dataset called 'Values'. Please can someone tell me the best code to use for me to overwrite the value in the row where level_description=" ", so that instead of the 0.072129349 that is currently there, I would like it to be 0.104143 instead?

In a data step:

if missing(level_description) then do;
  value = 0.104143;
end;
