st: Multiple imputation

Dear Statalisters, 

I am working with panel data and would like to do imputations because all my
variables have missing variables (all <20% missing values). I never used MI
in STATA before, and I can't find how I can set up some constraints for the
imputed values. More specifically, my variables must all have positive
values. However, when I do the imputations, some are negative. Does somebody
know how I can account for these constraints? 

Kind regards,
