I remembered the first time I was using imputation, it was on AMOS. I have requested several data set, one by one. And when working with each of them, I had identical results. I discovered after this, that I was using the option "regression imputation" while the recommended option would have been "stochastic regression imputation" (even though AMOS is bad tool for making imputed data sets). In the latter option, you cannot have identical data set. And all data analysts will tell you not to work with imputation that is not "stochastic". In the first case, there is no random component (i.e., no error term), and you will under-estimate standard errors. When I said it's not possible to get identical data set, i was referring to the imputation with random component, as is usually recommended to do.
