How to do the impute phase for multiple imputation

[Therain]

Hello,

I use SAS 9.4 and I have a data set which has 7 variables: ID, a, b, c, d, e, f. There are some missing values for variables a-f. a, b and c are categorical variables and d, e, f are continuous variables. I tried the following way for the imputation phase but the missing values are still missing and not be imputed. Does anyone know the reason? Thank you!

proc mi data =have nimpute=100 out=want;
class a b c;
fcs discrim(a = b c d e f/classeffects=include);
fcs discrim(b = a c d e f/classeffects=include);
fcs discrim(c = a b d e f/classeffects=include);
var a b c d e f;
run;
