hello,
I have a team with 29 employees (it could change) in 5 (it could change) groups .see table HAVE. some groups have 5 employees, and some groups have 6 employees
What I would like to obtain : divide each group into two subgroup with equal number employees whenever it is possible
for groups with 5 employees, get a subgroup number that is 1,1,1,2,2
for groups with 6 employees get a subgroup number that is 1,1,1,2,2,2
many thanks in advance for your help

The proc sort is needed if your data is not sorted by the group to allow use of group as the Strata variable.
The Groups= option randomly assigns each record to one of the number indicated for each strata. The rename on the out= option is to change the name of the automatic variable Groupid created by the Groups= option. Subgroup will be numeric in the output. If you need a character variable then use the Want data set as the input to a data step to create the desired character variable.
Suggestion: Group is an option name in multiple SAS procedures. You may want to use a different variable name then group to avoid possible confusion between your variable and the option.
