Modify Status Profile of a WBE via FM

Hi,

I'm searching for a FM or a BADI in order to set the Status profile of a WBE (with their user status) via interface.

I've found until now the STATUS_OBJECT_CREATE FM but I cannot do it works. I filled correctly:

OBJNR

OBTYP

STSMA

but the field doesn't change.

How can I solve that problem?

Thanks

Regards
