User status update in Equipment

HI Team,

Presently i am working on setting user status automatically on equipment master based on the transaction..I have a status profile and in that have 4 statuses in which initial is INWC ( in working condition) and BRKD ( break down ) ..

I want the system to set user status automatically to BRKD when it is assign in a order ..for that in business transaction i have given assign order as Allowed and next action as SET,but still the equipment is not updating the user status as breakdown.

Appreciate your help

Regards
