Doubt related to fleet management

Hi all,

I have below querries related to fleet master record :

1. I have done all settings for fleet master record and getting consumption vlaues also correctly .Now in the consumption values from pop up we have two vlaues related to maintenance plant .. next service due date , order number ... here i have maintened MP for the fleet vehicle and getting the next service due date but not getting the order no ... i believe the order no tht is previously completed ? and in my MP i have some call objects tht MO and are compelted but still i am not getting the order no?

2. My understanding is IFCU tcode is for entry of consumption of fuel counters but i could find even other counter also like i have defined fuel and distance counter .. here in the tcode i could find both the counters .. anybody plz clarify this ?
