Hi

First of all, you cannot get 800 hrs per month... 

For counter based... it will schedule in two days... like.. 
days and hours... but.. if u schedule in IP10..it wil take 
the annual reading and schedule the dates.. So.. if the 
running hrs didn't reach, but the date reached... so.. it 
will open a order... 

Give the annual reading according to the running hrs of the 
DG.. then u will get

Ist if you want u can make strategy plan with counter base 
for that make strategy thro IP11 ( 200,400,600,800 Hrly 
operation PM check list & attach Taskl list to PM plan) 

iindly two type of schedulling one is manual other is 
automatic ,. make the program standard RISHTRA20 THROUGH 
IP10 dead line monitoring with varient for particular plan 
on periodic basis i.e. every day night or weekly basis.
 that sit you will get PM order through automatic 
schedulling.

if anybody wnt to comment on above plz mail me.
