Report on Cost And Utilization in PM Module

Question

Hi Experts,
I want some help in generating a report called Cost And Utilization in PM Module.
Any body can help me with some documents or if any body created same kind of report in Pm just do provide me some details on how create the report.
The requirement of this report is as follows,
This Report is generated from the service order or the notification which ever is latest on the equipment in the date range given by the user.
In Report I want to calculate the field Estimated Hours.The main problem we are having here is the Hour Meter infobject is of Type characteristic it is not key figure.
Based on the User input Date range the Estimated Hours calculation needs to be done.The Estimated Hours are calculated from Estimated Hours Begin and Estimated Hours End.
For calculating the Begin and End Hours we need to have some fields.The fields required for calculating the Begin and End are,
Initial Hour Meter,Adjusted Hour Meter,Fleet Management Date these three  fields are picked from the Equipment Master data for a particular Equipment and the Hour Meter Reading is the latest Meter Reading of the equipment it is populated from the Service Order or Notification which ever is latest in the date ange given by user.
There are some conditions in calculating the Hour Meter Reading Begin and End.
If the Fleet Management Date (Start-up Date on EM) started before the input date Date Range (From-Date), calculate the average usage (in hours) based on the initial hours and
If the Fleet Management Date started after the From-Date, use the Hour Meter (EM) as the Estimated Hours Begin. 
If the last PMN (or SO) fell short of the Date Range (To-Date), obtain the Estimated Hours End by applying the average usage to fill the time-gap. 
If the last PMN (or SO) fell after the Date Range (To-Date), get the Estimated Hours End by getting the next to last PMN performed inside the window parameter,
Adjusted Hours, if not zero or null, needs to be added to the Ending Hours to achieve the real number. 
The example for calculating the above requirement is below,
User Input Date Range:  Jan. 1, 2006 - Dec. 31, 2006     
Initial Hour (Equipment Master):  10     
Adjusted Hours (Equipment Master): 0     
Fleet Management Date (Equipment Master):  Dec. 1, 2005     
1st PM Notification (Feb. 1, 2006):  410     
Last PM Notification (Feb. 1, 2007):  2810     
Second to last PMN (Dec. 1, 2006):  2410
     Equipment was put into service (12/1/05) before the Date Range, needs to find the Estimated Hours Begin.
     The first PM was performed (2/1/06) exactly two months from in-service date (12/1/05).
     Average monthly usuage from first PMN = (410 - 10) / 2 = 200
     Estimated Hours Begin = 200 + 10 = 210 (estimated Hour Meter Reading on Jan. 1, 2006)
     Average monthly usuage from the last 2 PMN = (2810 - 2410) / 2 months = 200
     Estimated Hours End = 2410 + 200 + 0 (adjusted hours) = 2610 (estimated Hour Meter Reading on Dec. 31, 2006)
     Estimated Hours Total = 2610 - 210 = 2400
If you have any queries regarding the requirement just let me know i will let you know.
Thanks in advance
Bobby

Mahee,
We have maintained all personnel no of the employess working under a particular Maint.Work center in HRMS tab. Employee master data for all Infotypes are maintained in Personnel Management in HR module.  So wen the Employee enters Time details of his working hours per day, he has to mention the maintenance order Or it is like a standing order on the time sheet per line item. Wen transfer of working hours will be done on  a particular order the entire cost will be reflected in Cost tab page. Since me have maintained different Activity type/Activity price per employee I am confused about the flow of cost...
Ur suggestions were valuable.... hope to get some more clearity...
