I am just getting into PM. Here's my example :
Cycle is 7 days
Shift factor late : 25%
Tolerance ➕ : 10%
Shift factor early : 25%
Tolerance ➖ : 10%
Cycle modification factor : 1
Call horizon : 70%
Scheduling period : 28 days
Scheduling indicator : time selected
1st PM order created was 26.09.2008 ( manual call) for a starting fate 26.09.2008
2nd PM order is created on 01.10.2008 for a starting date 04.10.2008
Then first and 2nd orders have been completed 06.10.2008
3rd PM order is created on 10.10.2008 for a starting date 11.10.2008
4th PM order is created on 17.10.2008 for a starting date 18.10.2008
Can someone explain to me :
-for the 2nd PM order : why starting date is 04.10.2008? why creation date is 01.10.2008?
-for the 3rd PM order : why starting date is 11.10.2008? why creation date is 10.10.2008?
I can not figure out how the dates are determined ...
Thanks for your help !
