Hi Atul,
Unfortunately "Date" fields are not available in SAP standard BOR object BUS2000112. So you'll have to add them yourself as mentioned in the following OSS note (point 6):
And by the way: why do you generate 4, then 3, then 2... service orders at the same time? Why don't you use a condition that allows you to create a new service order every 3 months until the contract ends for example?
Regards,
Nicolas.
