Hi Rahul,
in Co19 there is start and end processing possible to post. So if you use this and mix it with a user exit which check that a pernr has start and end this should work.
But I think there is no standard function module for this. I don't know which user exit might be the best, there are CONFPPxx and the Badi workorder_confirm.
Hope this help.
