Question

SLA update
I have an SLA for Proposals that use a ProposalSLADeadLine to control when this proposal will expire, but because a business rule issue the system has to update the SLA ad to do this I change the ProposalSLADeadline property with a new deadline date, but my SLA didn't obey this updated.
Do I have to do something more to the SLA? How does the SLA Agent know that I have updated the Date Property?
Where can I find some document to read how is the right way to manage this kind of thing?
Thanks
