SDP update after DC scan

SDP update after DC scan

We have Desktop Central and Service Desk Plus integrated with each other.  I checked the integrated workflow and it says asset scan post immediately to SDP.  I was able to confirm this but one of the problems I noticed was that it doesn't update the OS on the machine.  

With the integration if something like an OS changes is it suppose to update the OS version showing in SDP?  If so, how do I fix it?

I worry that if I make other updates to my workstations (i.e. hardware upgrades) that it won't show in SDP which we use as our system of record.
