Discussion moved from Community Interface Help to ePolicy Orchestrator (ePO) for better attention.
I believe that you have query about SDAT which has DAT and Engine in it and you want to check in to the ePO server and deploy to the client machine.
Surely you can. Please download SDAT package from #: http://www.mcafee.com/apps/downloads/security-updates/security-updates.aspx?regi on=us and select th ePO compatible SDAT. The file name will be 'SuperDAT Package For Use with McAfee ePO'.
