Help! I checked in old models over new models

     Our ME had finally finished up on all of our Models and assemblies.  Everything was checked into the PDM.  He then needed me to help him start generating part configurations for quite a few parts.  I pulled the latest stuff into my local working folder (I had older versions of parts and assemblies in the working folder) Well, of course these changes trickled up into the main assembly. In my haste to get out of the office, I checked everything back in.  Most all of my changes were to cable configurations. No actual new parts.  Each of our racks has a -0003 for hardware and a -0005 for wiring with everything rolling up into a -0001 for the rack.  I Checked in whatever Solidworks told me to, and I think the checking might have checked in more than I bargined for.  It seems to have affected or overwrote some of the later -0003 stuff and perhaps even part with olde parts.  Some of the assemblies are screwy.  The current model has some old stuff, and obsolete parts in it now.

IS there a way in the PDM to roll back the last checkin by a user?  If not, what is the safest way to carefully untangle this mess.

Thanks,

Tom
