Date track insert / Back Dated Global Deployment

 Gurus,

I am running into a situation, where i am required to do a date track global deployment.

Have 20 odds employees, that were piad in US bg for a day however were not entered in the system. Now HR wants to show that record in US BG - with same employee number, so that they can report to IRS that this employee came to us for a day.

Need to do temporary deployment like on 28-dec-2012,and receive this error when trying to intiate global deployment:

You cannot perform a DateTrack update where rows exist in the future Cause: The DateTrack update operation cannot be performed where rows exist in the future. Action: Consider performing a Datetrack Change Insert or Override operation.
