How to reverse the Depreciation for the excess amount posted?

Question

Hi Gurus,
We have uploaded the data last month from legacy system to SAP as below.
The Fiscal year is Jan - Dec and gone live on June 28th 2009.
Accumulated Depreciation was taken till Dec 2008.
Ordinary Depreciation was taken from Jan 2009 to June 2009.
But Ordinary depreciation is not up to date in SAP as the user miss out the 2 months depreciation for each Asset but this was already posted in legacy system. All the GL Balances have been uploaded as per the legacy system. Now system is taking the previous 2 months Depreciation along with the current month. If we run the Depreciation for the current month, the system will post excess amount as it includes previous 2 months Depreciation.
Can any one kindly suggest the process to reverse the excess amount after Depreciation posted for the current month?
Thanks much for the help.
Early responses will be appreciated.
Best Regards,
JBC

HI
Few clarifications-
1. you have posted two months dep in legacy , have you transferred that dep amount wth the ordinary dep transferred from jan to june?
       If yes, that means your last posted dep month is june and accordingly you have to set the last period (6) in the SPRO for asset data transfer specifications, so system will start calculating dep from the 7th period only and will not recalculate dep for last two months.Check the last posted period mentioned in SPRO.
2.If you have uploaded wrongly your ordinary dep for current year , then that means your Asset accounting opening balance (migrated balance ) is not matching with your Trial GL upload as well, so you need to correct your asset accounting opening balances.
     For this you need to reset your company code status from 0 to blank ( tset data always allowed for asset data transfer). And then correct the values for current year ordinary dep posted from jan to june, also check the last posted dep period as above.
3.However you may post writeup ttype 700 to adjust the excess dep posted by any reason, you can extract last two months dep posted values asset wise from legacy system if already posted, and post the writeups for the same value in current period using LSMW.
