asset subsequent acquisition depreciation calculation value date is not considering

I have a query on Asset depreciation calculation in our
production system and need your help. Please find below Asset 1000735-09. On
29.02.2012 Acquisition Value 87,656/- added to this asset by AUC 2000509-08
transfer/capitalisation. Consequently depreciation per month of this asset is
increased to 737 per month from 172 till Jan 2012. We follow K4 (Jan – Dec)
Financial accounting period.

Query: when Asset capitalisation/ asset value date is
29.02.2012, why system is considering depreciation for Jan 2012 and adding to
Feb 2012 depreciation 1303 (bal Jan 566 + Feb 737= total 1303). It should
be considered only from Feb 2012 onwards.
