Asset retirement -Accumulated depreciation

Dear All,

Am retiring the asset in februay 2012 using the transaction type 209, which has current net book value 1326.26 ,Acquistion value 3563.13(Acqistion Year :2007,June),accumulated depreciation 2276.46(which includes Jan 2012 depreciation 39.59).

When I simulate , the entries are the below appearing.

Acquistion Value 3563.13 (Cr)

Accumulated depreciation 2236.87(Dr)

Gain/Loss 1326.26 (Dr)

We want the accumulated deprecation should be debited with 2276.46 (2236.87+ Jan 2012 dep amnt 39.59).

Could some one tell why system is not including the jan 2012 depreciation in Accumulaed depreciation.Please let me know is there any way I can tackle this.

Thanks,
