Incorrect posting in asset accounting after legacy asset transfer

I have an issue in Asset accounting.

The depreciation key used is LINA (with a base method 0009 and Dec. bal. method – 001 straight line depreciation)

My question is:

An asset was acquired 02/01/2005. It has an expected useful life of 1/11.

Under AS93.

I see the asset cum. acquisition value 205,695.00

Accu.ord. deprec - 78,784.06

The asset was transferred to SAP at 03/31/2007.

Now In aw01n I see the following:

Legacy data transfer Per – 3 Ord. deprec – 10,143.87

Posted Per – 4 – 13,364.13

Posted 5 – 5877.00

Posted 6. 5877

Till 8th month posted 5877.

The posted values are wrong. Since it was transferred to SAP it has a useful life

of 1 year. At this rate it will go for 3 years.

What can I do to rectify this error?

Why is it posting 5877?

Thanks,
