Yearly Depreciation doubles

Dear Friends,

I would kindly need your help for the issue detailed below;

1. I create a new asset card from AS01. The useful life of the asset is set to 3 years.( depreciation key is normal which is supposed to calculate depreciation; by dividing purchase amount divided by useful life of the asset)
2. I buy the asset for 3k USD, from F-90. Asset allocates 1k depreciation for each year. But the depreciation still not posted.
3. I noticed there is something wrong with buying and I reverse the asset purchase document from AB08. After reversing, it shows no value in the asset card. So this is ok for me.
4. Then I purchase the asset again for 3k USD from F-90 by posting it to the same asset card.

As of the right after the step for is done, I expect the asset to allocate 1k USD depreciation for each year, but it doubles and calculate as 2k USD for each year and this is the issue now my customer faces.

I would highly appreciate any help,

kind regards,
