IU Transfer - period depreciation created for the BU/Assets that is transferred out

When the assets is transferred in May from BU1 (Transfer out) to BU2 ( Transfer in), why below 2& 3 happens:

1. Cost and Accumulated Depreciation are transferred from BU1 to BU2 - this is as expected.

2. Period depreciation entry is created for BU1 instead of BU2 in May and also not included in the accumulated depreciation for carrying forward to BU2 - this is wrong.

Is there any setting that controls the period depreciation to be created for BU2 ( Transfer in)?

3. Even the period depreciation is created for BU1 per DIST_LN, it is not reflected in the NBV on page Asset Management > Depreciation > Review Depreciation Infor > Depr Summary by Cost Type.
