Initial Mass Copy to Tax Book Accounting

Hi,

We have the following scenario.

1. Execute Initial mass copy
2. Execute tax update interface
3. Execute depreciation for the Perior
4. Create accounting
5. Review accounting for addition includes original costo, depreciation amount and expense in GL
6. Review accounting for adjustment includes changes to the cost and it reverse depreciation reserve and expense in GL
7. Review accounting for period depreciation include amount related to the reserve and expense in GL

There are not addition journal or lines for the new reserve amount.

My question is why the adjustment reverse the reserve and the expense and why the accounting does not generate a new journal entry for the new depreciation reserve, with that seems that initial balances for the asset is reverse and we only have the period reserve for the depreciation.
