monthly production adjustments is not getting copied to tax book

Summary:

Hi

We have one corp and one tax book. The asset use units of production depreciation method in both corp and tax book. When we enter monthly production units in corp book, periodic mass copy process is copying the monthly production units to tax books and depreciation is getting calculated accordingly. However when change the monthly units in corp book for the same month, mass copy process doesn't copy the revised units of production for that month to tax book. The revised production amount is seen/visible only in corporate book. Is this the intended functionality? Please advise.
