PERIODIC MASS COPY ISSUE

Hi experts

I am facing the following issue:

- my corporate ledger have current period : Dec-2019, we creat another tax book which have Dec-2017 as a current period

- we did the initial mass copy, then periodic mass copy for dec-2017

with some assets which have adjustments in Dec-2017 we are facing issues as follow:

- if an asset has a original cost of 2000, and have 2 cost adjustments in Dec-17 let's say -300 and - 100, the initial copy create the asset in tax book with a cost of 1600 (2000-300-100) (instead of 2000). when we performe the periodic copy, the first adjustment is copied , so the new cost of the asset in tax book is : 1300 (1600-300).
