Local Gaap and US Gaap treatment for assets in parallel

Hi,

I have the requirement of holding assets in both Local Gaap and US Gaap depreciation books for reporting and statutory purposes.

How can I handle this in FA? I know that for Tax Books (I don't require a Tax Book, I require a Local Gaap Book) we need to associate them to the Corporate Book and then create the additions for the Corporate Book and then is possible to run the periodic mass copy process to copy the additions from the Corporate Bookt to the Tax Book.

But what happen when having a Local Gaap and US Gaap depreciation book? Do I need to create the additions in each book? How is this usually implemented?
