First time copying of assets to tax book

We are on R12.2

One of our businesses has never mass copied to a tax book and 9 years later, they now want to do this. I see that the tax books were created in setup, but later made inactive.

These are the steps I would like to follow, but need some guidance on whether I am correct, or what I am missing please.

1. Remove the end date of the Tax Book
2. Run "Upload Tax Book Interface" concurrent process
3. Create SQL script to update assets in the fa_tax_interface table

Additional Questions:

1. How do I then upload the items on the interface table?
