Fixed Assets

[Background]
The request to register assets directly in the tax book increases

[Details]
1 Manage Fixed Asset Lookups > Search for Lookup Types ORA_FA_ALLOW_TAX_SOURCE_LINES and ORA_FA_ALLOW_TAX_DIRECT_ADD > Enter Asset Book Name as Lookup Code
On the Edit 2 Book page, enable the following options:
Allow source lines
Allow adding direct assets.

→I wanted to perform the procedure number 2, and I saw the edit screen of the asset book, but the source line is grayed out, and the permission column for adding direct assets is not displayed.
How can we handle this?
