Need Clarification on Lists Permissions for Account Registers

When customizing a role, the Lists tab offers permissions for a number of account registers, like:
[LIST]
[*]Accounts Payable Register
[*]Accounts Receivable Register
[*]Bank Account Registers
[*]COGS Registers
[*]Expense Registers
[*]Fixed Asset Registers
[*]Non Posting Registers
[*]etc[/LIST]So, the questions is do you need to give "EDIT" permissions to these accounts in order write to the account using any of the standard processes in NetSuite, like Invoicing, Customer payments, Pay Bills, etc.

IOW, exactly what is the purpose of giving or denying permission to these registers in the List tab?

Thanks.
