EB TAX ACCOUNTING - HELP NEEDED

 Hi,

I need some help on the tax accounting side.

There are many places to set-up a tax GL account in Oracle Receivables:

1) System Options

2) Transaction types

and now in ebtax you can assign a tax GL account at the 'Tax' level and also at the 'Tax Status Rate' level.

Can anyone explain how the tax GL accounting hierarchy works in Oracle 12 ? How does the system know which account to use ?

Is this something that we have to write SLA rules for or are there some standard Oracle functions to default the tax account onto Invoices?

At the moment we are getting a default account and I cannot locate where it is coming from.
