A Simple Tax Update for France

Hi Folks,

I have been notified by my French accountant that France will get a new rate of tax sometime over the holidays.

A change to the default tax rate and the addition of a new tax rate.

Sounds simple - but now my Oracle nightmare begins.

We upgraded to R12 so no one has much experience of E Business tax.  Our tax codes were all upgraded, not entered in R12.

So I need to understand how to add the new rates in EBT, which is so counter intuitive I have tried twice and failed. 

Then I need to update 90% of our inventory items with the new tax codes.   Do I have to do this through the item API?  Anyone got any guidance on this?  Or is there a less technical way (other than manually updating every item individually).
