Need setup ebTax as 11i

 Hi

My customer needs for a short time to define ebtax rules running as in 11i. This is R12 fresh install and for at least 2 years they only use it for Manufacturing and Purchasing ( financials will continue in 11i).

So they need to define Suppliers in R12 and associate the tax classifications code and they don't want to use at this point ebtax rules, jus derive tax rates through application hierarchy.

Do you know if is possible?? and if is, how do we have to setup ebtax?

Thanks
