AP Tax Accounting Question

Hi

Our client has the following scenario

- capture invoice in AP, select an account distribution on the line (Company.Account.CostCentre.Spare)

- select a tax classification code on the line

- when tax is calculated, they require that the liability account distribution that gets used is the natural account setup on the tax rate, and the cost centre chosen on the item line. There are more than 50 different cost centres, and we do not want to set up a tax rate per cost centre for every different rate.

Any ideas on how to achieve this requirement?

Thanks,

Kerry
