How to tax a TAX exempt customer or SHIPTO site irresepective of TAX EXEMPTION status of SHIPTO/Cust

Hi,

 

We have a requirement that the customer will be taxed for a specific product on sales orders.

However, tax should be calculated even if the customer or shipto site is defined as tax exempt.

 

scenario:

-----------------

 Customer and the SHIPTO is defined as tax exempt...but the BILLTO is taxable.

I have defined product fiscal classification setup based on item categories and Tax determining factors..When I create a manual invoice with SHIPTO as well as BILLTO with the product on the lines, then the tax is not calculated at all.

However, if i remove SHIPTO and just have BILLTO on the invoice, then the tax related to product applies correctly.
