Someone from SAP told me that :
"In US localisation the tax is depending
only on the delivery and good receipt location.The tax code will apply for all the item depending on the Business partner ship to address in case of a delivery and on the location of warehouse in case of goods
However, when i ask the end user from US, he told me that in one invoice, there are items which have GST, while other items on that invoice have PST + GST. Under this situation, the tax setting cannot be "generic" based on the ship-to-address. So, could anyone share with me:
1, How to deal with this tax issue on one invoice?
2, what's the general practice in US in the tax area?
