Hello, Tax Code question: we have some items for certain customers that should have a special tax code. But the issue is that i can only set one tax schedule on the item and one tax item on the customer. Is there a table somewhere in netsuite to tell: for this customer type buying this item type in this Nexus => set that specific tax code. ( but for all the other items, use the tax code define on the customer). thanks.

This sounds doable by using the tax schedule but not using the tax item in customer record. In a tax schedule, you can assign different tax codes per nexus.
