V2018 Sales Tax Reporting - Client currently reports sales taxes for two locations within VA. They have two tax reporting numbers. I know I could set up two tax codes/schedules but looking for an easier way to track sales tax by default warehouse code. So I am looking to put a UDF in the AR Sales Tax table to store the warehouse code. But I don't see a business object allowing me to populate the table. Am I looking in the wrong dark alley?
