Hi,
I just found out that I have duplicated "Non" and "Tax" exists in my SalesTaxCode database. Seems the last two which "ListID" has values are from QuickBooks, not sure what other two are from. However, it will show two "Non" and two "Tax" while user choosing tax code, so I have to remove one set.
The question is, I don't know which two my invoice item or sales items are using, if I delete those two sales tax code without "ListID", will it cause any trouble? Thanks.
Alex
