About Tax Records
In sales/parts orders, the tax records are created when each invoice is printed and
posted. These records are not altered, even if you change the transaction in A/R or
G/L.
If you enter invoices, credit memos or debit memos directly in A/R (not from sales/parts orders), the tax records are created based on the values in the special tax fields in the G/L distributions. When you post the manual transactions, the tax records are created.
