How Do You Change Sales Tax, Commission, or Freight General Ledger on a Company level to correct previous invoices that used the old general ledger?
Short Answer: Re-Process each invoice that contains the general ledger number.
Explanation: When you process an invoice, the general ledger accounts affected are pulled from the defaults in the tax resource, company setup, and/or the salesperson resource. You can process an invoice as many times as needed.
Therefore, once the general ledger account has been changed , you can go back in and process the invoice again and it will use the proper general ledger. To determine which invoices will need to be re-processed, run a list of general ledger transactions and sort (filter) by old general ledger number.
