I think we are talking about 2 different things.
We have 2 sub sales journals to charge tax in other provinces GST/PST or HST. I made a mistake and changed the parent journal and not the sub journals . Before I realized the mistake, we invoiced over 100 invoices. I do not want to have to edit every line from all those invoices if I do not have to. The only way I have found to do it is to, edit the quantity record it and the re-enter the qty and do this for every line on the invoice, or go to the tax column and enter item total * tax, and do this for every invoice.
Is there an easier way to recalculate taxs in existing invoices. In NV1 you just had to block invoices on the sales journal and run “TAXS”.
