Hello,

I am wondering if there is any chance to do some corrections on sales invoice from Sales. The user would like to change tax amount but we cant do it by using document type Sales correction or credit note because sales invoice is fully paid.

Any ideas are greatly appreciated

Hi,
With fully or partially paid invoices no sales coorections are allowed.
Now you can only do that from table maintenance, and tables that have to be dealt with are tfgld102/106 tfgld107/110 tfacr200.

The only other way to do it would be to issue a credit note to the customer and then re-do the invoice with the correct vat amount.
