Adjust Invoice details - exported invoices eg SIDE
If an invoice has been exported in the daily close changes cannot be made directly on the invoice, it can only be opened in a "View" screen.
There are certain changes that can however be made to non-financial data. For example, the LEFT/RIGHT SIDE to which serial numbers are assigned can be updated.
The "Help" manual provides more information on this feature. Go to Utilities>Adjust Invoice details then open the help manual.
