To be able to re-issue an invoice with the same invoice number you may need to change some settings and screen layouts to allow you to do this.
By default, Attaché is set up not to allow duplicate invoices and is also set up to allocate the next invoice number automatically.
Note: If you make the following changes to keep one customer happy you may want to change them back when you complete the transaction.
You will need to be a system administrator with access rights to be able to make the changes. If you don't have the required access, then have someone on your site with the required access make the changes.
To change the settings to re-issue an invoice, follow the steps below:
Go to Setups, Customers, Options, Invoicing Options.
Make sure that Allow duplicate Invoice Numbers is selected.
Accept (F9) any changes.
Go To Setups, Customers, Screen Designer, Invoices.
Click on the Invoice Number data field in the header and select to Modify (F5).
Set the Field Status in the Invoice Number data field to Edit.
Accept (F9) the Invoice header.
Zoom In (F3) to the header and make sure the Invoice Number data field is also set to Edit as above.
Save (F7) any changes you have made.
Create your new invoice and remember to enter the Invoice Number you are wanting to reissue in the Invoice Header prior to accepting the invoice.
Reverse any changes you have made above if this was a one-off invoice reissue to reduce the possibility of invoice duplication in the future.
