Invoices created by processing backorders cannot be edited and saved. When trying to do this the error "Cannot add source backorder on lines for a new invoice" will be displayed.
Invoices can be picked and packed, and posted without editing. If editing is required, currently the invoice from the backorder will need to be duplicated to a new copy and the invoice from the backorder deleted.
