Hello,
Im trying to fix a problem with sales invoices. Lately I got a problem that after a invoice is printed the second time anyone try to print it again the invoice got no lines in it.
The headers are always there except for invoice id every invoice printed more than once is called just invoice without id and any lines. In line section there is only info "No data is available".
Since it occours only for one customer group propably it's some custom code behind it but going back even a month with code didn't fixed it.
Trying to debug the standard salesinvoiceDP and salesinvoiceDPBase or my extended DP didn't trigger any breakpoint on this broken invoices on other customers it hits it and generate everything good.
Anyone good some ideas to try out here? The same problem is both on standard and custom invoice.
