Invoices not being generated

Good afternoon,

We have the issue that (seemingly random) some accounts do not generate an invoice when it should.
Unfortunately I am unbale to find any logic in this issue, it happens:

  • to both Vendor and Customer invoices
  • invoices of 0.00 EUR as well as any other amount
  • different accounts each time
  • new accounts (< 1 month of age) as well as older accounts

I’ve looked through the logs at /var/log/yeti (yeti-cdr-billing, yeti-management and yeti-web) but am unable to find any entries related to invoicing.
Is there another log where I can find more information regarding invoice processing?

Thank you,
