odoo invoicing v18.0

similar in Odoo accounting v18.0

If I send an invoice by peppol, it shows in the comments what & when it has been sent, but there is no technical log of peppol. I hope there is one in the background or for the support guys, but it is not there for regular users.

We have an issue about attachements in an invoice. 

The invoice itself is embedded in the XML and is sent by peppol, but extra attachements seems to disappear. They are not received by the customer acess point, that is for sure.

It means all attachments have to be PDF and embedded in the invoice before sending by peppol.  f ex approuved timesheets, delivery notes, contracts,....

I just want to make sure which kind of attachment will be sent by peppol, if I could get my hands on the peppol logfile. 

I guess the support can retrieve this file or they might know the answer.

Kind Regards,

FHO
