Invoices created via Service Layer not sent by Print & Delivery

Hi everyone,

I’m currently using Print & Delivery in SAP Business One to automatically send invoices by email.

Invoices created directly within SAP are sent successfully. However, invoices created through a web application connected via the Service Layer are not being sent by email, even though the Print & Delivery configuration is already in place.

Has anyone encountered this issue before?
Is there any specific setting or limitation when documents are created via the Service Layer that could prevent Print & Delivery from triggering?

Thanks in advance for your help!
