What happens if the size limit exceeds in a supplier communication email?

The total attachment size is set in the Maximum File Size Megabytes setting on the Configure Procurement Business Function page. The recommended setting is 5MB.

If the total attachment size exceeds this setting, the email will be sent with only the PDF so that the email size is below maximum size. Additionally, a notification will be sent to the buyer indicating that not all attachments were sent to the supplier.
