Currently, it is only possible to define a single email address for all supplier and customer emails - statements, invoices, payment advices (remittances), CIS deduction statements, orders etc. However, in reality this varies on a supplier/customer basis and very often multiple email addresses are used for a single type of document.

It is possible to define this through configurations, but this is done in all implementations and all new prospects ask for this. Hence, more flexibility should be allowed in the Comm Method tabs or in report rules to select multiple types of comm method lines. 

It is very typical for different customers and suppliers have different setup requirements. E.g. for some suppliers/customers, the statements will be sent to a single email address, but for others it will go to multiple email addresses. 

The solution could be to introduce multiple generic checkboxes for “Report Type X” against the comm method tab:

This allows for flexibility, because these can be renamed through page designer as part of implementation to mean different things for different customers.

The next step would then  be to allow the use of “Report Type X” in the event actions to send an email for each type of document to all the email addresses associated with the “Report Type X”. 

This would allow for upgrades as customers can continue using their current setup, but also add additional flexibility to define multiple records to email documents to.
