Most of our suppliers have integrated their delivery process by outsourcing the delivery to carriers companies.

As a result, when our orders are processed by the suppliers, we are notified by email:

• the supplier confirms that the order is processed and sends the corresponding invoice and custom information as 2 pdf attachments

• then their carrier confirms that they are processing the delivery and sends a link to their own system to allow us follow the status of such delivery

• 
  How is it possible to automatically link these messages and attachments to our own initial/source information lying with our Purchase order?
