After a [line item is created](https://freewheel-knowledge-hub.atlassian.net/wiki/spaces/BC/pages/115507203), the system performs various checks to ensure proper delivery — defined as critical, severe, and moderate. With Line Item Doctor, notifications are sent when a line item does not pass one of these checks. The guide below explains each check the system provides and the possible issues that can be received. ## Critical Notifications Critical notifications are displayed in red and are the first check the system will do on a line item.
