What is the "Fraud Detection — changes after approval" setting? (Cin7 Core)

ApprovalMax tracks all changes that are made to a finance document in Cin7 Core after the document has been approved in ApprovalMax.
This includes Organisation-wide changes such as Suppliers, Categories or Locations. 
ApprovalMax enables Administrators to configure which changes will be tracked (see screenshot for reference). For example, it can be specified that a change of Category won’t be tracked while any change of the amount will.
This feature can be configured by clicking on the icon in the Purchase Order approval workflow:


If a change occurs in Cin7 Core, a notification email is sent to the Organisation Administrators to make them aware of it. 
Please note: changes are tracked and will trigger a notification, even if it’s not visible in the history of specific documents.
To see the detailed history of the changes made (i.e. both the previous and the new value), you need to open the ApprovalMax audit report and take note of the previous value, before checking it against the new value in Cin7 Core.
