In Customizing, you have specified that the user status ‘MLF’ (malfunction) is to be activated automatically in an operation, every time ‘00011’ (tool breakage) is entered as a reason for variance during a confirmation.

Now you assign a trigger point to operation 50. In the trigger point you specify via a workflow task that a mail is to be sent to a particular MRP controller, as soon as the user status ‘MLF’ is activated in the operation. If ‘00011’ is entered as a reason for variance when operation 40 is confirmed, the trigger point causes a mail to be sent to the MRP controller.
