Creation of Events via Message Control 
One of the options for customer-specific creation of events is fully integrated in Message Control. For this, you must create a separate output type and declare 9 (workflow event) as transmission medium.
This function is not available in a decoupled system.
Message control is used for the exchange of information between different partners.
Delivery System EVEN ("trigger event") has been created as output type.
The program RVNSWE01 with the form routine CREATE_EVENT is the standard processing program for sending the message.
The event ID and object type that describe the event created are assigned to a message application in the table NAST.
