Most SD and MM process use Message Control. The concept of Message control is to generate and manage outputs from an application and control their timing and medium of exchange.  

Below are the details for configuring the message control and understanding how message control works.  

Configuring Message control: 

Message Control Components:  

Communication Structure:

 The communication structure passes application information to the Message control. The communication structure for output determination uses the naming convention as KOMxByy, where x can be K (header structure) or P (Item structure), and yy is two character application ID.

The two character application ID can be found from the NACE transaction depending on the application.  

The Procedure  

A Procedure defines a set of possible outputs for an application. A procedure is assigned a six character name. Several procedures can be defined for an application but only one can be configured as active.

A list of procedure can be seen in NACE transaction for the required application.  

A procedure has three main attributes:

- A List of output types – set of outputs that are possible for an application

- A Requirement field

- A manual flag  

Set of Outputs those are possible for applications are listed in the output types.  

Manual Flag is set if the output has to be selected by the user manually instead of selecting automatically.  

For Sales, Procedures can be assigned to Sales document type using V/43 transaction.  

Preconditions are captured in Requirements. These conditions are written in VOFM transaction.
