Messages
Use
In order that the purchasing documents you create in the SAP System can be transmitted to the vendor (e.g. via the regular postal service as a normal printed document, as a fax, or via electronic data interchange (EDI)), the system generates a message for each document. (In this context, a message is a document in output format for communication to vendors, and should not be confused with system messages for example. The term "external message" may occasionally be used synonymously in this sense.)
The generation of messages is based on the condition technique, which is also used for price and account determination purposes. The condition technique is not discussed in detail in the following - it is assumed the reader is familiar with the fundamentals of this technique. For more information, refer to the section
Condition Technique and the Cross-Application Components documentation, section
CA - Message Control.
