Mapping-Based Message Packaging 

Mapping-based message packaging is possible between the Integration Engine and the Adapter Engine. You can use it if n individual messages exist after a mapping-based 1:n split of the message payload. Prerequisite: All individual messages are being sent to the same Adapter Engine.

In message packaging, the individual messages resulting from the message split are not persisted individually, but grouped into a message package. This is then transferred to the Adapter Engine like a normal message. This saves time and resources in message transfer. The Adapter Engine then splits the bulk message up into the individual messages and persists them.

For performance reasons, you should not request acknowledgments for message packages since, in the case of a 1:n message split, this would result in n acknowledgment messages.

You have the following options for monitoring messages from message packaging:

●      Only messages packages are displayed in the monitor for processed messages in the Integration Engine. They are highlighted in the relevant column in the list of selected messages.

When you click a highlighted entry the system navigates to the monitor for message packages where you can then display the relevant individual messages.

In turn, the relevant message package is displayed when you enter the message ID of an individual message as your selection criterion in the monitor for processed messages.

●      Note that in message monitoring in the Runtime Workbench a distinction is made between the components Integration Engine and Adapter Engine.

○       In the Integration Engine only message packages are displayed. They are highlighted in the relevant column in the list of selected messages.

If you enter the message ID of a single message as your selection criterion, the corresponding bulk message is displayed.

○       In the Adapter Engine only individual messages are displayed but these are not recognizable as such. You can find out whether a message is an individual message or not by entering the ID of the message as the selection criterion for the Integration Engine. If there is a message package for this message,then this is displayed instead of the individual message you specified.

Conversely, if you enter the message ID of a message package as the selection criterion for an Adapter Engine, all the corresponding individual messages will be displayed.
