Message Listeners

You use a message listener server to receive data from another system using Message Services in SAP Manufacturing Integration and Intelligence (SAP MII).

Integration

You use message listeners for communication between plant, MES, and SAP ERP systems.

Prerequisites

You have already configured your message listeners in SAP NetWeaver Administrator.

For RFC communication, you configured an adapter with the name XMIIRFC[number]. You have created RTC destination. For details, see the section Creating an RFC Destination in Sending IDocs from the SAP ERP System to the SAP MII Message Listener.
For IDoc communication, you configured an adapter with the name XMIIDOC[number]. You have created and tested an Idoc connection in the SAP ERP system. For details, see Sending IDocs from the SAP ERP System to the SAP MII Message Listener.

For information about resource adapter configuration in SAP NetWeaver, see Viewing Resource Adapter Configuration in the SAP Library for SAP NetWeaver on the SAP Help Portal at http://help.sap.com.

Note Note

You must not change the Binding Key property in XMIIRFC and XMIIIDOC adapters in SAP NetWeaver Administrator.

Prior configuration for HTTP messages is not required.

End of the note.

Features

The SAP Java Resource Adapter (SAP JRA) server is used to connect to SAP ERP Central Component (SAP ECC) to receive remote function calls (RFC) and IDocs. You use the asynchronous HTTP interface to post data to SAP MII for asynchronous transaction processing.

On the Configuration tab page, you can assign a schema to the message listener. You can use the Link Editor to assign an XPath and dynamically create a message name. The system uses the message name to determine which processing rule handles the message.

Note Note

Similarly for EO support, you use the Link Editor to assign an XPath and dynamically create a Message UID.

End of the note.

To have the message listener queue and process an XML document, you post the XML document to the WSMessageListener service. The Name property maps to the Message Nameproperty in the Message Processing Rules screen. The MessageUID property determines the message duplication.

Post the XML document in the body of the message to the URL: http://<server>:<port>/XMII/Illuminator?service=WSMessageListener&mode=WSMessageListenerServer&NAME=<UniqueMessageName>

Note Note

You have to include MessageUID in the message for EO and EOIO support.

End of the note.

Activities

To access the list of message listeners, on the SAP MII administration menu, choose Message Services Message Listeners .

To confirm the connection for a selected message listener, select the Status tab page.
