How to view and monitor event messages in the Web Services Message Monitor.

Context

The status and content of messages sent from an event provider to a Web service can be monitored in the Web Services Message Monitor.

Individual event messages can be sent to more than one Web service ("subscribers"). Here, one or more child messages are sent to the respective Web services, based on the original parent message that originated from the event provider. The list of messages displayed in the Message Monitor contain:

  • Web service messages (Adapter Type is WS)
  • Parent event messages (Adapter Type is EVENT)

The status of a parent event message is Error if any of its corresponding child messages could not be created (usually because there is an error with the corresponding logical port). When an error does occur with an event parent message you have two options:

  • Correct the failed subscriber (logical port) in the configuration for the event provider, or
  • If the subscriber is no longer exists or applicable, remove the subscriber (see below).

You can take the following actions for event parent messages in the Message Monitor:

  • View the child messages/subscribers for the parent message.
  • Remove subscribers if the corresponding child message could not be created, in order to set the status of the parent message to Successfully processed.

Procedure

  1. Open the Web Services Message Monitor (transaction SRT_MONI).
  2. Use the selection screen to determine which messages to display.
  3. Select an event parent message that has an Error status.
    The messages here are the parent messages.
  4. Click the Display Event Subscribers icon.
    The list is displayed of the logical ports that the child messages were sent to (the so-called "subscribers"). If the status of the parent message is Error, this mean that one or more of the corresponding child messages could not be created.
  5. Remove the subscribers with errors.
    Select the messages with errors and choose the Remove Subscribers button. Alternatively, you can also select all messages (including ones without errors) and choose Remove Subscribers. The system will only remove those messages with errors. The status of the child messages is set to Removed.
  6. Close the Subscriber List dialog.
  7. Refresh the list of (parent) event messages.
    The status of the parent message is changed to Successful/Delivered.
