The user message trace functionality is used to output the contents of the messages flowing on the HCSC server to the user message trace file.

You can acquire the following items as user message traces:

• A service invocation request or response message received in the request reception
• A request or response message during the invocation of a business process
• A request or response message during the invocation of a service component from a service adapter
• A message before or after transformation when the data transformation is performed

By using the user message trace functionality, you can check that the messages flowing on the HCSC server are in accordance with the design. The smoothness of development will also improve because messages can be checked at each point (requester side and service side, BP activities, and data transformation).
