Data Contribution to the Mediation Exchange

The Transform task can modify the message data within the mediation exchange, and contribute new data to the mediation exchange.

On the General tab of the Transform task, the checkbox labeled Contribute Output to Mediation Exchange specifies how the Transform task results are handled.

  • If Contribute Output to Mediation Exchange is cleared, the results of the transformation is used to construct a new message. This option is cleared by default.
  • If Contribute Output to Mediation Exchange is selected, the results of the Transform task are added to the mediation exchange as a new data element. The new data element is available to subsequent mediation tasks along the same path, and the name of the data element is the same as the name assigned to the Transform task.

The Contribute Output to Mediation Exchange option is automatically selected if you use an external stylesheet for data transformation. See External Stylesheets for Data Transformation.
