The PowerCenter Integration Service invokes an EIM task based on the value of the INPUT_STATUS port in the INPUT_STATUS group. The PowerCenter Integration Service does not invoke an EIM task if the value of this port is set to 0 or you do not connect a port that provides the input status to the INPUT_STATUS input port. If the value of the port is not set to any value set or to a value other than 0, the PowerCenter Integration Service invokes the EIM task.

When you use the Siebel EIM Invoker transformation in a mapping to invoke an EIM task, the INPUT_STATUS port receives the value from the first row of a source or from the output status of the previous transformation.
