The PowerCenter Integration Service extracts data from Siebel EIM tables based on the value of the INPUT_STATUS port in the INPUT_STATUS input group. The INPUT_STATUS port can contain the value 1 or 0. The PowerCenter Integration Service does not extract data from EIM tables if the value of this port is set to 0. If the value of the INPUT_STATUS port does not equal 0 or if this port is not linked, the PowerCenter Integration Service extracts data from EIM tables.
