When you use the Siebel EIM Read transformation to extract data from EIM tables, the PowerCenter Integration Service writes the output status to the OUTPUT_STATUS port in the OUTPUT_STATUS group. The OUTPUT_STATUS port can contain the values 1 or 0. If the PowerCenter Integration Service extracts the data successfully, the value of the OUTPUT_STATUS port is set to 1. Otherwise, the value of the OUTPUT_STATUS port is set to 0.
