Initial Data Capture

For each Siebel transactional source table (S_) from which data is extracted, there is one S_ETL_I_IMG_ table and one S_ETL_R_IMG_ table.

The first time a staging table is extracted, rows that are in the specified period are selected and inserted into the appropriate S_ETL_R_IMG_ table. The specified period is set in the Prune Days parameter, in the Execution Plans tab. For more information about the Prune Days parameter, see About the DAC Execution Plans Tab.
