Hi Dirk,
Thanks for your reply. "You can easily get access at table level by using it as source in a dataflow. This works fine for extracting data from a single table. " I do not have experience on DS 4.2. Does the table refer to SAP Dictionary table or data base table? As I know, there is a RFC since DS 4.1. But it still extracts data from SAP ERP application table (first sap application connection, not database). Someone told me it is possible extracting data directly from database table on DS 4.2. Just wonder about it. Can you clear it for me? Thanks.
