I have one source table and three target tables. When the session runs for the first time involving the mapping,i want that the loading should take place in 1st Target table only. The 2nd time the same session runs the loading should take place in 2nd Target only only and similarly when the session runs for the 3rd time loading should take place in Third only. And again when the session runs for the 4th time loading should take place in 1st Target table.
