What we have seen during FAW upgrade column W$UPATE_DATE gets updated for the entire dataset, we are using this column as the indicator for incremental data update while pulling data from FAW. During upgrade entire data set (records in millions) becomes qualify for incremental data pull. Can you suggest what column should be referenced which qualifies the incremental data? For example in tables dw_gl_journal_cf, dw_gl_balance_cf.
