For stage table data processing, suppose in first run we processed 8 records out of 10 records then in 2nd run we should consider only not processed records (here total no of records =2) along with new records which got loaded in stage table thru real time mapping. Note : In this example, 8 records are those records for which we got transaction number after lookup on trn_no_cod table and 2 records for which lookup returns trn_no as NULL
