>Every now and again I am asked to take a look for duplicates in t table. I would like to be able to set a filter to something so that I only see duplcates in the browse window on a particular fields. Set filter blows up things so if there is another way, please forward it. Thanks

You can
1. select key fields of the duplicate records into cursor.
2. set relation to this cursor from your table
3. Browse the table using this relation

SELECT orgtracnum, date, amount, bankname, count(*) as CntDupRecss ;
  FROM mytable ;
  GROUP BY 1,2,3,4 ;
  HAVING CntDupRecss > 1
  INTO CURSOR crsDupRecss 

INDEX ON orgtracnum + DTOS(date) + STR( amount, 10,2) +  bankname

SELECT mytable
SET RELATION TO orgtracnum + DTOS(date) + STR( amount, 10,2) +  bankname ;
    INTO crsDupRecss 

BROWSE FOR FOUND("crsDupRecss")
