reFecth problem

reFecth problem

Hi,

I am importing data from Zoho Creator to Zoho Reports.  When I refetch the data, I have it configured so that it updates records already there and adds in new records.  The problem is, when I refetch the data, it is adding in both new and old records (ie I have 4 records, one was added, I now have 9).  is there something I am doing wrong

Kind Regards
