Thanks for looking at my post.

I have below calculated table formula. Issue is i dont want repeated numbers in the col1 but inspite of putting distinct there are few numbers getting repeated. Any idea please?

Thanks a lot

Table = DISTINCT(SELECTCOLUMNS(FILTER('table','table'[Column]='table'[RecDate]),"col1",'table'[PartNumber],"Comments",'table'[Comment],"Comment",'table'[RecDate],"Date",'table'[RecDate]))

Your format is taking the distinct combination of column1, comments and dates combined. So something like:

column1	comments	date
1	test	23/08/2023
1	test2	24/08/2023

are being counted as 2 different entries.

If you want to keep the latest entry per column 1 value, consider something like:

Table = FILTER ( 'TABLE', 'TABLE'[RecDate] = CALCULATE ( MAX ( 'TABLE'[RecDate] ), ALLEXCEPT ( TABLE, 'TABLE'[PartNumber] ) ) )

or consider how else you want to determine which of the duplicate values to keep.
