Hi Rudic,

I don't want to modify input data in csv file and don't want output in diff file
i just want to throw/print error for the rows where condition is not met in csv file

File should contain data in two columns in below given format.
and numbers in row and column may vary.
In short if column 2 contain row(1-2) with duplicate values(1234,1234) and column 3 should also contain duplicate values(4567,4567) in row(1-2)
and false condition will be when column 2 contain duplicate value(0808,0808,0808) where in row(1-3) but column 3 does not contain duplicate value(4567,4567,1234) in rows(1-3) , where column 3 contain 1234 in row 3 which causes this condition to be false

hope im clear now
Good condition
Code:
DT	DN	ON
CN	1234	4567
CN	1234	4567
CN	9876	6543
CN	9876	6543
CN	5678	4321
CN	5678	4321
CN	0909	3089
CN	0909	3089

False condition in "red"
Code:
DT   DN     ON
CN   0808  4567
CN   0808  4567
CN   0808  1234
