Hi,
If I understand your requirement very well, for your use case is the expected result:
A B
1 10
2 20
3 30
4 40
The max value is 4?
Best regards

Hi Anugna,
Problem is interesting. I tried to make it bit difficult by changing the second column. Now my data is
A;B
1;10
2;5
3;30
4;20
And I want to display larger id is 3. Use tMemorizeRow component, set Row count to memorise for both columns to 2. Use tJavarow component and use the logic for identifying the maximum in Column B and set it to some context variable.
OnSubjobOk -- Print that context variable value.
See the attached screenshot for your reference.
Hope it helps
Thanks

Or, if this is coming from a DB, you could very simply use the max analytic function(s) to do it... For example http://stackoverflow.com/questions/6198320/how-to-use-partition-by-or-max
