Hi guys,
I have data which look like this:
|ID|Number|
|1|1|
|1|3|
|2|1|
|3|1|
|3|2|
|3|3|
I need to group them by ID and pick up only rows with highest Number value. To get such data:
|ID|Number|
|1|3|
|2|1|
|3|3|
Any idea how to accomplish this?
Thanks

Sort by number in descending order and then a duplicate filter on the ID would also work. ID with highest number value would be output via Unique port
Here's one possible solution:
Am sure there are others.

It seems to work fine after fast check. Thanks

Seems simpler, didn't know about this highest value in duplicated filter funcianality.

+32You could also use a sorter to sort in descending order followed by the sampler with a group by on the ID field and a sampling rate of 1 with a sampling type of First N Features
I agree that the combination of a Sorter and a DuplcateFilter (or a Sampler) is a very elegant way, but there should be several ways as @david_r mentioned. These four ways flashed into my mind so far.
FYI.
