Hi,
Perhaps an option can be created in DuplicateFilter that flags both the duplicate instead of keeping the first one on and moving the other one under the "Duplicates" button.
I am working with a topological network and there is one point where a duplicate feature could cause false connections later down the road. In a case like this, I would want to remove both and examine them later rather than FME choosing one over the other.
Right now I had to use ListBuilder--> List Element Counter --> Tester to remove it. Not the best way for something that should be simple.
For such an option I suggest the Input is ordered by group as well to make the transformation less blocking.Have you tried the Matcher transformer? I believe this can achieve what you need.
Thank you erik_jan, the Matcher transformer works perfectly for this purpose.
All the votes have been transferred into this idea.
