Which attribute can be used to locate written data downstream of a FeatureWriter?

• A. _destination_path
• B. _filepath
• C. _dataset
• D. _output

Answer: (C)

In FME, writers attach a system attribute to features that identifies where they were written. The attribute that carries the destination dataset for each feature is _dataset. It holds the dataset name or identifier used by the writer, and downstream transformers can read it to locate the written data, enabling destination-aware processing, validation, or routing. Other attributes may contain path-like information in some contexts, but they aren’t the universal reference for the destination dataset, so _dataset is the reliable field to use.
