Filtering Fields from the Source Node

The Filter tab on a source node dialog box enables you to exclude fields from downstream operations based on your initial examination of the data. This is useful, for example, if there are duplicate fields in the data or if you are already familiar enough with the data to exclude irrelevant fields. Alternatively, you can add a separate Filter node later in the stream. The functionality is similar in both cases. See the topic Setting filtering options for more information.
