Which of the following options helps to identify source information in an Alteryx workflow?

The option that helps to identify source information in an Alteryx workflow is to use the "Output File Name as Field." This functionality allows users to keep track of the origin of the data being processed within the workflow. When this option is utilized, it creates a new field that carries the name of the output file, which can help in understanding which dataset is being worked with, especially when multiple datasets are used in a single workflow.

This feature enhances clarity and traceability throughout the data processing steps. For instance, if a workflow includes several input files and transformations, having an output file name as a field can be incredibly useful for auditing the results or debugging any issues that may arise. It clarifies where the data originated from, adding context that is crucial for data lineage and ensuring accuracy in analysis.

The other options, while useful in their own contexts, do not serve the specific purpose of identifying the source information as effectively. File format pertains to the structure and type of files being used but does not directly indicate source reference. Searching subdirectories is useful for locating files but does not maintain a reference to their origins in the workflow. The record limit restricts the number of records processed but does not inform about the source of the data.
