How can I debug my Alteryx workflow? How to debug your Alteryx Workflow If you are getting errors, or answers that don’t look right here are some strategies for digging into your workflow to find out what is going on. Add a Select Tool Place it before the tool with the errors to see if the data is in the proper format. The Alteryx website has resources that allow you to see what type of data each tool expects: If you renamed a field use a “_” instead of a space between words. Watch out for certain tools that might change the title of a field like the summarize tool or score tool. Add a Field Summary Tool Use the Field Summary tool followed by the Browse tool to investigate the distribution of a field in detail. Add a Data Cleansing Tool Small things like trailing or leading whitespace can cause errors in many tools. Null values cause errors in many tools, use a data cleansing tool to replace nulls with 0s, you could also use a Formula tool or Imputation tool to help replace nulls with other values depending on the scenario. Look at the Original Data In your cleanup process, you might have accidentally deleted some of your data. Check out what the data looked like when you input it to see if there is data that does not make it all the way through the workflow. Add Browse Tools Put them everywhere, see where your data changes. Many times there will be a small mistake somewhere in the flow and browse tools are your way of taking a peek at all steps of the workflow. Review the project details, supporting material, and rubric A helpful step is reviewing carefully the project details as they sometimes specify how to configure certain tools in the analysis.
