Hi ​@shikoh.z , looks like there's a mismatch between the current Ataccama version UI and our training materials - thank you for the catch! We will update the labs.

Reference data could be stored either in a lookup file or a catalog item. If you want the rule to validate data against a lookup file that you've built earlier, then you're looking for the option "is not from lookup”. If you want to run validation against a column in a catalog item, then select "is not from catalog item”. Hope this helps!

Hi ​@shikoh.z ,

Thanks for bringing your question to the community! We've looked into your query about the 'Productline' field rules.

It seems you're currently working through the 14.5 training materials while accessing a 15.4 LTS environment. This difference in versions explains why you're seeing "is not from lookup" instead of "is not from reference data."

To ensure a smoother learning experience, we'd recommend aligning your training materials with the product version of your environment. Using 15.4 training resources on a 15.4 environment will eliminate any confusion caused by version discrepancies.

We hope this helps! If you have any further questions, please don't hesitate to ask. We're here to assist you.

Best regards
Danny
