## Record Attribute Changes
This part keeps **track of changes to attributes**, like how many rows are there, how many are empty, the top values, and how many are different. It helps to notice and respond to changes in the reference data. In the Reference Data Unit (RDU), there's a table in the **Attribute Change** tab showing the history of attributes. This table records the first and last values for significant attribute changes, ensuring we always have information about data changes. Monitoring changes like row count, empty count, top values, and different counts helps spot changes in data features and behavior. This detailed tracking keeps data quality high and helps manage data effectively, like a history book for data. ### Quick Navigation The columns can be viewed and downloaded by applying sort, search, and filter options. * Sort - It helps in sorting from A→Z & Z→A * Search - It helps to locate specific information quickly * Filter - It helps populate search results by specific criteria ### Download Attribute Changes Download changed attribute lists for reference data units to access and analyze.
