Wanna practice data lookup rules, follow these steps:

.Create a Data Lookup Table: This table will house the fields you want to match and the corresponding fields you want to auto-populate based on the matches. Think of it as a mapping guide. In our example, we'll call the fields containing the matching values "matches" and the fields to be auto-populated "setters."

.Configure Matching Choices: Within your data lookup table, configure the choices to match exactly with the choices available in your target field (in this case, your catalog item field).

.Define the Data Lookup in Your Catalog Item: Navigate to the Catalog Data Lookup Definitions section within your catalog item form or (System Policy > Data Lookup for regular tables).

.Create a New Lookup Definition: Specify the fields you created in your data lookup table within the new lookup definition.

.Set Matchers and Setters: Within the lookup definition form, define the "matchers" (fields containing matching values) and the "setters" (fields to be auto-populated).

.Prioritize Your Lookups: Data lookup rules are processed in a specific order. Access your data lookup table again and set an order for each record. This order dictates the sequence in which the records are processed, ensuring data flows smoothly.
