Hi ​@Vaishali , dq rules in Ataccama ONE usually work on the row basis - rule condition would usually evaluate the column values in specific row of data. You can build aggregated rules that would compare specific row of data with aggregated data in the dataset but you need to have a clear idea how you would aggregate it based on what exactly you’re trying to see in the result.

Could you please clarify what is the final goal of the rule?
Do you need to compare the values only between specific categories or between all of them (basically identifying the maximum)?
Thank you!
Ivan

Thanks ​@ivan.kozlov for your response.

I am not looking for aggregate values. I want to compare some of the categories with each other. The comparison may be checking values less than or greater than each other. Or it can be checking if value of category B is x times value of category A.

Unfortunately i don’t think what you’re trying to do is possible especially using only rules created in webapp UI. For rule condition to be evaluated, all the input attributes should be withing the same row of data and the data you need for your rule will never be in one place unless the catalog item structure would look completely different (values for A, B, C, D that have to be compared would be in the same row).
