Hi all. I am pretty new to this language. I have a dataframe of 18col x 36k rows containing SKU data. Within this data there are Category and Subcategory columns. Then I have a second dataframe with the valid combinations of Category and Subcategory. What is the best approach for auditing the SKU dataframe to ensure that all Category and Subcategory pairs used are valid according to second dataframe master list? The second dataframe only has about 15 rows of data as it only contains the valid combinations.
Thank you!
Ted
