Hi @MiiKii ,
Welcome to the Oracle Analytics community and forum.
What is "Product Category Fiscal Classification Codes"? It sounds like some data you have in some application, is that the case? What is the product name?
If you ask about a Fusion application, you should go to the parallel CCC forum where Fusion products are covered: https://community.oracle.com/customerconnect
If it isn't Fusion, based on the product name you will provide it will be possible to move the question to the right category, or point you in the right direction of where to ask.
