# Discount Code Attribution Discount Code Mapping attribution is useful if you are advertising on mediums like podcasts that rely on promo codes for attribution. Your Discount Code Mapping BSD sheet allows you to specify which discount codes should be associated with which channels and vendors. Using these dimensions, you won't need to use complicated "discount code contains xyz" filters every time you want to analyze how much revenue a particular offline campaign generated. Instead, you just specify the rules once in your BSD sheet and then use the Discount Code Channel and Vendor dimensions during your analyses. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
