One of our Advanced Reporting platform features, expressions, are used to define custom calculations and columns in reporting. We find expressions useful to pass in the proprietary data that you are not passing into the Facebook SDK or mobile measurement partner. This allows you to import in-app events or offline events and see the data in AdRules mapped to your Ad Set’s targeting.
To create an expression, select your data from the two columns and the mathematical operation between the two.
You may add, subtract, multiply or divide between the two columns.
