Metadata
There may be instances where you want to apply certain rules to aggregated data, such as applying a discount or adjusting values based on specific business rules. You can achieve this by using the Script function. If you need to reference metadata from aggregated sessions, such as the number of records or timestamps, you can access it using the meta-variable as described in Supported Variables/APIs.
