If you use this metric together with a campaign dimension, the values adhere to the default attribution.
Example:
A user views different pages and performs an order at 13:05 o'clock:
Days Analysis: At the corresponding day, one order has been tracked:
Pages Analysis: As the strongest scope between the dimension "Pages" and the metric "Qty Orders" is "Pages", the order is only counted for the order confirmation page.
You can adapt the metric scope, e.g., to "Visits". In this case all pages within the visit (cart, payment method, order confirmation) would have the value "1" for Qty Orders.
Example for using this metric in a filter:
Show only visits in which exactly one order was performed:
Show only data of users who did not perform an order in the analysis period:
