The following settings are available in engage,
1. Sales reporting Date - The user will have the opportunity to select if the analytics report should consider completion date or creation date as the date for sales.
2. Order statuses - The user will have the opportunity to select the statuses that should be considered as a complete purchase. This will be used when training the models for product recommendations and displayed in sales reports.
Note: That some of the above settings requires a reload which means that you might not see the affect of the changes until the nightly job has been executed.
