Posting of entry based on inbuilt delivery days per customer.

The system automatically records the invoice released by the C&F Incharge based on the delivery time defined in the system for each customer. How do i check a configuration for this?

Eg: For a customer, the number of days for revenue recognition in XD03 is 5 days. As per the sale, the delivery has taken place on 22.07.2018 and accounting entry passed in the system was on 27.07.2018 i.e 5 days. How do I check the configuration in the backend?
