Volume Overview 
This function contains all the usage-related information required to bill the service contract.
The system updates the volume overview by reading the counter values regularly. The system checks whether a reading is relevant for billing and, if so, assigns it to an entry in the volume overview. You can use Business Add-In (BAdI) Check Usage of Readings in Volume Overview to implement tests that the system performs when a new reading is received or the system has to determine the best reading for a billing period. This BAdI is located in Customizing for Customer Relationship Management under Usage-Based Billing (UBB) ® Record Usage ® Business Add-Ins (BAdIs) ® BAdI: Check Usage of Readings in Volume Overview.
If you have not entered a reading for a billing period yet, the reading and usage fields are blank. You can enter values manually. If you enter a relevant reading for this entry, the reading then overwrites your manual entries.
If no reading has taken place by a defined time, you can also use the UBB service contract to send reading reminders.
A copying machine has been installed at a customer site. It has two counters, one for black-and-white copies and one for color copies.
