which integration channel do you use if your customer requests real-time transactional data synchronization between ERP and SAP Ariba buying and invoicing?
A . web services
B . File channel
C . SAP direct connectivity
D . EDI

Answer: A

Explanation:

Web Services is the integration channel you would use for real-time transactional data synchronization between ERP and SAP Ariba Buying and Invoicing. Web Services allow for real-time, two-way communication between systems, making them ideal for this kind of synchronization.

File Channel, SAP Direct Connectivity, and EDI are not typically used for real-time data synchronization. They are more commonly used for batch processing or other types of data integration that do not require real-time synchronization.
