Which of the following statements about customer exits in SAP S/4HANA is true?

Customer exits in SAP S/4HANA are designed to allow businesses to enhance standard SAP functionality without modifying the original codebase. This means that using customer exits, organizations can implement additional features or alter existing processes to better fit their specific needs while still adhering to the upgrade and implementation standards of the SAP system.

This capability is crucial for companies that need to tailor their systems to comply with unique business requirements or processes while maintaining the integrity of the SAP environment. Customer exits are pre-defined points in the code where custom logic can be inserted, enabling a flexible approach to adapt the system.

The other statements do not accurately reflect the nature of customer exits. They are not restricted to the sales module and can be used across various SAP modules. Additionally, while custom software development may be involved for some enhancements, customer exits themselves do not necessarily require extensive development efforts. Lastly, they can be utilized multiple times and are not limited to a single use, providing a versatile solution for ongoing business adaptations.
