Ans: Enhancements using customer exits:
Customers' potential requirements which are not included in the standard software are incorporated in the standard
as empty modification 'shells'. Customers can then fill these with their own coding. Enhancements can relate to
programs, menus and screens. Upward compatibility is assured. In other words, SAP guarantees that the jump from the
standard software to the exit and the interface which call the exit will remain valid in future releases.

Q15. How Do Sap Organizes Its Exits ?
Ans: SAP organizes its exits in packages that are called SAP enhancements. Each SAP enhancement can contain many individual exits.
Q16. What Is An Add-on Project ?
Ans: To take advantage of the exits available within standard R/3 applications, you need to create an add-on project.
This project lets you organize the enhancement packages and exits you want to use. The add-on project also allows you to hang add-on functionality onto the exit t hooks contained with SAP enhancements.
