Finding and Implementing SAP Customer Exits

SAP Customer Exit is a feature of SAP software that allows customers to add their own functionality to SAP programs without modifying the original source code. It provides a way to customize SAP software to meet specific business requirements without compromising the stability and integrity of the system.

Customer Exits are pre-defined locations within SAP programs where customers can add their own code. When the SAP program runs, it checks whether a customer exit exists at a specific point in the program, and if it does, the system calls the customer's own code to execute specific functionality. Customer Exit functionality can be developed using ABAP programming language, which is the programming language used in SAP.

By using SAP Customer Exit, customers can enhance standard SAP functionality, automate specific business processes, and integrate with third-party software. Examples of SAP Customer Exit functionality include adding custom fields to SAP transactions, modifying standard SAP reports, and integrating with external systems.

SAP provides a range of Customer Exits that are available for customers to use, as well as documentation and support for developing custom Customer Exit functionality. Using Customer Exit functionality allows customers to tailor SAP software to meet specific business needs and improve overall system efficiency.
