Which steps must you take to use a Business Add-in (BADI)?

To successfully utilize a Business Add-In (BADI), creating a BADI implementation is a crucial step. BADIs are a specific type of enhancement in SAP that allow developers to add custom functionality to standard SAP applications without modifying the original code. By creating the BADI implementation, you are essentially defining the specific behavior and logic that you want to inject into the BADI.

This step involves using transaction codes like SE18 to find the BADI definition and then SE19 to create the implementation. This implementation is where you specify how the BADI will behave in response to the business processes and the methods defined in the BADI interface. Writing the code for the methods, activating the enhancement project, and modifying the adapter class may also be part of the overall process, but they are not standalone primary actions necessary for utilizing a BADI. The creation of the BADI implementation is foundational, allowing the other steps to fit within a structured enhancement approach.
