SAP Transaction SE18 (Business Add-In: Definitions) is a transaction code used in SAP to create and maintain customer enhancements. It is commonly used by SAP consultants and developers to extend the functionality of standard SAP applications without modifying the core code. SE18 allows users to define, activate, and implement Business Add-Ins (BAdIs) that can be used to customize SAP applications to meet specific business requirements.

Step 2: Understanding SE18 Transaction Screen

Once you have accessed SE18, you will encounter the SE18 transaction screen, which consists of various fields and tabs. Let’s explore each of them:
