8) How can you debug a program in SAP ABAP?
You can debug a program in SAP ABAP by setting breakpoints, using the debugger tool (like /h for background debugging), and stepping through the code line by line to analyze the flow and values of variables.
9) What is a BADI (Business Add In) in SAP ABAP?
BADI is an enhancement technique in SAP ABAP that allows you to add additional functionalities to standard SAP applications without modifying the original code. It provides a standardized way to enhance the functionality of SAP applications.
10) Explain the concept of ALV grid and ALV list in SAP ABAP.
ALV grid is a powerful tool for displaying data in a tabular format with rich features like editable cells, column resizing, filtering, and more. On the other hand, ALV list is used for displaying data in a non editable tabular form with basic features.
