What tool is used for debugging ABAP programs in SAP?

The ABAP Debugger is the primary tool used for debugging ABAP programs in SAP. It provides a comprehensive environment where developers can monitor the execution of their programs in real-time. This tool allows users to set breakpoints, watch variables, and analyze the flow of execution line by line, making it easier to identify and fix issues in the code.

When using the ABAP Debugger, you can examine the state of the program at any point during execution, which is crucial for understanding complex logic or tracking down errors that occur during processing. Its features, such as the ability to interactively change the program's execution and inspect data objects, offer deep insights into how the ABAP code operates.

Other options, while related to SAP development, do not serve as dedicated tools for debugging ABAP programs. The SAP GUI is a graphical interface for users to interact with SAP systems, but it does not specifically focus on debugging functionality. The ABAP Workbench is an integrated development environment for ABAP programming, encompassing various tools for coding, but it doesn't directly provide debugging capabilities like the ABAP Debugger does. Lastly, transaction codes serve as shortcuts to access various functions within SAP, not specifically aimed at debugging programs.
