Source Code
Use
You use the Source Code tool to display the current source code of a program or screen in a back-end editor.
To display the Source Code tool by default every time you start the Debugger, from the Object Navigator, choose Utilities → Settings…. Under the ABAP Editor tab, choose the Editor tab and select Text Front-End Editor.
Features
● There is a variety of functions you can use to navigate through and examine the source code.
For more information, see Navigating through the Source Code.
● By double-clicking a data object, you transfer its current content to the Variables Fast Display tool. If the tool has not been part of the work area, it is displayed. If the work area already has the highest number of tools allowed, a dialog appears in which you can choose which tool you want to swap.
● By double-clicking outside a data object, you create a breakpoint in the Source Code Tool. If the line already had a breakpoint, the existing breakpoint is deactivated. Another double-click permanently deletes the breakpoint.
