This will be a short guide on how to access source code-based of a class. Since classes are more common now, I’ll show this example on how to copy and paste / import codes directly into a class or backup into a local text file.
First, go to transaction code SE24 and input your class name.
Next, click Change and you will see screen below. Click Source Code-Based.
Screen below will be shown. You can either copy and paste codes from a text file into this code editor or import text file via Utilities → More Utilities → Upload/Download → Upload. Choose the text file with codes and click Open. You can backup the codes to a local text file via Utilities → More Utilities → Upload/Download → Download.
That’s all for this short guide.
