The New Debugger is a tool that helps technical consultants execute the program line by line or module by module. It stops the program to check the logic, identify errors, analyse the issue, understand the concept, etc. It has many more options compared to the old debugger. We will see some of the uncommon features that are helpful to the developers and functional consultants in their analysis.

If you want to analyse the program's data flow, then you need to debug the program. To enable or start the debugger, enter "/h" or "/H" in the command area of SAP.

Another way of activating debugging is to select the Debugging option from the menu, as shown in the below picture.

How to change the debugging session idle TIme

This time limit can be increased or decreased by using transaction RZ11. Enter the parameter rdisp/max_debug_lazy_time. This value can be changed as

Breakpoint skip(n) option

In the breakpoint tab, there is another useful option called Skip (Number).When we enter a number, we can skip that many records in one iteration within a particular loop.. end loop .

Since when has something that's been around for 20+ years been designated "new"?

I guess "new debugger options" is another way to say "(a few / backend) debugger options for abap newbies", although it's a completely-different meaning. "new things" is used when one thinks that the  audience doesn't know these things. If "new" is used in this forum, the author should expect remarks from experts of course.

Also I'm surprised to see that some people are still talking about the "old debugger" although it has been 99% deactivated since 7.40 / 10 years ago I think (1% = switch to the old via the hidden function code MAIN_OLD/or max sessions reached non-productively).
