Breakpoints in the New and Classic ABAP Debugger 
Setting and editing breakpoints in the new Debugger is almost identical to the Classic Debugger. However, several breakpoints can be set simultaneously in the new Debugger if you choose the path . Afterwards, the system displays a window in which the following options are available.

Here it is obvious that, in contrast to the classic Debugger, all the input fields –with the exception of those in the ABAP command tab –have a search help function (function key F4). For example, under the Method tab you enter a certain class. Then, in the search help, all the methods that belong to this class are proposed.
There are also certain differences when setting and deleting breakpoints. A double-click within a source code line creates a breakpoint in this line in both Debugger types, provided the cursor was not positioned on an ABAP keyword. A second double-click in the same line deletes this breakpoint in the classic Debugger, while it is only deactivated in the new Debugger.
