Debugging hindered by external development environment (see long text)

What causes this issue?

You are about to create an external breakpoint in the ABAP Editor. A
system check has shown, however, that external breakpoints coming from
another external development environment (for example, ABAP in Eclipse)
are also stored in the system under your user name.
Coexistence of external breakpoints that come from external development
environments and those that were created through the ABAP Workbench has
the result that the breakpoints interfere with each other and possibly
end up having no effect at all. This, in turn, can mean that the
Debugger will not be started in the desired manner.

System Response

How to fix this error?

To enable smooth debugging with the external breakpoints, ABAP Workbench
reset the activations of the breakpoints in the external development
environment. To prevent the external development environment from
setting the debugging activations again, it is best to disable the
debugger in the external settings.
