CX_ROOT Usage Check

What is the Intent of the Check?

This check searches for direct "CX_ROOT" exceptions being used in the code (e.g.: In a TRY-CATCH block).

How does the check work?

It search for the "direct" usage of CX_ROOT exceptions like:

Explicitly:

TRY.
  cls=>meth( ).
CATCH cx_root.   
  cl_demo_output=>display( 'Catching exception' ).
ENDTRY.

Implicitly:

CLASS cx_my_exception DEFINITION INHERITING FROM cx_root.
ENDCLASS.

How to solve the issue?

The solution is to use well defined and specific class-based exceptions.

What to do in case of exception?

In exceptional cases, you can suppress this finding by using the pseudo comment “#EC NEED_CX_ROOT which should be placed after the CATCH statement:

TRY.
  cls=>meth( ).
CATCH cx_root.   "#EC NEED_CX_ROOT
  cl_demo_output=>display( 'Catching exception' ).
ENDTRY.
