catch exception when interface method is not implemented

I have some interesting scenarios:

There is already a classic BADI and now a new method is to be added to the interface.

For the implementation class, they, for sure, don't implement the new method, however no syntax errors occur.Yet when runtime error 'CALL_METHOD_NOT_IMPLEMENTED' is raised when the new method is called via a variable of the interface.

CATCH SYSTEM-EXCEPTIONS CALL_METHOD_NOT_IMPLEMENTED = 4.

CALL METHOD g_badi->test.

* do nothing as customer don't necessarily implement the inteface

ENDCATCH.

Even I have try catch statement blocks surrounding the method call, the exception is still raised.

How can I handle it to catch the exception to avoid any short dumps?

Hi Xin,

Instead of catching SYSTEM-EXCEPTIONS try like below..

DATA : go_exception TYPE REF TO cx_sy_dyn_call_illegal_method, " Exception object
       gv_reason    TYPE string.                               " Reason for Exception


TRY.
 
    CALL METHOD g_badi->test.
 
  CATCH cx_sy_dyn_call_illegal_method INTO go_exception.
    gv_reason = go_exception->if_message~get_text( ).
    " gv_reason has the reason/cause for exception..
ENDTRY.

Cheers,

Jose.

HI, Jose

After I use the try catch block, the exception is still thrown out.

Are there any other ways to handle that?

Thanks

Xin

Hi Xin,

What does this ( 'exception is still thrown out' ) mean? a short-dump??

If yes, search for the raised exception object's type( starts with CX_ ) in the short-dump

and use that instead of cx_sy_dyn_call_illegal_method....

Coding like below is the most generic way and ll catch any class based exception.

TRY.
 
    CALL METHOD g_badi->test. " ur method call
 
  CATCH cx_root.
"Handler code.
ENDTRY.

If u r still getting a short-dump, then probably the exception is being raised somewhere else.......

Cheers,

Jose.
