exception class text use message class

[former_member609989]

Good day all. I have created a custom exception class which extends from CX_STATIC_CHECK. Under properties I specified a custom message class under general data in message class field. I want to display the text from the custom message class in the class texts when I throw a message as opposed to specifying the text directly in the class. How do I do that? Thanks in advance.

Is that what you're looking for ? Or could you clarify your question please?

TRY.
    ...
  CATCH zcx_... INTO DATA(exception).
    DATA(text) = exception->GET_TEXT( ).
ENDTRY.

Hi Sandra. Thanks very much for your help. I've created an exception class and specified a custom message class to be used with that class under properties. If I do this does it mean I don't have to specify any texts or text symbols in the class? Also...how do I throw the exception and specify the appropriate message id from the message class in the textid attribute on raising the exception?

You do not need to explicitly "reference" the message class you want to consume text from from the exception class. You specify the message at the time when the exception is thrown.

Given you created the exception class with flag With Message Class ticked syntax is

RAISE EXCEPTION TYPE zcx_test MESSAGE e001(zmessages) WITH 'This' 'is' 'a' 'test'.

(system release 7.52+) or

DATA textid TYPE scx_t100key.

textid-msgid = 'ZMESSAGES'.
textid-msgno = '001'.
textid-attr1 = 'This'.
textid-attr2 = 'is'.
textid-attr3 = 'a'.
textid-attr4 = 'test'.

RAISE EXCEPTION TYPE zcx_test
  EXPORTING
    textid = textid.

(also for lower releases)

The message class on the properties tab servers a different purpose.

endclass.




class zcx_blabla implementation.

    CALL METHOD super->constructor
      EXPORTING
        previous = previous.
 gv_parameter1 = iv_parameter1.
endmethod.
endclass.

to be able to push parameters to the exception class.

and when you will use it

raise exception type zcx_blabla 
exporting 
textid = zcx_blabla=>failed_to_...
iv_parameter1 = "whateveryouwant.
