display content of any variable (especially CX_ROOT subclass instance)

Hello,

Do you know any FM or method to display the content of any variable? (elementary, deep structure, instance, ...) I can't know its type, except that it's an instance that is a subclass of CX_ROOT.

In fact, this question is related directly to my workflow question : when a class-based exception occurs, I serialize it into an XML string, and I'd like to display it on request (via business object methods) so that to help technicians. Of course, I know how to display any XML, but I'd prefer to use a specialized API.

Hope it's clear!

Thx

sandra

    Hi Sandra,

    I am not sure if this helps. But even if you are not aware of the subclass you can cast it (rather narrow cast) to the super class which in this case is CX_ROOT.

    • Hello Suhas,

      handling/catching exceptions is not the issue. Here is an example what happens: one of the possible exceptions is CX_SWF_RUN_WIM_DEF_FAILED.

      I know I can get the short exception text (and the long text if it exists), but it often doesn't give many details. For example:

      Exception CX_SWF_RUN_WIM_DEF_FAILED survenue (programme : CL_SWF_RUN_WIM_FACTORY========CP, include : CL_SWF_RUN_WIM_FACTORY========CM004, ligne : 239)

      I'd like to display its attributes, which could be (debugger view):

      CX_ROOT	                              
                CX_ROOT	16AA9A3937A9BB56E10000000A11447B
                TEXTID	16AA9A3937A9BB56E10000000A11447B
                PREVIOUS	{O:23*\CLASS=CX_SWF_RUN_WIM_DEF_READ_FAILED}
                KERNEL_ERRID	
                INTERNAL_SOURCE_POS	Structure: flat & not charlike
      CX_STATIC_CHECK
      CX_SWF_IFS_EXCEPTION	                              
                TIMESTAMP	0.0000000
                TIMEZONE	                              
                T100_MSG	WL    820E000000000003   WS90000001
                LOG_CONTEXT	Structure: deep
                EXCP_TAB	Standard Table[0x1(8)]
      CX_SWF_RUN_WIM	                              
                WI_ID	                     000000000003
                RETURN	Structure: flat & not charlike
                LOG_HANDLE	{O:25*\CLASS=CL_SWF_RUN_WIM_LOG}
                OBJECT_PRP	Structure: flat & charlike
      CX_SWF_RUN_WIM_DEF_FAILED
      

      They are very interesting because we see the true error message WL820 for example, which means: Work item 000000000003: Task WS90000001 cannot be read.

      Of course, there are many exception classes, it's why it should be dynamic.
