How to Read Class or Object with Multiple Reference ??

 

 

 

 

 

1. We need to read the ZCX_EXCEPTION reference in the code.
2. zcx_exception TYPE REF TO lcx_exception.
3. DATA: exc    TYPE REF TO cx_root,
4. CATCH lcx_exception INTO zcx_exception.
   exc ?=  zcx_exception. " Take CX_ROOT INSTANCE
   
5. Above is the way to read CX_ROOT value in the ZCX_EXCEPTION to EXC reference.
6.  textid = exc-textid.
7. zcx_exception-text . Reading local class value.

Hi,

You can try to use do called dynamic text. First, convert your string to so called ITF Text, something like this:

DATA: l_string TYPE string,
      lt_stream_lines TYPE STANDARD TABLE OF string,

      gt_text TYPE tline_t .

CONCATENATE 'AAAA'
            cl_abap_char_utilities=>newline
            'BBBB'
            cl_abap_char_utilities=>cr_lf
            'CCCC'
            INTO l_string .
APPEND l_string TO lt_stream_lines .

CALL FUNCTION 'CONVERT_STREAM_TO_ITF_TEXT'
  EXPORTING
    stream_lines = lt_stream_lines
    lf           = 'X'
  TABLES
    itf_text     = gt_text.

Then, in the Smartform, set the Text node Type to dynamic text and assign the table with ITF Text:

You should get something like this:

This conversion is especially useful when you have to deal with strings longer than 255 characters (maximum variable output length in Smartforms).

The contents of the dynamic text will be parsed by Smartform Composer during runtime, so you can even include variables (the ones visible in Smartform context) in the string.
