HI Vaddepati,

To best of my knowledge we can create the objects only in START-OF-SELECTION.

try it out.

Hi,

I dont see any problem with you code. I ran your code in my system and worked fine. Except for one thing that is you need to do a conversion exit on the w_vbeln before selecting data from VBAP in method load data. This is because when you ouput the data, the VBELN is converted to external format and thus needs to be converted to internal format if you want to do further selects based on it.


CLASS cl_vbap IMPLEMENTATION.
  METHOD load_data.

" Add this , so it converts the VBELN to internal format. 
    CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
      EXPORTING
        input  = w_vbeln
      IMPORTING
        output = w_vbeln.

    SELECT * FROM vbap INTO TABLE it_vbap WHERE vbeln = w_vbeln.
  ENDMETHOD. "load_data
  METHOD write_data.
    LOOP AT it_vbap INTO wa_vbap.

      WRITE : /5 wa_vbap-posnr,
      20 wa_vbap-matnr,
      35 wa_vbap-arktx,
      70 wa_vbap-netpr.

    ENDLOOP.

  ENDMETHOD. "write_data
