  TRY.
      SEND_REQUEST = CL_BCS=>CREATE_PERSISTENT( ).
      LP_PDF_SIZE = XSTRLEN( STRING ).
      PDF_CONTENT = CL_DOCUMENT_BCS=>XSTRING_TO_SOLIX(
          IP_XSTRING = STRING ).    
    CATCH CX_BCS INTO BCS_EXCEPTION.
      RETURN-TYPE = 'E'.
      RETURN-MESSAGE = BCS_EXCEPTION->ERROR_TYPE.
      APPEND RETURN.
      EXIT.
  ENDTRY.
  DOCUMENT = CL_DOCUMENT_BCS=>CREATE_DOCUMENT(
        I_TYPE    = 'RAW'
        I_TEXT    = L_BODY
           i_hex     = pdf_content
           i_length  = lp_pdf_size
        I_SUBJECT = 'test' ).    
  CALL METHOD DOCUMENT->ADD_ATTACHMENT
    EXPORTING
      I_ATTACHMENT_TYPE    = L_EXTENSION
      I_ATTACHMENT_SUBJECT = 'test''
      I_ATTACHMENT_SIZE    = LP_PDF_SIZE
      I_ATT_CONTENT_HEX    = PDF_CONTENT.
  SEND_REQUEST->SET_DOCUMENT( DOCUMENT ).
  RECIPIENT = CL_CAM_ADDRESS_BCS=>CREATE_INTERNET_ADDRESS(
      I_ADDRESS_STRING = 'emailid'' ).
  SEND_REQUEST->ADD_RECIPIENT( I_RECIPIENT = RECIPIENT
                               I_EXPRESS = ' '
                               I_COPY = ' '
                               I_BLIND_COPY = ' '
                               I_NO_FORWARD = ' ' ).
  SENT_TO_ALL = SEND_REQUEST->SEND(
