Symptom:

Message no. SO865 (An error occurred during transmission – return code: <NF_ADR>) popups when using BCS to send emails.

Reason:

All the errors during BCS processing will be caught by cx_bcs and collected into BCS exceptions like the below:

data bcs_exception  type ref to cx_bcs.
Try.  
  catch cx_bcs into bcs_exception.
      message i865(so) with bcs_exception->error_type.
endtry.

Solutions:

If an email address-related error happens, it’s highly likely to occur during the call of cl_cam_address_bcs=>create_direct_address.

      call function 'SO_ADDRESS_ID_GET'
        exporting
          address             = i_address
          address_type        = i_addr_type
          no_intern           = l_no_intern
          no_adradmi          = l_no_adradmi
          usage               = l_pers_ref
          visname             = i_visname
        importing
          addrnumber          = l_addrnumber
          persnumber          = l_persnumber
          lfdnr               = l_consnumber
        exceptions
          address_not_found   = 1
          address_not_created = 2
          parameter_error     = 3
          x_error             = 4
          others              = 5.
      if sy-subrc <> 0.
        raise exception type cx_address_bcs
          exporting
            error_type = cx_address_bcs=>not_found.
      endif.

Run the Demo program ‘BCS_EXAMPLE_7’ with the email address list, and check whether the same error will occur or not.

• If yes then check & remove all the special characters including SPACE (besides _ -. @). If still not working, debug this function module ‘SO_ADDRESS_ID_GET’ and check the return value of exception numbers like ‘1’ for address not found.
• If not then debug how the email address has been fetched.
