Assign PO Smartform in NACE error-Processing routine does not exist

Question

I have created a Z-Smartform and Z-driverProgram and assigned both in NACE:
   Medium-           Program-                      Form-                                 PDF/Smartform-   Type
Print output-     ZSFPOREPORT-                          -ZSFPOREPORT- SmartForm
but a error message : Processing routine in program ZSFPOREPORT does not exist  ..
Do we need to code in driver prog under a Subroutine and call the same (or) Do we need to create a Form with Special Interface parameters similar to Entry_NEU ..
I am not sure as ENTRY_NEU is for a Script but we need to assign a SMARTFORM here...
So Gurus suggest.....

Hi
DATA:   fm_name  TYPE rs38l_fnam.
*-- Call the Smartform for Label Printing.
        CALL FUNCTION 'SSF_FUNCTION_MODULE_NAME'
          EXPORTING
            formname           = 'ZLS_XXXXX'
          IMPORTING
            fm_name            = fm_name
          EXCEPTIONS
            no_form            = 1
            no_function_module = 2
            OTHERS             = 3.
        IF sy-subrc <> 0.
          MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
                  WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
        ENDIF.
        CALL FUNCTION fm_name
          EXPORTING
            v_XXXX         = v_YYYYY
            v_matnr          = mara-matnr
          EXCEPTIONS
            formatting_error = 1
            internal_error   = 2
            send_error       = 3
            user_canceled    = 4
            OTHERS           = 5.
        IF sy-subrc <> 0.
          MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
                  WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
        ENDIF.
But this pattern is not same for all driver program. So you can do the following:
Step 1: Click on the area where you want to write function module.
Step 2: Click on "Pattern" at the top of the SAP window. Enter the function name as  SSF_FUNCTION_MODULE_NAME  and
             press ok.
Step 3: Now fill up the reqd fields. Give the name of the smartform in
             EXPORTING
            formname           = 'ZLS_XXXXX'
Step 4: Now go to the SMARTFORMS program Environment->Function Module Name  and copy  the Module Name.
            Again click on "Pattern" and paste the module name. Again you will get a pattern(i.e. the second function)
Step 5: Replace the Function module name with "fm_name" as shown in the code above.
Then your code is ready.
