type conflict while calling a function module

[former_member147217]

I am creating a candidate registration form .

When i a loading the registration view i have called the auto generated id function which i have created.

But while i execute i get this error.

METHOD wddoinit .

   DATA: count        TYPE i VALUE 0,

         wa_candidate TYPE zcanditate,

         value        TYPE char2  VALUE 'CN'.

   CLEAR : wa_candidate.

   " break-point.

   wa_candidate-zdate = sy-datum.

   CALL FUNCTION 'ZGET_NEXT_NUMBER'

     EXPORTING

       iv_object    = value

     IMPORTING

       es_studentid = wa_candidate

     EXCEPTIONS

       nonumber     = 1

       notfound     = 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.

*  SELECT COUNT(*) FROM zcanditate INTO count.

*

*  count = count + 1.

*  wa_candidate-candidate_id = count.

ENDMETHOD.

and the function that i have created is .

FUNCTION ZGET_NEXT_NUMBER.

*"----------------------------------------------------------------------

*"*"Local Interface:

*"  IMPORTING

*"----------------------------------------------------------------------

DATA: wa_zcadidate TYPE zcanditate.

IF sy-subrc EQ 0.

.

IF wa_zcadidate-candidate_id IS INITIAL.

wa_zcadidate-candidate_id = wa_zcadidate-from_number. ENDIF.

es_studentid = wa_zcadidate-candidate_id + 1. CONDENSE es_studentid.

wa_zcadidate-candidate_id = es_studentid.

IF wa_zcadidate-candidate_id LE wa_zcadidate-to_number.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT' EXPORTING

input  = wa_zcadidate-candidate_id

IMPORTING

output = wa_zcadidate-candidate_id. CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

EXPORTING

input  = es_studentid

IMPORTING

output = es_studentid.

UPDATE zcanditate FROM wa_zcadidate. ELSE.

RAISE nonumber.

ENDIF. ELSE.

RAISE notfound. ENDIF.

CALL FUNCTION 'DB_COMMIT'.

ENDFUNCTION.

I dont understand this error as i am new to this enviornment.

Hello Disha,

There are many standard function modules which will auto generate numbers.I think in your case you no need to go for custom function module.

Check this FM : PRGN_GET_NEXT_NUMBER_NEW

Otherwise,refer the following link.It will help you.

Calling Of FM

CALL FUNCTION 'ZGET_NEXT_NUMBER'

     EXPORTING

       iv_object    = value

     IMPORTING

       es_studentid = wa_candidate

this

wa_candidate TYPE zcanditate,

Error is... U are having exporting type in FM  ZSTUDENT_ID and Storing that data in wa_candidate which is TYPE zcanditate.

Got na?

Hi Disha,

     In Function Module, under importing parameter ES_STUDENTID is of type ZSTUDENT_ID. Whereas the parameter which you are passing to importing parameter wa_candidate is of type zcanditate.

Change the wa_candidate of type to ZSTUDENT_ID. And try to pass the value...

Hope it help to solve the issue.

Thanks,
