error in function module

[Former Member]

Hi,

I want to create a function module which adds two numbers

n1, n2 and should get the result n3 = n1 + n2. I tried creating the FM in the following way but i got error. Kindly rectify.

In the import parameters

parameter name typing associated type

N1 TYPE I

N2 TYPE I

export parameters

N3 TYPE I

Source code

FUNCTION ZY.

*"----

---

""Local Interface:

*" IMPORTING

*" VALUE(N1) TYPE I

*" VALUE(N2) TYPE I

*" EXPORTING

*" REFERENCE(N3) TYPE I

*"----

---

N3 = N1 + N2.

ENDFUNCTION.

regards,

mahathi

Hi,

while cresting fm after providing importing and exporting parameters in the source code write logic n3 = n1 + n2

and then call it in executable program

can you tell me what error you got...

See mahati,

jus put the flag for export parameter

i.e.enable the checkbox for pass by value in export parameter

this is the sample code

REPORT ZSYAM_F1.

parameters:a1 type i,

a2 type i.

data:a3 type i.

CALL FUNCTION 'ZSYAM_FM1'

EXPORTING

N1 = a1

N2 = a2

IMPORTING

N3 = a3

EXCEPTIONS

NOT_FOUND = 1

OTHERS = 2

.

IF SY-SUBRC <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

write:/ a3.
