Function Module Parameters problem

former_member295881 — Thu, 27 Nov 2008 15:50:19 GMT

Hello Experts!

Iu2019m trying to write a PERFORM but having problems with its parameters.

The signature of the FORM / ENDFORM are as follows.

form SET_RETURN_MESSAGE USING VALUE(P_MESSAGE) LIKE MESSAGE

CHANGING P_RETURN LIKE BAPIRETURN.

Now Iu2019m not sure according to this FORM / ENDFORM how should I write my perform. As for now I wrote like this:

Perform SET_RETURN_MESSAGE.

And Iu2019m having error message about parameters saying:

Different number of parameters in FORM and PERFORM (routine:

SET_RETURN_MESSAGE, number of formal parameters: 2, number of actual

parameters: 0).

Iu2019m new with Function Modules and not sure how to provide the correct parameters:

Also it will be great if someone able to tell me how should I use these types u2018FMu2019, where Iu2019ve to pass the parameters.

Thanks.

Try this :

Option 1:

form SET_RETURN_MESSAGE USING VALUE(P_MESSAGE) LIKE MESSAGE

CHANGING P_RETURN LIKE BAPIRETURN.

endform.

Call you perform also with same number of parametre:

Perform SET_RETURN_MESSAGE using 'p_message'

changing i_return.

Option2:

form SET_RETURN_MESSAGE .

*Do your coding here with passing any parameters.

endform.

Call you perform also with same number of parametre:

Perform SET_RETURN_MESSAGE .

try this way this will remove the error...

Perform SET_RETURN_MESSAGE USING p_message

CHANGING p_return.

Hi,

As the error says..

U should have the same number of parameters from your perform to your form..

say :

data : hi type c value 1,

bye type c value 2.

perform write using hi bye.

then my form will have.

form hi1 bye1. "where hi1 = hi and bye1 = bye.

write : hi ,

bye.

endform.

your output wil be

1 2.

for ur scenario try as wat Avinash said....

One more to be added these are not FM's .

Pls check in se37 for FM's .

eg: GUI_download.

Thanks and Regards,

Sai

Hi Neha & Avinash,

Thanks for both of you for the quick reply. Iu2019ve tried both ways as you guys suggested:

Perform SET_RETURN_MESSAGE using 'p_message'

changing i_return.

Perform SET_RETURN_MESSAGE USING p_message

CHANGING p_return.

But looks like there is something wrong with the CHANGING parameter. It is complaing that u2018i_returnu2019 is unknown. Do Iu2019ve to define it in my top?

Once again here is the complete FORM/ENDFORM.

FORM set_return_message USING value(p_message) LIKE message

CHANGING value(p_return) LIKE bapireturn..

CHECK NOT message IS INITIAL.

CALL FUNCTION 'BALW_BAPIRETURN_GET'

EXPORTING

type = p_message-msgty

cl = p_message-msgid

number = p_message-msgno

par1 = p_message-msgv1

par2 = p_message-msgv2

par3 = p_message-msgv3

par4 = p_message-msgv4

LOG_NO = ' '
LOG_MSG_NO = ' '

IMPORTING

bapireturn = p_return

EXCEPTIONS

OTHERS = 1.

ENDFORM. " SET_RETURN_MESSAGE

HI,

Need to declare the i_returns in top include.

DATA : i_return type bapireturn.

Re: Function Module Parameters problem

Former Member — Thu, 27 Nov 2008 17:28:13 GMT

If I_RETURN is export paramenter of your fm, u should considere is not a global data, so it can't be seen in subroutine like a form.

Or u use a global data in order to transfer the value from subroutine to export parameter or you go to EDIT->INTERFACE->GLOBALIZE PARAMETERS

Hi Avinash,

Thank you & all others for such a great help. Iu2019m having just 1 last problem then looks like everything else is fine. Parameter p_return problem is been solved but p_message is creating problem. Iu2019ve tried it with 2 different ways and have 2 different types of error.

1st type:

Perform SET_RETURN_MESSAGE USING 'p_message'

CHANGING p_return.

ERROR:

Include LZAD_CO_BAPIF01

The literal "'p_message'" is not type-compatible with the formal

parameter "P_MESSAGE". -

2nd type:

Perform SET_RETURN_MESSAGE USING p_message

CHANGING p_return.

ERROR:

Include LZAD_CO_BAPIF01

In PERFORM or CALL FUNCTION "SET_RETURN_MESSAGE", the actual parameter "P_MESSAGE" is incompatible with the formal parameter "P_MESSAGE".

Re: Function Module Parameters problem

Former Member — Thu, 27 Nov 2008 17:50:23 GMT

HI,

FORM set_return_message USING value(p_message) LIKE message

CHANGING value(p_return) LIKE bapireturn..

You need to declare the p_message inthe top include with same type which you have provided in Form statement.
