Error when calling function module...

[aris_hidalgo]

Hello Experts,

I keep on getting the same error when I try to call my form. The error

is: 'Incorrect parameter with CALL FUNCTION.' I checked all the variables

and the tables that I pass but it is all correct. I compared it with the other

program that has a very similar logic and also calls the same form. But why is

this one gets an error?

Below is the routine:

PERFORM call_smartform.

FORM call_smartform.
  DATA: lv_control TYPE ssfctrlop,
        lv_options TYPE ssfcompop,
        ld_function TYPE rs38l_fnam.

Hi,

A Sample Program Calling Smartforms

REPORT  ZTACA_DRIVER_SMARTFORM                  .

Tables : sflight.
Data : fm_name TYPE rs38l_fnam.

*data : Begin of it_flttab occurs 0,
*        carrid type sflight-carrid,
*        connid type sflight-connid,

*        seatsmax type sflight-seatsmax,
*        seatsocc type sflight-seatsocc,
*        End of it_flttab.

data : it_flttab like table  of sflight.
Data : g_salary type i .
*       it_flttab type standard table of ty_flt.
g_salary = 1000.


select carrid connid fldate seatsmax seatsocc from sflight into
corresponding fields of table it_flttab.

Hi,

1) Check the TYPE's for each paramter

2) Try commenting one paramter at a time and execute, The paramter after commenting which solves the error is the culprit then you just need to find out the problem with that paramter.

Hi,

Vijay

Check it is most activated versioon of FM of Smartforms.

Otherwise Activate it again. Whcih will delete the log.

hi,

U should dynamically declare the function module name.

[Former Member]

Hi,

First you should make sure the SSF function interface is correct in your program. The best way to achieve it is:

In the Form Builder go to Environment -> Name of the function module

Copy the name of function module

In your program use 'Insert pattern' with the function name you copied from the smartform

Replace function name copied from the form with the variable ld_function, which holds the function name returned by SSF_FUNCTION_MODULE_NAME.

Make sure that the variables you are passing to the function module are the same type as interface parameters defined in the smartform.

Hello again guys,

Thank you for your replies. The reason why it keeps getting an error is that

I declared a new variable in my smartforms and forgot to tick the 'OPTIONAL'

checkbox so when I call the form, it requires the variable which I forgot to pass.

Again, thank you guys!
