[former_member219850]

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_DYN_CALL_PARAM_MISSING', was

  not caught and

therefore caused a runtime error.

The reason for the exception is:

When calling the function module "/1BCDWB/SF00000295", one of the parameters

needed according to the interface description was not specified.

This parameter was "IM_FS_KNA1".

The error is self-explained:

in your smartform ZSF_INVOICE  you have a mandatory parameter you are not trasmitting in the calling report.

Are you sure it's IM_FS_KNA1? The parameter IM_FS_KNA1 is declared like fs_kna1?

check types of FS_KNA1 & IM_FS_KNA1 in smartform, there would be a mismatch.

Hi Darshan,

You might have forgot to activate the smartform after adding the parameter.

You code seems work.

Hi,

Try pattern to eliminate parameter name problems.

Regards.

Maybe when you are doing your select from KNA1 nothing is being returned i.e.

SELECT SINGLE * 

           FROM kna1

           INTO fs_kna1

          WHERE kunnr EQ p_kunnr.

You should really check here that SUBRC = 0.

Activate your smartform, and delete the old function module call, call smartform again using function module name through pattern.
