Dynamic Function Module call (Handling Table types)

Question

Hi Experts,
I am new to SAP NW RFC.
Actually I am developing a wrapper,which in fact an RFC enabled Function Module,which accepts a standard FM and its parameters. I am stuck up if the input parameters are associated with Table types.

Hi Rama,
Yes, I'm not passing value to the table parameter, but that parameter is where I want to retrieve data from FM, not pass value to, so I don't assign any value to ptab_line-value for that parameter.
BTW, I just did some test to pass value to the parameter using the following code and still got CALL_FUNCTION_PARM_MISSING exception:
FM: ZLEAD_CONTACT
parameters:
IMPORT:  I_PARTNER TYPE BUT000-PARTNER mandatory
TABLES: OT_CONT LIKE ZLEAD_INFO_S optional (here ZLEAD_INFO_S is a flat structure)
ptab_line-name = ls_import_para-PARAMETER.
ptab_line-kind = abap_func_tables.
create data ref_type type table of (ls_import_para-STRUCTURE).
ptab_line-tables_wa = ref_wa.
ptab_line-value = ref_type.
The detail of ptab:
VALUE
TABLES_WA
KIND
NAME
->2000000025
{A:initial}
10
2000000025
->Standard Table[0x10(588)]
->Structure: flat & not charlike
30
OT_CONT
And the same error if I set parameter using below code:
create data ref_wa type RS38L_TYP.
assign ref_wa->* to <fs>.
<fs> = ls_import_para-STRUCTURE.
ptab_line-tables_wa = ref_wa.
The detail of ptab:
VALUE
TABLES_WA
KIND
NAME
->2000000025
{A:initial}

2000000025
->Standard Table[0x10(588)]
