Dynamic Function Module call with table parameter?
Hi All,
I'm trying to call FMs dynamically with PARAMETER-TABLE. These FMs are mainly about searching data from inputs and returning internal table as outputs. I managed to pass data into import parameters as query conditions, but still failed to set tables parameter. The code is like below, could you please help me check what's the problem? Thank you very much!!
data: lv_val type RS38L_TYP value 'ls_service_para-fmparam'.
data: lt_interface TYPE rsfbintfv,
ls_import_para TYPE rsfbpara,
ptab TYPE abap_func_parmbind_tab,
ptab_line TYPE abap_func_parmbind,
ref_wa type ref to data.
Field-symbols: <fs> type any,
CALL METHOD cl_fb_function_utility=>meth_get_interface
EXPORTING
im_name = LV_FM "FM name
IMPORTING
ex_interface = lt_interface
EXCEPTIONS
error_occured = 1
object_not_existing = 2
OTHERS = 3.
***loop IMPORT parameters and fill in data from lt_params***
loop at lt_interface-import into ls_import_para.
read table lt_params into ls_param with key key = ls_import_para-parameter. "check if exists query value
if sy-subrc = 0 and ls_param-value is not initial.
assign (lv_val) to <fs>.
<fs> = ls_param-value.
create data ref_wa type (ls_import_para-STRUCTURE).
assign ref_wa->* to <fs2>.
<fs2> = <fs>. UNASSIGN: <fs>,<fs2>.
ptab_line-name = ls_import_para-PARAMETER.
ptab_line-value = ref_wa.
ptab_line-kind = abap_func_exporting.
insert ptab_line into table ptab.
endif.
endloop.
***loop at TABLE parameters to retrieve data from FM***
loop at lt_interface-TABLES into ls_import_para.
create data ref_wa type (ls_import_para-STRUCTURE).
ptab_line-tables_wa = ref_wa. "set data type
ptab_line-name = ls_import_para-PARAMETER.
ptab_line-kind = abap_func_tables.
insert ptab_line into table ptab. "if commented, no exception occurs,but I cannot get any dataset.
endloop.
CALL FUNCTION LV_FM PARAMETER-TABLE ptab.
if I execute the code, when there has TABLES parameter defined in the FM, I get CX_SY_DYN_CALL_PARAM_MISSING exception with runtime error DATREF_NOT_ASSIGNED. But in debug mode, as shown in the screen shot attached, I did see the field TABLES_WA has correct type. So maybe I misunderstand the usage of PARAMETER-TABLE. Does anyone has experience on it?
Best Regards,
Jeff
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:

{A:initial}

->Standard Table[0x10(588)]
->Structure: flat & not charlike

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.

Dynamic Function Module call (Handling Table types)
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,
I need to call few function modules dynamically.The exporting and importing parameters are also known only at run time.
Can somebody help me out in this regard,
Thanks and regards,
Archnahi ,
Create Function module according to your requirment and call the same
such as
Create functi0n module where you are passing PLant runtime and get data related to Plant
write code in function according to requirment .
FUNCTION zrfc_test.
""Local interface:
*" IMPORTING
*" VALUE(ZWERKS) TYPE MARC-WERKS OPTIONAL
*" EXPORTING
*" VALUE(RETURN) LIKE BAPIRET2 STRUCTURE BAPIRET2
*" TABLES
*" ZIT_DATA STRUCTURE MARC
IF zwerks IS NOT INITIAL.
SELECT *
FROM marc
INTO CORRESPONDING FIELDS OF TABLE zit_data
WHERE werks = zwerks .
ELSE.
SELECT *
FROM marc
INTO CORRESPONDING FIELDS OF TABLE zit_data.
ENDIF.
IF sy-subrc = 0 .
MESSAGE ' Selected ' TYPE 'I' .
ENDIF.
ENDFUNCTION.
Suppose at runtime you get Plant 7100
types : begin of w_marc .
include structure marc .
types : end of w_marc .
data : it_data type standard table of w_marc with header line .
p_plant = 7100 .
Call to function module
CALL FUNCTION 'ZRFC_TEST'
EXPORTING
ZWERKS = 'p_plant
IMPORTING
RETURN =
TABLES
zit_data = it_data .
You will get result in it_data .
Note : if you don't know how to create Function Module then search on SDN you will get lots of Forum .

How to use function module together with tables in Crystal Report?
Dear all expert,
I have the following situation where I need to use a function module in my crystal report, But how can I link the FM with the tables so that I can pass out some value from the FM to the report?
Thank You.Hi,
Hope the following helps..
1)
LOOP AT IT_OUTPUT.
Call the function module to get the tracking number and store the output in the
variable V_TRACKINGNO.
IT_OUTPUT-TRACKING_NO = V_TRACKINGNO.
MODIFY IT_OUTPUT TRANSPORTING TRACKING_NO.
ENDLOOP.
2) Date conversion
DATA: V_CHAR(10) VALUE '2006.11.17'.
DATA: V_DATE TYPE SYDATUM.
CONCATENATE V_CHAR(4) V_CHAR5(2) V_CHAR8(2) INTO V_DATE.
WRITE: V_DATE TO V_CHAR MM/DD/YYYY.
WRITE: / 'MM/DD/YYY Format - ', V_CHAR.

But it saying : TABLES parameters are obsolete!
And I am not going further.
Please suggest any work arround.

now my first question is what is the difference between function modules calling normally and in the above said way
and the second question is
under tables parameter i have four internal tables defined where as while calling the same function module using recive results i have three internal tables. is this correct?
i am asking this because i am getting an error message while using this funciton module
please do not give generic answers, all the helpful answers will get a def rewardCall function starting new task is used to make Asynchronus RFC Call. In this case your function module will be called in a NEW SESSION and it will exceute independently from the Main program which is calling the FM. Also, the main program will continue its own processing and it will not wait for the RFC FM to complete.
Its not mandatory to have all the TABLES parameters in the RETURN Perform (..Receive results from ...) -
Getting values from a function module called in a WDA method
Friends,
I am trying to execute a function module from WDA.
I have created a service call for the function module. The function module takes values from the user, looks up the corresponding values of another field and returns the values in an internal table.
I am using the "Method Call in Used Controller" of WD Code wizard to call the function module.
When the event handler method containing the call to the function module is executed, nothing happens.
I am not sure how to pass values to the function module and to get the return values from the function module.
I am new to using function modules from WDA. Please help me out.
Thanks and Regards.Rashmi,
Is the function module intended to collect input data from the UI and process it? - Yes
If yes, then the input (importing parameter) to the Function Module is a table of values (which should be ideally from the context mapped to the Table UI Element). - The importing parameter is a single value NOT a table and is mapped to the view context.
Now this table UI Element is bound to the view controller context , which in turn is mapped to the component controller context. And you are indeed being able to read the value of this internal table in the component controller method where the function module is being called by means of get_static_attributes_table (Is this right? - Yes, I am able to read the table of values that is passed from the component controller view to form view context by using get_static_attributes_table.
Or are you being able to read it in the event handler method of the view controller and not being able to read it in the component controller method) -
The function module takes a single value as import parameter and returns a table of values as return value.
It works fine when no importing parameter is being used and returns the table of values that is getting passed from component controller context to form view context when i am able to read it using get_static_attributes_table.
Now the question is: how to pass the import parameter value to the function module. I assumed since the importing parameter is a context node (like the return values are), i should set the value ( captured when the user enters the value in the form) to the importing parameter context attribute using set_attribute method. Since it is mapped to the component controller context, i assumed it will get passed and the method will take it as input parameter.
Let me know if my assumptions are correct regarding passing the import parameters and what is missing here.
Thanks and Regards. -

Rfc function module call error
Hi Abaper,
I'm doing upgrade from 4.7 to ecc 6.0 currently and encounter problem in one of the rfc function module that we used. I've tested the connection to destination using sm59 and the connection is successful.
As an information, in the rfc setting, the target system is not Unicode system.
When I test using se37 and put the rfc destination in my function module call, I always encountered system_error exception. There's no issue with this rfc call before in 4.7 system.
Please help me on this. Thank you.
Edited by: Abraham Bukit on Sep 3, 2008 2:36 AMHi,
I had the same issue in the past and solved it in the following way.
If the destination system is not Unicode please try to set the password for the communication user set in SM59 using only upper-case characters and taking into account that the password shouldn't be longer than 8 characters.
Hope this will help. -
Error while using Function module SPELL_AMOUNT with arabic language AR
Hi ,
When i am trying to convert the number to words, using function module SPELL_AMOUNT with arabic language(AR),following abend message is coming and FM is getting abended.
Entry AR 0 1 in table T015Z does not have a delimiter (
Can you please provide me how to overcome this error?
Thanks & Regards
Seshagiri.Hi Santosh,
Thanks for quick inputs.
And amount is not having any delimitors.
I have checked in table T015Z and it has entries with AR as SPRAS.
All entries are having ':' at the beginning of the arabic words,and there is no single entry with ';'.
All entries with EN as SPRAS are having delimiters ';' at the end of the words.
Numbers are correctly converted to words in english,but abending in arabic.
Any idea please.
Thanks & Regards

Can a function module call another function module
Can a function module call another function module:-
within the same function group
(ii) within different function groupsHi,
We can call function from another function. If there is a function which is like a calculator and all the operations are from different functions then we have to call the functions from the calculator function for different functions.
If all the function are from same function group, Then the data is globally available to all the functions with in the group.
Otherwise we have to declare the data definitions for each of the functions if they are in different function groups.
Yes it is possible to call a function module from another function module:-
within the same function group
(ii) within different function groups

Check the inbound function module attached to process code in receiving system. Generally in every inbound function module first check is coded for checking message type or for checking funciton module like below.In the receiving system go to WE20 and then select the partner and select inbound message type. in that double click on assigned process code.then you have to double click on displayed FM. In that fm check first few lines. You will find this error message.
