Is it possible to create a Functional module dynamically?

Hello All,
Does any one know whether is it possible to create a FM dynamically and write some code in it?
Regards,
Lisa.

Hi,
Yes it is possible.
Use this FM to create a function module on the fly programatically.
RS_FUNCTIONMODULE_INSERT.
Here is an example
Here an example how to call it:
call function 'RS_FUNCTIONMODULE_INSERT'
exporting
funcname                      = '/TEST40P/FB_TEST_EVE99'
    function_pool                 = 'CRAS1'
*   INTERFACE_GLOBAL              = ' '
*   REMOTE_CALL                   = ' '
    short_text                    = 'TEST Anlage FB'
   suppress_corr_check           = ' '                -----------------> means with transport popup
   update_task                   = '1'
*   corrnum                       = 'B20K8A0V3F'
   namespace                     = '/TEST40P/'
*   suppress_language_check       = 'X'
*   AUTHORITY_CHECK               = 'X'
*    save_active                   = ' '
    new_source                    = it_report[]
* IMPORTING
*   FUNCTION_INCLUDE              =
*   CORRNUM_E                     =
tables
import_parameter              = if_import
   export_parameter              = if_export
   tables_parameter              = if_tables
   changing_parameter            = if_change
   exception_list                = if_except
   parameter_docu                = if_docu_tab
*   SOURCE                        =

Calling Function Modules Dynamically

Hi All,
Is it possible to call a function module dynamically i.e. to pass the module name and the import and export parameters dynamically at runtime. Please provide a way of achieving this.
Regards,
Milan Thaker

Hello,
Read this SAP documentation on calling function modules dynamically: [http://help.sap.com/abapdocu_70/en/ABAPCALL_FUNCTION_DYNAMIC.htm|http://help.sap.com/abapdocu_70/en/ABAPCALL_FUNCTION_DYNAMIC.htm] Here you have an example explaining the technique.
Also check this link on [ABAP FAQs|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/840ad679-0601-0010-cd8e-9989fd650822#q-29].

IIs it possible to retrive deleted Function Module

Hi all,
i just want to know is it possible to retrive deleted Function Module .
the request is not released yet.

Hi Sai,
Its not possible. (Confirm by contacting ur Basis people, if they can help).
But the following is valid only if your function module is(or was) a transportable object.
Go to SE37, enter your function module name and create. Assign it to the same function group and have the same interface and description. Save it, activate it.
Now go back to SE37, enter the function module name, in the menu, 'Utilities>Versions>Version Management'. Now you should see all your previous versions. Select the most recent past version. Do a retrieve and then activate it as the latest version.
Not sure if it works. But still give it a try.
Best Regards,
Anjali

I want to create a function module.
the following is my requirement.
by passing(eporting parameters to funtion module from pgm point of view) a field, i want to get(importing parameters from the funtion module, from pgm point of view) some 7 fields(of various tables).
please also tell me how can code an inner join for tables 5 tables(a,b,c,d,e). i'm joining a on b, b on c, c on d,the problem here is that i can not join d on e as there are no common fields in d and e.

How to create RFC function module and how to call this function module

Hi,
i want to know step for creating RFC function module and then How to use this function module from some other sap system.
Thnaks,
jigar

Jigar,
To implement a remote function module in ABAP, perform the following steps:
Register the module as remotely callable in the RFC server system.
In the function module Administration screen (transaction code SE37), set the field Can be called via REMOTE CALL. Registering a module as remote causes an RFC stub to be generated for it.
Write the code for the function module.
Create the destinations.....................
Displaying, Maintaining and Testing Destinations
To display, create or modify destinations, choose Tools ® Administration ® Administration ® Network ® RFC destinations or enter transaction code SM59.
Remote Destinations are stored in table RFCDES. The RFCDES table describes logical destinations for remote function calls.
It is not possible to maintain the RFCDES table directly.
You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® AcceleratedSAP ® Customizing ® Execute Project ® SAP Reference IMG.
In the Implementation Guide, expand the following hierarchy structure:
Basis
Application Link Enabling (ALE)
Sending and Receiving Systems
Systems in Network
Define Target Systems for RFC Calls
Displaying Destinations
The initial screen for this transaction displays a tree:
Different connection types (i.e. partner systems or programs) are possible. For further information, see Types of Destinations.
To display all information for a given destination, double-click it, or place the cursor on it and press F2 .
To search for a destination, press the Find button and specify your selection. You get a list of all entries matching your selection. Place the cursor on the one you want, and press F2 or simply double-click the destination. All information for the given entry appears.
Creating Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
All available connection types are explained in Types of Destinations.
To create a new RFC destination, press the Create button. A new screen is displayed with empty fields for you to fill in.
If you want to create a new destination
As you create a remote destination, you can specify a particular application server or a group of servers for a balanced distribution of system load.
For details of the destination parameters, see Entering Destination Parameters.
Changing Existing Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
You can display all information for a given destination by double-clicking it or pressing F2 on it.
To change an existing destination, double-click it, or place the cursor on it and press the Change button.
For details of the destination parameters, see Entering Destination Parameters.
Testing Destinations
To test a destination, choose the appropriate function from the Test menu.
Connection (also available via the Test connection pushbutton)
Authorization (checks logon data)
Local network (provides a list of application servers)
You can use the CALL FUNCTION statement to call remote functions, just as you would call local function modules. However, you must include an additional DESTINATION clause to define where the function should run:
CALL FUNCTION RemoteFunction
DESTINATION Dest
EXPORTING
f1 =...
f2 =...
IMPORTING
f3 =...
TABLES
t1 =...
EXCEPTIONS......
The field Dest can be either a literal or a variable: its value is a logical destination (for example, "hw1071_53") known to the local SAP System. Logical destinations are defined in the RFCDES table (or the TRFCD table in R/2 Systems) via transaction sm59 or the following menu path: Tools ® Administration, Administration ® Network ® RFC destinations. You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® Customizing ® Enterprise IMG. In the Implementation Guide, you can then choose Cross-application components ® ALE ® Communication ® Define RFC destination.
The remote function call concept, for example, allows you to access a function module in an R/2 System from an ABAP program in an R/3 System. If you want to read a customer record from your R/2 Systems database, create a remotely callable function module in the R/2 environment which retrieves customer records. Call this function from your R/3 System using a remote function call and listing the destination for the target R/2 System:

Creating a Function module to send XML Byte String

Hi all,
I have to create a Function module to get XML byte string.The internal table is dynamic coloums based on how many data selected as a importparameter.from the internal; table data I have to create a XML byte string as a output.Pl help me to proceed further.
Thanks in Advance.
Ram

If i have your question right you need to convert an internal table of unknown type to an xml string then to a byte string.
data xmlString type string.
data xmlXString type xstring.
call transformation id
   source
      table = internalTableYouWantToExport
   result
      xml xmlString.
export xmlString to data buffer xmlXString.
xmlString has the xml of the table and xmlXString contains the byte representation of the string.

Using a function module i want to create another function module

Hi all,
My requirement is by using a function module i want to create another function module(if needs modify action should also be done if i need this is for the created function module) and the main thing is that the function module which we are used to create is should be RFC enabled.
Thanks,
Vichu.

Hi,
You can do one thing... you write the BDC code in the function module name you are creating... so that if you call the function module in a program and execute that program and if you give the function module to be created in the selection screen of the program... in this way there is chance of creating another function module.
Hope this would help you.
Good luck

Creating a function module in background

Hi
Is there any way by which if i want to create any function module in background .
like in any screen i have created a button and on pressing that button a blank fucntion module should be created in the function group that is already created .
waiting for your reply.

Hello, Ashish;
When you mention a "Function Module" where are you trying to create it? The report designer? A .NET form?
What version of Crystal Reports are you using?
What version of Visual Studio .NET?
What requirements are you trying to meet?

Creating BW Function module to extract R3 Function module data.

Could you tell me how to create a BW Function Module to Extract data from R/3 Function module?.
Also, the BW function module needs to pass a date/time filter to R/3 function module basis which the R/3 function module passes the date/time restricted data to BW function module.
Thanks,
Gautam

You will have to create a function module in R/3 and then call the same in BW using the RFC call function option.
Please do not raise separate threads for each question - you have asked the same question in another post of yours..

Is it possible to call Normal function Module from WD4A , Not RFCs

Is it possible to call Normal function Module(FM) from WebDynPro for ABAP , Not RFCs

There is no difference, unless you are specifically calling the RFC to connect to another system. If so, then you need to add the DESTINATION keyword to the function call and specify the destination name. This name must be defined in SM59. But, if you are not going to another system, you can call the RFC the same way you call the regular function module.

Hi,
You can use the function module RS_FUNCTION_DELETE to do that.
Make sure you are not deleting any standard FM's.
Example
      call function 'RS_FUNCTION_DELETE'
           exporting
                funcname          = 'ZFM_NAME" " Function modue name
                suppress_popups   = 'X' " TO suppress any pop-ups that come when you delete
           exceptions
                error_message     = 1
                cancelled         = 2
                function_released = 3
                others            = 4.

I need to create RFC function module which creates the IDOC

Hi-
Any idea how to create RFC function module which creates the outbound IDOC. If you have any sample code please forward to me.
Thanks,
Sony

My Problem is
Whenever they create Invoice using T-code's like FV65(Parked Document), automatically should create IDOC's...
I have used message type FIDCC1 but this message type is usefull only for Posting documents.
1. Whenever they create parked document, entries will be stored in BKPF(Parked Document-Filed-BKPF-BSTAT = 'V') and Bseg....
2. I have to read entries from those tables and should create IDOC...
3. I checked FM's(FI_IDOC_CREATE_FIDCC1, FI_IDOC_PREPARE) but are not useful...
4. Now I need to write one RFC function module and that FM should create the IDOC's....
Can anyone please help me out?
Thanks,
Sony

How to create a Function Module

Hi
Please tell me the procedure to create a function module.
Thanks in advance,
Priya

Hi Srinivas,
In order to create a function module firstly you need to assign it to a function group.
In order to create function group goto t-code se37.
Choose Goto->Function groups-> Create group .
Give the function group name.
Then come back to se37 type in the name of your FM and then press <b>CREATE</b> button.
