Difference between function module and userexit and badi

Hello Gurus,
As a functional consultant i want to know what is function module and user exit and badi.
what is the difference between function module , user exit and badi?

Rama,
Function modules are ABAP routines that are administered in a central function library. They apply across applications and are available throughout the system. You must assign function modules to a function pool that is called a function group. A function group is nothing but a container for the function modules.
Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
User exit - A user exit is a three character code that instructs the system to access a program during system processing.
SXX: S is for standard exits that are delivered by SAP.   XX represents the 2-digit exit number.
UXX: U is for user exits that are defined by the user. XX represents the 2-digit exit number .
Difference between BADI and USER-EXIT.
    i) BADI's can be used any number of times, where as USER-EXITS can be used only one time.
       Ex:- if your assigning a USER-EXIT to a project in (CMOD), then you can not assign the same to other project.
    ii) BADI's are oops based.
Hope this helps you.

Difference between function module and a method?

Hi Experts
Can anybody pls tell me the technical and functional difference between function moduel and a method?
Thanks
Sudhansu

Hi,
Function modules are procedures that are defined in function groups (special ABAP programs with type F) and can be called from any ABAP program. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the R/3 System. They are stored in a central library. The R/3 System contains a wide range of predefined function modules that you can call from any ABAP program. Function modules also play an important role in database updates and in remote communications between R/3 Systems or between an R/3 System and a non-SAP system.
You can declare methods in the declaration part of a class or in an interface. To declare instance methods, use the following statement:
METHODS <meth> IMPORTING.. [VALUE(]<ii>[)] TYPE type [OPTIONAL]..
               EXPORTING.. [VALUE(]<ei>[)] TYPE type [OPTIONAL]..
               CHANGING.. [VALUE(]<ci>[)] TYPE type [OPTIONAL]..
               RETURNING VALUE(<r>)
               EXCEPTIONS.. <ei>..
When you declare a method, you also define its parameter interface using the additions IMPORTING, EXPORTING, CHANGING, and RETURNING. The additions define the input, output, and input/output parameters, and the return code. They also define the attributes of the interface parameters, namely whether a parameter is to be passed by reference or value (VALUE), its type (TYPE), and whether it is optional (OPTIONAL, DEFAULT).
Unlike in function modules, the default way of passing a parameter in a method is by reference.
As in function modules, you can use exception parameters (EXCEPTIONS) to allow the user to react to error situations when the method is executed.
As in function modules, you can use the RAISE <exception> and MESSAGE RAISING statements to handle error situations.

Difference Between Function Module And BAPI

Hi Friends,
What is the technical difference between BAPI and Function Module (Normal, RFC and update)?
When do we use BAPI and FM?
If BAPI is also RFC enabled then why do we have RFC function module?
Kindly clarify with examples.
Regards,
Pradeep Singh Dhadwal

Hi Pradeep,
BAPI vs FM
Difference between FM and BAPI
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module
ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access.
Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects.
You create business objects and those are then registered in your BOR (Business Object Repository)
which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA.
FM
Normal FM used internally inside SAP.
Hope this helps,
Manish

Difference between Function Module and Routine

Hi,
I am zero at ABAP Skill.
Can any one explain me what is the difference between Routine in BW and Function Module .
Thanks

Hi,
well basically it is almost the same. Both have a defined interface. You can pass variables to them and they can return variables. They can also change parameters... The main difference is, that a routine (form routine) can be used within the program where it is defined only and a function module can be used in all programs, form routines.

Difference between function module and subroutines

hey all...
can u pls explai me the exact difference between subroutines and function modules...
also, when is a sub routine used and also when is a function module used..???
regards..
vishal

Hi Vishal,
Basically they do the same thing and purpose is almost same but tecnically the are way apart:
Function modules must belong to a pool called a function group.
They possess a fixed interface for data exchange. This makes it easier for you to pass input and output parameters to and from the function module.
For example, you can assign default values to the input parameters. The interface also supports exception handling. This allows you to catch errors and pass them back to the calling program for handling.
They use their own memory area. The calling program and the function module cannot exchange data using a shared memory area - they must use the function module interface. This avoids unpleasant side effects such as accidentally overwriting data.
You call a function module by its name (which must be unique) in a CALL FUNCTION statement.
and also
Unlike subroutines, you do not define function modules in the source code of your program. Instead, you use the Structure link Function Builder.
Check this link too

Difference between Function module and a subroutine

hi
In the case of subroutine i can access the global workarea values.
I want to know whether in the case of function module
whether
i can follow the same procedure to access the workarea values
or
i have to pass this workarea values as an import or tables parameter to the function module and then use it
(in first case whether that workarea to make global whether i have to place it in function pool please check this but which is better one)
Thx in advance for any replies.

Yes
You would have to pass the values as import parameters to access the global variables of the program otherwise you will not be able to get the values of the global variable from inside the program.
Another solution would be to export to SAP memory but the entire concept of modularization of using the FM would be lost.

Difference between Function module in Update task

Hi folks,
What is the difference between
1. A function module calling in 'update task'( if attributes not set for update mode).
2.A function module's attributes set to update mode, but while calling not specified 'Update task'.
Please clarify this doubt.
Thanks in advance.
Bhavani

CALL FUNCTION func IN UPDATE TASK.
Additions:
1. ... EXPORTING p1 = f1 ... pn = fn
2. ... TABLES p1 = itab1 ... pn = itabn
Effect
Flags the function module func for execution in the update task. It is not executed at once, but the data passed with EXPORTING or TABLES is placed in a database table and a subsequent COMMIT WORK then causes the function module to be executed by the update task. Update function modules must be flagged as such in the Function Builder
The return value is not set.
Addition 1
... EXPORTING p1 = f1 ... pn = fn
Effect
Values of fields and field strings specified under EXPORTING are passed from the calling program to the function module. In the function module, the formal parameters are defined as import parameters. In the interface definition, default values must be assigned to all import parameters of the update function module.
Addition 2
... TABLES p1 = itab1 ... pn = itabn
Effect
TABLES passes references to internal tables. All table parameters of the function module must have values.
Note
With update function modules, both import parameters and exceptions are ignored when the call is made.

Difference between Function Module Vs Method in Class Module

1) Can you please tell the difference between the Function module used in abap program and the method of the class module used in abap programming.
2) does it necessary to do commit statement after calling the function module.
Thankyou for you time.
Bhaskar.

Hi,
1)
Check this difference..
The main difference between real object orientation and function groups is that although a program can work with the instances of several function groups at the same time, it cannot work with several instances of a single function group. Suppose a program wanted to use several independent counters, or process several orders at the same time. In this case, you would have to adapt the function group to include instance administration, for example, by using numbers to differentiate between the instances.
2) COMMIT WORK is required for BAPI..And not required when you normally call a function module..Unless required ..
Example
Update function modules requires COMMIT WORK to execute the function module.
Thanks,
Naren

Diff between Function Module and subroutine

sir,
explain the difference between Function Module and Subroutine.

Hi Sandeep,
Subroutines:
Subroutines are procedures that you can define in any ABAP program and also call from any program. Subroutines are normally called internally, that is, they contain sections of code or algorithms that are used frequently locally. If you want a function to be reusable throughout the system, use a function module.
Function Modules:
Function modules are procedures that are defined in function groups (special ABAP programs with type F) and can be called from any ABAP program. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the R/3 System. They are stored in a central library.
Unlike subroutines, you do not define function modules in the source code of your program. Instead, you use the Function Builder.

Difference in functional modules

Dear all,
What is the difference between functional modules FI_period_Determine and Period_day_Determine? Under which scenarios they are used?
Thanks and Regards,
vijay

hi
To check whether Posting date belongs to closed period we can use 2 FM's in sequence. Firstly call Function Module FI_PERIOD_DETERMINE .and Then call Function module FI_PERIOD_CHECK to check whether Period belongs to closed period or not
If you know year, month and fiscal year variant and you want to know the first date and end date of that period, you can apply function module "PERIOD_DAY_DETERMINE" in ABAP/4 to get them.
hope it helps
