Difference between custom controller and component controller

Hi All,
I am a beginner in CRM SAP .
Please can anyone tell me whats the difference between custom controller and component controller with some scenario.
I am totally baffled.
Thanks in advance.
Regards
Shilpi

Hi Shilpi,
The main difference between custom and component controller is the role which they play during data transfer.
a) Custom controller is used for data transfer across two views within a component. For that you need to bind view context nodes to custom controller either through wizard or manually by adding the code in CTXT class create_contextnode method:
initial setting for depandant model node
    coll_wrapper =
      BTADMINH->get_collection_wrapper( ).
    TRY.
        entity ?= coll_wrapper->get_current( ).
      CATCH cx_sy_move_cast_error.
    ENDTRY.
    IF entity IS BOUND.
      BTOpportH->on_new_focus(
                   focus_bo = entity ).
    ENDIF.
b)Component controller is used for data transfer across two views in two different components. For this, we need to define the component usage first and then bind the context nodes in the method-WD_USAGE_INITIALIZE of the Component Controller impl class.
    WHEN 'ComponentUsageName'.
      iv_usage->bind_context_node(
                  iv_controller_type = cl_bsp_wd_controller=>co_type_custom
                  iv_target_node_name = 'ContextNodeName' "#EC NOTEXT
                  iv_node_2_bind      = 'ContextNodeName' ). "#EC NOTEXT
Hope this clears some of your doubts!
Thanks and Regards,
Rohit
P.S-This is valid for CRM 2007.Raghu is also right because Interaction Center is made up of different different components combined together.You have put your question in wrong forum.

Difference between customizing request and workbench request?

Hi ,
What is the difference between customizing request and workbench request?
please reply.........

HI,
<b>Workbench Requests</b>
When you change a Repository object of the ABAP Workbench, a query window appears in which you need to specify a Workbench request. You can only save the changes if you have assigned the object to a change request.
Workbench requests and the tasks assigned to them are normally used to record changes to Repository objects and Customizing for all clients. However, you can also include client-specific Customizing.
Whether the changes to Repository objects are transported depends on whether a transport route is defined from the current SAP System for the package of these objects. From the system settings, the system automatically determines whether the change requests are transportable and to which target system they should be transported.
<b>Customizing requests</b>
Customizing requests record client-specific Customizing settings made in a single client (the source client of the request).
Automatic recording of configuration activities in the Customizing work for a client can be activated or deactivated for each client with Client Control. If automatic recording is active, a query window appears when you change Customizing settings, asking you to specify a Customizing request.
Whether Customizing requests are transported or not, does not depend on the objects entered, as is the case with Workbench change requests. The Customizing requests in an SAP System (or in a client if you use Extended Transport Control) are either all transportable or all local, depending on the system setting. The system uses the standard transport layer to determine automatically whether the change requests are transportable and to which target system they should be transported. However, you can change this manually.

Difference between customer exit and user exit?

hi experts
difference between customer exit and user exit?

These r the main differences between user exits and customer exits
1) user exits r subroutines where as customer exits r function modules
2) user exits r not upgraded where as customer exits r will upgrade
3) customer exits r used for creating and additional fields or menu items to stadard tcode where as user exits r used for enabling or disabling the fields on the standrd screen or concatenating the key fields,it is not used adding an additional componenats to stadard tcode
4) customer exits r reusable where as user exits r not reusable.
Also:
1. Customer exits: Implemented as Function Modules within z includes. Anybody can change it and no access key is required.
2. User Exit: Implemented as subroutines within includes (any include except y or z includes). You need access for the specific include and then you can any subroutine (user exit) within that Include.
BADIs are the enhanced version of user exits where the same logic is implemented via classes and object (OOP)
Enchancement point is the latest once introduces with ECC6.0 . Not very sure about that but you can change it without any access key.
Please go through the following link which will help you understand the exits in a much better way:

1. Previously there were only user-exits.
2. Then came the concept of customer-exits.
3. user exits were nothing but subroutines
FORM/PERFORM
called from standard programs.
4. The FORM defintion was placed inside
an empty include file.
5. So It was called EVERYTIME.
and we need to MODIFY/REPAIR the
standard include .
6. Then it came with concept of customer-exit
7. It consists of calling a FUNCTION MODULE,
which is called only if
the user-exit is ACTIVATED (other wise not called)
In this case, the code in put inside
a pre-defined Z include.
8. Functionality of both is same, howerver
we can note the following important differences
a) Customer exit is called only if activated.
(hence, it does not waste resources)
b) in customer exit, REPAIR does not happen
to the standard include.
Exits are basically the hooks whcih SAP has provided to add your own code.
User Exits: These are provided only SD module .
They are Empty subroutines with naming like USEREXIT_.
We need to have Access key to implement them.
Customer Exits: These are enhancement techniques.
There are defined in SMOD and implemented in CMOD.
Types of Customer exits: Function exit, Screen Exit, Menu exit.
User Exit and Customer Exit are same ,but SAP Exit and Customer exit are different...
Customer Exit,
Enables you to determine values for variables by means of Functional Module exit.The function module used is EXIT_SAPLRRSO_001.
Create a project in CMOD by selecting the SAP Enhancement RSR00001 and assign this to the enhanced proj and activate it.
Customer Exit
SAP creates customer exits for specific programs, screens, and menus within standard applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.
If you want to enhance the functionality of your SAP System, you should take advantage of the exits available in standard applications. There are two main reasons why you should use exits rather than modifying SAP software yourself. Add-ons attached to exits have the advantage that:
They do not affect standard SAP source code
When you add new functionality to your SAP System using SAPs exits, you do not alter the source code of standard SAP programs in any way. The code and screens you create are encapsulated as separate objects. These customer objects are linked to standard applications, but exist separately from SAPs standard software package.
They do not affect software updates
When you add new functionality to your SAP System using SAPs exits, your objects (called customer objects) must adhere to strict naming conventions. When it comes time to upgrade a to a new software release, customer objects names ensure that they will not be affected by any changes or new additions to the standard software package.
Customer exits are not available for all programs and screens found in the SAP System. You can only use customer exits if they already exist in the SAP System. You find find more information about locating applications with pre-defined exits in Locating Applications that have Exits

SAP EXIT:this processing type contained in variables that are delivered with SAP BW business content.
http://help.sap.com/saphelp_nw04/helpdata/en/1d/ca10d858c2e949ba4a152c44f8128a/frameset.htm
User Exits: allow you to add additional functions to the SAP standard.
Programs with user exits contain subroutine calls at certain points in their syntax that are identified by the prefix USEREXIT. The actual user exits are located in an include that has been assigned to a module pool. This is where customers can include any changes (enhancements) that they want to make to the system. These includes are always processed during program flow.
Advantage: In principle, customers can modify anything they want that is found in the include (tables, structures, and so forth).
Disadvantage: SAP cannot check the individual enhancements themselves which often leads to errors

What is the difference between customer exits and user exits?

hello friends,
what is the difference between customer exits and user exits?

Hi
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
Customer exit - The R/3 enhancement concept allows you to add your own functionality to SAPs standard business applications without having to modify the original applications. SAP creates customer exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.     *-- Mani
The following document is about exits in SAP :-
The R/3 enhancement concept allows you to add your own functionality to SAPs standard business applications without having to modify the original applications.
SAP creates user exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.
Types of Exits
There are several different types of user exits. Each of these exits acts as hooks where you can attach or "hang" your own add-ons.
Menu Exits
Menu exits add items to the pulldown menus in standard SAP applications. You can use these menu items to call up your own screens or to trigger entire add-on applications.
SAP creates menu exits by defining special menu items in the Menu Painter. These special entries have function codes that begin with "+" (a plus sign). You specify the menu items text when activating the item in an add-on project.
Screen Exits
Screen exits add fields to screens in R/3 applications. SAP creates screen exits by placing special subscreen areas on a standard R/3 screen and calling a customer subscreen from the standard screens flow logic.
Function Module Exits
Function module exits add functions to R/3 applications. Function module exits play a role in both menu and screen exits.
When you add a new menu item to a standard pull down menu, you use a function module exit to define the actions that should take place once your menu is activated.
Function module exits also control the data flow between standard programs and screen exit fields. SAP application developers create function module exits by writing calls to customer functions into the source code of standard R/3 programs.
These calls have the following syntax:
CALL CUSTOMER-FUNCTION 001.
Field Exits
Field exits allow you to create your own programming logic for any data element in the Dictionary. You can use this logic to carry out checks, conversions, or business-related processing for any screen field. Example: The data element BBBNR identifies a companys international location number. You might want to set up your R/3 System so that all international location numbers are larger than 100.
The field exit concept lets you create a special function module that contains this logic.
You assign the special function module to the data element BBBNR. You then assign the module to any programs and screens in which users can add new international location numbers. When you activate your field exit, the system automatically triggers your special routine whenever a user enters a company location number.
In 4.6c, you can use "RSMODPRF" program to create field exits.
An example of a user exits :-
MODULE user_exit_0001 INPUT
    CASE okcode.
        WHEN 'BACK OR EXIT'.
            CASE sy-dynnr.
                    WHEN '100'.
                         SET SCREEN 0.
                         LEAVE SCREEN.
                    WHEN '200'.
                         SET SCREEN 100.
                         LEAVE SCREEN.
             ENDCASE.
      ENDCASE.

Difference between customer exits and user exits

difference between customer exits and user exits

Hi,
USER EXITS->
1. Introduction:
User exits (Function module exits) are exits developed by SAP.
The exit is implementerd as a call to a functionmodule.
The code for the function module is writeen by the developer.
You are not writing the code directly in the function module,
but in the include that is implemented in the function module.
The naming standard of function modules for functionmodule exits is:
EXIT_<program name><3 digit suffix>
The call to a functionmodule exit is implemented as:
CALL CUSTOMER.-FUNCTION <3 digit suffix>
http://www.sap-img.com/abap/a-short-tutorial-on-user-exits.htm
CUSTOMER EXITS-> t-code CMOD.
As of Release 4.6A SAP provides a new enhancement technique, the Business Add-Ins.
Among others, this enhancement technique has the advantage of
being based on a multi-level system landscape (SAP, country versions, IS solutions, partner,
customer, and so on)
instead of a two-level landscape (SAP, customer) as with the customer exits.
You can create definitions and implementations of business add-ins at any level of the system landscape.
To unify enhancements of the SAP Standard you can migrate customer exits to business add-ins.
http://help.sap.com/saphelp_nw04/helpdata/en/c8/1975cc43b111d1896f0000e8322d00/content.htm
In order to find out the user exits for any tcode,
1. get the developement class of the tcode from SE93.
2. Now goto transaction SMOD and press F4,
3. give in the Deve class in the dev class and Press ENTER
this will show u the exits for any tcode.
or execute this report
http://www.erpgenie.com/sap/abap/code/abap26.htm
which gives the list of exits for a tcode

Difference between custom controller and interface component

Hi,
Can anybody tell me what are the differences between component controller and custome controller , component interface.
Thanks in advance.
Regards
sireesha.

hi,
When any component is created web dynpro framework automatically generates the controller(controller is nothing but entity which controls the working of views and acts as a binding layer between model and view), this controller is called Component controller.
We can have as many controller as we want, but they should be used sparingly, Controller should encapsulate the functionality which is common to whole component , like if your application fetches master data and appliaction data so better you should have 2 controller , 1 for master and 2 for application so as to have modularisation in your application.
Component Interface is the entity which is used when you want to use the functionality defined in some other component i.e. if your main component is acting as a parent comopnent then the child component usage should be defined via this interface controller under Component Interface, so that main compo will access it via childs Interface Controller.
Other node under this , Interface view , gets generated for every creation of window , Interface view is entry point into our application for web Dynpro framework
jsut check out following links,

Difference between Customer Include and Append

Hi all,
We are using a special customer namespace /XXX/. Regarding to this I can not use the Customer Includes (CI_Include) in the SAP tables anymore to add own fields.
To create my own fields anyway I create a append in the /XXX/ namespace and add my /XXX/fields to this Append.
It is working, but I want to know if there are situations where the use of an append instead of an include can cause errors?
What is the difference between include and append?
Thanks in advance for your help,
Fabian

Hi
NO, because they are the same thing, you use both includes to enhance a standard structure.
But the Append Include is only used in the structure where it's defined, CI_INCLUDE is used by enhancement so perhaps it can be used in many structures.
So you have to use CI_INCLUDE only if you need to you its enhancement.
If the name of include begin of CI_, you won't have any error if that include doesn't exist.
You can try to build a Z-TABLE and insert the include CI_ZMYINCLUDE after try to check your table: any errors'll occur.
The same this is for the include with the name begining with ZX...

Difference between interface view and interface controller

Hi,
What is the difference between interface controller and interface view?
When we will use interface controller and when we will use interface view?
How do we create an interface view?
How do we attach this interface view to a view in another component
Regards
MQ

Hi
Interface View Controllers
A) Implement event handlers which are called when ..
-starting (start-up plugs) Web Dypro applications
-a component is reached via navigation (inbound plugs)
B) Allow fireing outbound plugs (navigation)
C) Allow firing exit plug
D) Have no own context, public methods or events
Interface Controller of a Component
The interface controller of a Web Dynpro component contains all context nodes, events and methods of the component controller to which you assigned the Interface addition in the Controller Editor. These parts can be displayed in the interface controller view, although you cannot edit them here.
Interface Controller of a Component Interface
A Web Dynpro component interface can be created independently and defined so that it can be implemented later in any components (see working with Web Dynpro Component Interfaces in the Programming Manual of this documentation). That is why in this case you can define the context nodes, methods and events you require in the interface controller view. The relevant implementation then takes place in the component controller of the implementing component.
Check this links and work on it.

Difference between workbench request and customizing request in transport

Hi Experts,
I am new to SAP BI7 work. i am having basic doubt in Transort request creations
ususally we create the requests to transport the objects from Development system to further systems.
can anyone please clarify me, what is the main defference between the Workbench request and Customizing request.
Thanks and Regards
Mrudula

Hi ,
The Transport Organiser maintains Change Requests.These requests record the changes made to the repository and customizing objects.Based on that objects changed they are
1)WorkBench Request & 2) Customizing Request.
Workbench Requests are those that involve changes to cross-client Customising and Repository Objects. The objects are independent of the client.Hence the requests are used for transferring and transporting changed Repository objects and changed system settings from cross-client tables.
Customizing Requests involve changes recorded to client-specific Customizing objects .These client specific requests are used for copying and transporting changed system settings from client-specific tables.

Difference between Business Partner and Customer in ISU?

Is there any difference between business partner and customer in ISU?
if yes then wht?

Hi,
Yes Business Partner is a broad term used in ISU for various roles. A business Partner can be a Customer for company, an employee or even a vendor.
It depends on what role business partner has been given. Initially by default all Business Partners are assigned a default role "Business Partner (Gen.)". Later it can be changed to any role like Employee, Vendor, etc.
Business Partner with role "Contract Partner" is normally the end Customer which I believe you are referring to.

Difference between Business Partner and Customer Master repository

What is the difference between Business Partner and Customer Master repository ?
Is the Business Partner repository to be used in case CRM is also in landscape ? or Customer master repository is good enough ?
Sandesh

Hi,
If the landscape has both CRM and SAP ECC a business partner repository model should be good.
If it has ECC alone.a Customer Repository is needed.
But when there are many legacy systems which also contains master data fields, the standard business repository provided by SAP wont provide a good solution as it wont cover the legacy master fields..In this case its better to go for a customized repository and you can use the standard repository as a reference.

A quick search in the forum would have taken you to this answer
Workbench Requests

Workbench requests and the tasks assigned to them are normally used to record changes to Repository objects and Customizing for all clients. However, you can also include client-specific Customizing.

Difference between Customer Generated Extractors and Generic Extractors

Hi all,
Can anyone please tell me the difference between Customer Generated Extractors and Generic Extractors. I know that for all modules Generic extraction is possible by creating a datasource(RSO2) on top of a table, View or SAP Query in SE11. What are customer generated extractors like LIS, CO/PA and FI/SL.
What kind of extraction is used for FI/AR and FI/AP. To my understanding we have BW Content Extractors. Can anyone explain the extraction method and delta extraction for AR and AP.
Thanks,
Sabrina.

Hi,
Customer generated extractors are running on top of statistics data collection process in R/3. They extract data from statistical tables already available in R/3 and also use the mechanism already provided in R/3 to capture the delta.
For example, PO data goes to statistical table S012 (it is an LIS table) and you can build a generated extractor on top of it. The difference between such extractor and a generic one is the fact that these extractors (eg LIS) use the same mechanism of capturing delta that the statistics table was doing (for example data that goes into S012 is also captured by these generated extractors). Some system tables and structures are generated automatically to support this functionality, you do not have to develop anything for this.
Generic extractors on the other hand simply let you pull data from table/view/query etc. You have to develop code/functionality to support delta capturing for such extractors. If you built a generic extractor on top of S012 (it is a statistical table - LIS), you can pull its data to BW, but you do not have the delta capturing functionality in such case, you will have to code it yourself.
As a thumb rule, you go with the standard/generated extractors, and use generic extractors only if it is necessary to be so.
FI/AR and FI/AP extractors are part of business content (I think) and support delta functionality. To get detailed info on these, you can also look at help documentation -
