Hi Morgan,
You can start going thorugh the concepts from help.sap.com. Have a look at the following link:
http://help.sap.com/erp2005_ehp_04/helpdata/EN/1b/337930a63011d2bd6b080009b4534c/frameset.htm
You will get the entire set of Example codes in the Transaction Code : ABAPDOCU.
You can also look for examples for Dialog Programing in SE38 using the DEMODYNPRO*.
Have a look at the Package : SLIS. This is a one point of all examples and demo of SAP Control Framework and ALV Functionality.
Hope this helps.
Thanks,

Link BOR Event with ABAP code (program or function)!

Hello experts,
I am trying to link program or function to bor event. Change of data in HR IT0002 trigger event CHANGE of PERSDATA Object. I need to execute some ABAP code (program or function) on CHANGE event, so I have to link event and ABAP code.
Question: is it possible and how?

Hi,
It is very much possible....
You can use the Workflow & use BO as PERSDATA & this workflow can be triggered on event change.
& You can write your code ...

Can we use Initilization event in module pool program?

Hi All,
Can we use Initialization event in module pool program? If not why?
Thanks In Advance!!!!!!!!!

The runtime environment creates the INITIALIZATION event and calls the corresponding event block (if it has been defined in the ABAP program).

INTERFACE AND EVENTS IN ABAP OO

Can some one explain me the real time need with example for use of interfaces and events in abap objects
(asking interface and events along doesnt mean that i am relating them).

Events :
Technically speaking :
" Events are notifications an object receives from, or transmits to, other objects or applications. Events allow objects to perform actions whenever a specific occurrence takes place. Microsoft Windows is an event-driven operating system, events can come from other objects, applications, or user input such as mouse clicks or key presses. "
Lets say you have an ALV - An editable one ...
Lats say - Once you press some button you want some kind of validation to be done.
How to do this ?
Raise an Event - Which is handled by a method and write the validation code.
Now you might argue, that I can do it in this way : Capture the function code - and call the validate method.
Yes, in this case it can be done.. But lets say .. you change a field in the ALV and you want the validation to be done as soon as he is done with typing.
Where is the function code here ? No function code... But there is an event here - The data changed event.
So you can raise a data changed event that can be handled and will do the validation.
It is not user friendly that you ask the user to press a button (to get the function code) for validation each time he enters a data.
The events can be raised by a system, or by a program also. So in this case the data changed event is raised by a system that you can handle.
Also, Lets say on a particular action you want some code to trigger. (You can take the same example of validation code). In this case the code to trigger is in a separate class. The object of which is not available here at this moment. (This case happens very frequently).
Advantage with events : Event handlers can be in a separate class also.
e.g : In the middle of some business logic .. you encounter a error. You want to send this information to the UI (to user - in form of a pop up) and then continue with some processing.
In many cases - A direct method call to trigger the pop up is not done. Because (in ideal cases) the engine must not interact with UI directly - Because the UI could be some other application - like a windows UI but the error comes from some SAP program.
So - A event is raised from the engine that is handled in the UI and a pop up is triggered.
Here -- I would have different classes (lets say for different Operating Systems). And all these classes must register to the event ERROR raised in application.
And these different classes for different Operation systems will have different code to raise a pop-up.
Now you can imagine : If you coded a pop-up for Windows (in your application logic) .. it will not work for Mac or Linux. But of you raise a event.. that is handled separately by a different UI classes for Win, Linux or Mac they will catch this event and process accordingly.
May be I complicated this explanation .... but I couldn't think of a simpler and concrete example.
Cheers.

Events in ABAP runtime.

Can Any one explain me the events in ABAP runtime with proper example please.

Hi Srnivas,
Here are the events in order
Classical Report Events:
Initialization
At selection-screen
at selection-screen output
start-of-selection
end-of-selection
top-of-page
end-of-page
Interactive Report Events:
Above events and also,
at line-selection,
at user-command,
at pfn
The following events occur at runtime of a typical report program which uses logical databases:
Event keyword Event
INITIALIZATION Point before the selection screen
is displayed
When you start a program in which a selection screen is defined (either in the program itself or in the linked logical database program), the system normally processes this selection screen first. If you want to execute a processing block before the selection screen is processed, you can assign it to the event keyword INITIALIZATION.
AT SELECTION-SCREEN Point after processing user
input on the selection screen while the selection screen is still active
The event keyword AT SELECTION-SCREEN provides you with several possibilities to carry out processing blocks while the system is processing the selection screen.
START-OF-SELECTION Point after processing the selection screen
The event START-OF-SELECTION gives you the possibility of creating a processing block after processing the selection screen and before accessing database tables using a logical database. You can use this processing block, for example, to set the values of internal fields or to write informational statements onto the output screen.
At the START-OF-SELECTION event, also all statements are processed that are not attached to an event keyword except those that are written behind a FORM-ENDFORM block
GET <table> Point at which the logical database
offers a line of the database table <table>.
The most important event for report programs with an attached logical database is the moment at which the logical database program has read a line from a database table (see Accessing Data Using Logical Databases ). To start a processing block at this event, use the GET statement as follows:
Syntax
GET <table> FIELDS <list>.
After this statement, you can work with the current line of the database table <table>. The data is provided in the table work area <table>.
GET <table> LATE Point after processing all tables which
are hierarchically subordinate to the database table <table> in the structure of the logical database.
To start a processing block at the moment after the system has processed all database tables of a logical database that are hierarchically inferior to a specific database table, use the event keyword GET as follows:
Syntax
GET <table> LATE FIELDS <list>.
In analogy to report programs that use only SELECT statements (see table in Comparison of Access Methods ), the processing block of a GET <table> LATE statement would appear directly before the ENDSELECT statement in the SELECT loop for the database table <table>.
END-OF-SELECTION Point after processing all lines offered
by the logical database.
To define a processing block after the system has read and processed all database tables of a logical database, use the keyword END-OF-SELECTION.
The following events occur during the processing of the output list of a report program:
Event keyword Event
TOP-OF-PAGE Point during list processing when
a new page is started
END-OF-PAGE Point during list processing when a page
is ended
The following events occur during the display of the output list of a report program:
Event keyword Event
AT LINE-SELECTION Point at which the user selects a line
AT USER-COMMAND Point at which the user presses a function key or enters a command in the command field.
AT PF<nn> Point at which the user presses the
function key with the function code PF<n>
With the selection screen, ABAP/4 offers an interactive element also for report programs. You can define a selection screen without having to bother about all the details required in dialog programming.
The selection screen is always processed directly after a report program is started. The user can enter field values and selection criteria on this screen.
Reward points if useful.
Cheers,
Swamy Kunche

ABAP HR PROGRAMMING MATERIAL

Hi All,
I want <b>ABAP HR Programming Material</b>.......
Plz. suggest me, from where i can select this material, it's URGENT for me.....
Thanks & Regards,
<b>Anil Kumar</b>

Hi
HR:
HR deals with the INFOTYPES which are similar to Tables in General ABAP.
There are different ways of fetching data from these infotypes.
There are different areas in HR LIKE Personal Admn, Orgn Management, Benefits, Time amangement, Event Management, Payroll etc
Infotypes for these areas are different from one another area.
storing of records data in each type of area is different
LDBS like PNP are used in HR programing.
Instead of Select.. we use some ROUTINES and PROVIDE..ENDPROVIDE.. etc
and in the case of Pay roll we use Clusters and we Import and Export them for data fetching.
On the whole Normal ABAP is different from HR abap.
For Personal Admn the Infotypes start with PA0000 to PA1999
Time Related Infotypes start with PA2000 to PA2999.
Orgn related Infotypes start with HRP1000 to HRP1999.
All custom developed infotypes stsrat with PA9000 onwards.
In payroll processing we use Clusters like PCL1,2,3 and 4.
Instead of Select query we use PROVIDE and ENDPROVIDE..
You have to assign a Logical Database in the attributes PNP.
Go through the SAp doc for HR programming and start doing.

What is the need of END-OF-SELECTION event in ABAP reporting

Hi,
Can anyone explain the need of the END-OF-SELECTION event in ABAP Reports?
This event is used to terminate the previous event. Is that right? or is there any specific use of it?
and when exactly we use this event while writing a report? I mean what purpose?
Thanks,
Paddu.

Hi,
END-OF-SELECTION makes more sense when you are using logical database in your program.
See these links.
http://help.sap.com/saphelp_46c/helpdata/en/34/8e74266df74873e10000009b38f9b8/frameset.htm
http://help.sap.com/saphelp_46c/helpdata/en/9f/db9aca35c111d1829f0000e829fbfe/frameset.htm
After all the data has been selected END-OF-SELECTION event writes the data to the screen
The END-OF-SELECTION event is triggered in executable programs once the logical database has finished reading all data and before the list processor is started.
Try to go thro this link.
http://help.sap.com/saphelp_46c/helpdata/en/9f/db9a1435c111d1829f0000e829fbfe/frameset.htm
Mostly end-of-selection is used in logical data base. It is not mandatory.
Ex:
If you use a logical database in your report then this event is mandatory because when all the data selection from the database is finished this events get triggers.
For example if you are populating a internal table using a logical data base event 'GET' then you need this event because if you don't use this you get display again and again for each selection.
START-OF-SELECTION.
GET PERNR.
itab-pernr = pernr-pernr.
append itab.
*this get triggers after all selection from database.
END-OF-SELECTION.
loop at itab.
write:/ itab-pernr.
endloop.

Padmam.

Event for ABAP Objects

Dear All,
Would you mind tell me the concept of the event in the ABAP objects.
Regards,
Luke

hI
Triggering and Handling Events
In ABAP Objects, triggering and handling an event means that certain methods act as triggers and trigger events, to which other methods - the handlers - react. This means that the handler methods are executed when the event occurs.
This section contains explains how to work with events in ABAP Objects. For precise details of the relevant ABAP statements, refer to the corresponding keyword documentation in the ABAP Editor.
Triggering Events
To trigger an event, a class must
·        Declare the event in its declaration part
·        Trigger the event in one of its methods
Declaring Events
You declare events in the declaration part of a class or in an interface. To declare instance events, use the following statement:
EVENTS ) TYPE type ..
To declare static events, use the following statement:
CLASS-EVENTS ... ...
It links a list of handler methods with corresponding trigger methods. There are four different types of event.
It can be
·        An instance event declared in a class
·        An instance event declared in an interface
·        A static event declared in a class
·        A static event declared in an interface
The syntax and effect of the SET HANDLER depends on which of the four cases listed above applies.
For an instance event, you must use the FOR addition to specify the instance for which you want to register the handler. You can either specify a single instance as the trigger, using a reference variable ...
The registration applies automatically to the whole class, or to all of the classes that implement the interface containing the static event. In the case of interfaces, the registration also applies to classes that are not loaded until after the handler has been registered.
Timing of Event Handling
After the RAISE EVENT statement, all registered handler methods are executed before the next statement is processed (synchronous event handling). If a handler method itself triggers events, its handler methods are executed before the original handler method continues. To avoid the possibility of endless recursion, events may currently only be nested 64 deep.
Handler methods are executed in the order in which they were registered. Since event handlers are registered dynamically, you should not assume that they will be processed in a particular order. Instead, you should program as though all event handlers will be executed simultaneously.

Abap Interface program

Can any one tell me a short description about Abap interface program also the difference between inbound and outbound interfaces ??

Hi
Interfaces
Interfaces only describe the external point of contact of a class (protocols), they do not contain any implementation.
Interfaces are usually defined by a user. The user describes in the interface which services (technical and semantic) it needs in order to carry out a task.
The user never actually knows the providers of these services, but communicates with them through the interface.
In this way the user is protected from actual implementations and can work in the same way with different classes/objects, as long as they provide the services required. This is known as polymorphism with interfaces.
Interfaces
In ABAP interfaces are implemented in addition to, and independently of classes. An interface only has a declaration part,
and do not have visibility sections. Components (Attributes, methods, constants, types) can be defined the same way as in classes.
· Interfaces are listed in the definition part lof the class, and must always be in the PUBLIC SECTION.
· Operations defined in the interface atre impemented as methods of the class. All methods of the interface
must be present in the implementation part of the class.
· Attributes, events, constants and types defined in the interface are automatically available to the class
carrying out the implementation.
· Interface components are addressed in the class by display.

Re : select-options in abap-objects program

Dear friends,
                  I want to give select-options in abap-objects program. How to give that.
                             Thanking You
with regards,
Mani

In the transaction SE24, enter your class name, click modify.
in the tab named "Types" you have to declare two types. By example, if you want to receive one select-options that in your program that uses this class is declared like:
" P_SAKNR FOR SKAT-SAKNR".
you've got to declare two types in the class:
a- TYPES: begin of E_S_SAKNR,
                      sign(1),
                      option(2),
                      low(10),
                      high(10),
                  end of E_S_SAKNR.
b - TYPES E_T_SAKNR type standard table of E_S_SAKNR.
so, in the class method that you want to receive P_SAKNR as importing parameter. You got to do this:
method TEST importing ET_SAKNR type E_T_SAKNR.
now, in the implementation of this method you should be able to use ET_SAKNR as the same way as you usually use a parameter or a select-option. You could use it in a select with the operator IN by example..
