Why and how to use events in abap objects

Dear all,
Please explain me why and how to use events in abap objects with real time example
regards
pankaj giri

Hi Pankaj,
I will try to explain why to use events... How to use is a different topic.. which others have already answered...
This is same from your prev. post...
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.
Varun.

How to use wildcards in ABAP query where condition?

Hi,
Please tell me how to use wildcards in ABAP qurey where condition.
e.g. select * from mara where matnr = * (wildcard we need to use.
Thanks & Regards,
Gaurav T

Do you want to query asterix * ?
select * from mara where matnr = '*'. "then just put it in apstrophes
or you want certain part of string be used as * ?
select * from mara where matnr like '%*' "then use % sign before it
or maybe you want something like this
select * from mara where matnr like '%1' . "then it will look for all materials having '1' inside it

How to use RSAN_PROCESS_EXECUTE in abap program

Hi all,
Does someone know how to use RSAN_PROCESS_EXECUTE in a abap program to execute an analytical process created in the transaction RSANWB?
I create a variant 'ZPC_ALIM_DL' for RSAN_PROCESS_EXECUTE. I would like to execute this program with this variant in a background job, but it seems that the job executed but it does nothing.
See below a part of the code.
SUBMIT RSAN_PROCESS_EXECUTE
             WITH VARIANT = 'ZPC_ALIM_DL'
             USER SY-UNAME VIA JOB L_JOBNM1 NUMBER L_JOBCOUNT1
             AND RETURN.
Thanks in advance,
L.

Hi Ludovic,
          I am using RSAN_PROCESS_EXECUTE with a variant in process chain. simply include 'abap program' type in process chain mention RSAN_PROCESS_EXECUTE as the program name and mention the variant you created for your apd process and run. I have tested it in dev and it has worked for me. let me know if this helps!
Thanks

How to use cursor function for nested xml

Hi,
i have a query for XMLQuery like
select * from bills where bill_id=????
it results in something like
<bills>
<bill>
<city>london</city>
<amount>44</amount>
</bill>
<bill>
<city>london</city>
<amount>988</amount>
</bill>
<bill>
<city>new york</city> <amount>59</amount> </bill>
</bills>
but i want xml output to be sorted for city names adding one more level location like
<bills>
<location city="london">
<bill>
<amount>44</amount>
</bill>
<bill>
<amount>988</amount> </bill>
</location>
<location city="new york">
<bill>
<amount>59</amount> </bill>
</location>
</bills>
it should be possible to iterate through the same table to gather informaton with the help of cursor function, but never used CURSOR before.
any idea?

p_desig works as a comma delimited string without the NVL function, that's not the issue.
It IS the issue .. you need to provide a SAMPLE so we can see what you're doing ..
How are you "passing it in" ?
option A:
procedure ( in_var in VARCHAR2 )
AS
and nvl(sn.c_attribute1,'x@#$%') in nvl(in_var,'x@#$%')
option B:
and nvl(sn.c_attribute1,'x@#$%') in nvl(&1,'x@#$%')
.. or some other method?

how to use it in php program?

Hi,
I do not know what exactly is Your question about. I'll try to give an overview:
1. "CURSOR CUR_ORDER IS" is PL/SQL syntax, not PHP
2. result of oci_parse call is in fact a CURSOR, so I think You already know how to use it.
3. if Your question is on how to pass cursor between PL/SQL and PHP, I use:
a) PL/SQL procedure:
CREATE OR REPLACE
PROCEDURE TEST_P (PO_REF_CURSOR OUT SYS_REFCURSOR) AS
BEGIN
OPEN PO_REF_CURSOR FOR -- Opens ref cursor for query
SELECT OBJECT_NAME, OBJECT_TYPE FROM USER_OBJECTS WHERE ROWNUM <= 5;
END;
b) in PHP:
$conn = ocinlogon($database_user, $database_passwd, $database); // connect database
$outrefc = ocinewcursor($conn); //Declare cursor variable
$mycursor = ociparse ($conn, 'begin test_p(:curs); end;'); // prepare procedure call
ocibindbyname($mycursor, ':curs', $outrefc, -1, OCI_B_CURSOR); // bind procedure parameters
$ret = ociexecute($mycursor); // Execute function
$ret = ociexecute($outrefc); // Execute cursor
$nrows = ocifetchstatement($outrefc, $data); // fetch data from cursor
ocifreestatement($mycursor); // close procedure call
ocifreestatement($outrefc); // close cursor
ocilogoff($conn); // close database connection
var_dump($data); // show content fo $data variable
Now $data contains arrays of columns with arrays of rows from query.
Hope it helps You,

Pawel

If you mean writing cursor with parameters you could try this way.
CURSOR c1 (name VARCHAR2, salary NUMBER) IS SELECT ...
--- open the cursor:
OPEN c1(emp_name, 3000);

How to use cursor data in more than one location in form?

hi all.
is it possible to make cursor as global or public in the form so i can use its data in more than location for testing like in buttons triggers.
for example:
if i declare the following cursor in "WHEN-NEW-FORM-INSTANCE" trigger
CURSOR cur
IS
SELECT ID, NAME
FROM PERSON;how can i use this cursor in other triggers in other buttons in the form?
thanks

kareem wrote:
now i have the old data- from cursor and the new- from tableNo, you have not. When you open the cursor you get the state of the database at the current SCN.
If you
- open your cursor, fetch the data and close the cursor
- update some data
- open your cursor, fetch the data and close the cursor
you will get the updated data from your cursor the second time (unless your update isn't a uncommited autonomous transaction but I wouldn't go down that route).
You will have to save your data somewhere or you might take a look at flashback: http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/consist.htm#i20759

1) I'm hoping that this is a homework assignment. You would never, in the real world, store a password in clear text. And you would never, from a database design, have separate Password and ConfirmPassword columns.
2) The INTO clause can accept a list of variables. So
FETCH your_cursor_name INTO local_variable1, local_variable2;would be valid.
3) You would generally want to avoid having local variables that share the name of a column-- that leads to some pretty serious confusion related to scoping. One common convention is to prefix local variables with a "l_".
4) You would generally want local variables to inherit the type of the column rather than explicitly declaring the length of a string in your procedure. That way, if you change the table in the future, your code will continue to work.
5) And finally, a procedure that just calls DBMS_OUTPUT would cause all sorts of red flags in reality. It would make far more sense for this to be a function that returns a value than a procedure that tries to write to a buffer that the client application may or may not have created.

How to use FORMULA in ABAP for calculation

hi all,
i have to do some calculation in my report and because of this reason i want to use formula. Could any body tell me the best way to use of formula for calculation purpose in ABAP or any other way?
Thansk,
abapfk
Moderator Message: You don't need to open a thread to know the answer for this basic question. A simple search or using ABAP Help will help in getting the answer.
Edited by: kishan P on Oct 4, 2010 11:20 AM

There is another option to do the same thing.
What can be done is, create running total. You can create running total from field explorer by right clicking and then new. Create Running Total Field dialog box appears. In that, provide the following:
i)     Field to summarize - provide the field to maximize (i.e. id)
ii)     Type of summary u2013 Maximum
iii)     Evaluate u2013 On change of field (provide the name)
iv)     Reset u2013 Never
Keep this Running total field on the details section and suppress if you do not want to show it in the details section. Place this field wherever you want in the report.
Hope this helps you. Let me know your comments.

Hi
   Check below sample code.

DATA flag(1) TYPE c.
SELECTION-SCREEN:
    BEGIN OF LINE,
      PUSHBUTTON 2(10) but1 USER-COMMAND cli1,
      PUSHBUTTON 12(10) but2 USER-COMMAND cli2,
    END OF LINE,
    BEGIN OF LINE,

      PUSHBUTTON 12(10) but4 USER-COMMAND cli4,
    END OF LINE.
AT SELECTION-SCREEN.
CASE sscrfields-ucomm.
    WHEN 'CLI1'.
      flag = '1'.
    WHEN 'CLI2'.
      flag = '2'.
    WHEN 'CLI3'.
      flag = '3'.
    WHEN 'CLI4'.
      flag = '4'.
ENDCASE.
INITIALIZATION.
MOVE: 'Button1' to but1,
        'Button2' to but2,
        'Button3' to but3,
        'Button4' to but4.
START-OF-SELECTION.
CASE flag.
    WHEN '1'.
      WRITE / 'Button 1 was clicked'.
    WHEN '2'.
      WRITE / 'Button 2 was clicked'.
    WHEN '3'.
      WRITE / 'Button 3 was clicked'.
    WHEN '4'.
      WRITE / 'Button 4 was clicked'.
    WHEN OTHERS.
      WRITE / 'No Button was clicked'.
ENDCASE.
Note that WRITE statements will not work in AT SELECTION-SCREEN events, alternativey you can use some popup to display the same.
   You can also check demo program: DEMO_SEL_SCREEN_PUSHBUTTON
   Hope this clarifies you.
