Exit from loop by user

Hi every body
i have a procedure that execute a loop.What i want that to allow user to exit from loop before it finished(by using keyboard), i do that by pressing ctrl+alt+del which end the program it self.

One could try putting the call to the procedure in a loop on the front end. Then check within the loop (in the front end ) whether the user has pressed a pre-defined button. If pressed, one could disconnect the connection or take some similar action that would stop processing the call to the stored procedure.
May be something like this is workable ... ?

EXITING FROM LOOP

if in a loop iam checkin a condition n if the condition satisfies then which is the best way to exit the loop.

Hi Sushant,
Use EXIT in the LOOP after the condition .If u use STOP it will exit from the Program.
Try this example creating a Program by uncommending EXIT and STOP.
DATA: t_mara TYPE STANDARD TABLE OF mara.
DATA: w_mara TYPE mara,
          sum     TYPE i.
SELECT matnr mtart FROM mara INTO CORRESPONDING FIELDS OF TABLE t_mara
WHERE mtart EQ 'KMAT' OR mtart EQ 'FERT' OR mtart EQ 'LGUT'.
sum = 0.
IF sy-subrc EQ 0.
SORT t_mara BY mtart.
LOOP AT t_mara INTO w_mara.
    IF w_mara-mtart EQ 'LGUT'.
      sum = sum + 1.

How to exit from a loop on 2 different conditions

Hello Experts
I’m trying to write a procedure in which I’m taking PROVINCE as an input parameter. All the provinces are stores in a table. I’m using a cursor and rowtype variable to check the province. After I finds province I displays province and its code. Everything works fine expect when I don’t find the province. I’m not sure how to exit from loop if I don’t find the province. I already uses exit when condition. I was expecting else condition should work and should exit from the loop but it doesn’t. Can please somebody show me how to exit if I don’t find province in the table through cursor.
Here is my code
set serveroutput on
variable G_TAX varchar2(10)
CREATE OR REPLACE PROCEDURE p_create(i_state VARCHAR2)is
CURSOR cur_bb_tax is
select * from bb_tax;
bb_tax_details bb_tax%rowtype;
begin
if not cur_bb_tax%isopen then
open cur_bb_tax;
end if;
loop
fetch cur_bb_tax into bb_tax_details;
if (bb_tax_details.state = i_state) then
dbms_output.put_line(bb_tax_details.state || bb_tax_details.idstate);
end if;
exit when bb_tax_details.state = i_state;
end loop;
close cur_bb_tax;
exception
when others then
dbms_output.put_line(SQLERRM);
end;
Thanks in advance

Hello,
Why don't you use dbms_output.Put_line and print output to find why logic is not able to execute? Maybe upper case/lower case/whitespace. *Also put your code between \ to preserve formatting*.

How to exit from while loop

Hi
I want to exit from loop if error is encountered.
THanks

Hi Sonu,
This is not a question related to the SDK. This is more of a coding question you should probably try something like StackOverflow or MSDN forums for that next time.
Regarding your question it depends on the language you are using. If you are using c# you can use the keyword "break;" inside an if that checks for the error. In VB you can use "Exit For" or "Exit While".
Best regards,

Stop Video Clip From Looping

After creating an iDVD movie containing multiple video clips and slideshows, one of the video clips Loops (but only once) before proceeding to the following slide show. I don't want it to loop but don't know how to stop it. Because it only loops once then proceeds, I have a strange feeling that this is a strange quirk rather than an errant iDVD setting. Also, none of the other videos loop.

Setting movies and slideshows to loop
You can set slideshows, autoplay movies (which start to play immediately when a DVD is inserted into a player, before the DVD menu appears), and movies to repeat continuously, or “loop.” This means they begin replaying immediately after they end. If they include audio, the audio also loops.
Looping an autoplay movie is especially useful for creating self-playing presentations, such as those used in tradeshow kiosks. For more information, see Related Topics below.
In map view you can see at a glance which slideshows and movies are set to loop. A circular arrow symbol appears in the bottom-right corner of the icon.
Here are ways to turn looping on or off:
◼
Double-click a slideshow button on the DVD menu to open the slideshow editor. Click the Settings button and select the “Loop slideshow” checkbox.
◼
Select a slideshow icon in map view, and then press Command-I to open the Slideshow Info window. Select the “Loop Slideshow” checkbox, and then close the window.
◼
Click a movie or slideshow button on the DVD menu, or a movie, slideshow, or autoplay movie icon in map view, to select it, and then choose Advanced > Loop Movie or Loop Slideshow.
When looping is turned on, a checkmark appears next to the command in the menu. To turn off looping, select it again to remove the checkmark.
◼
To turn looping off for a background movie on a menu, open the Menu Info window. With your pointer over the menu (but with no buttons or text items selected), press Command-I. Move the Loop Duration slider to zero.
When you’re viewing the burned DVD, you can press the Menu button on the DVD remote control to exit from looping.

Call an applications 'user exit' from a PL/SQL procedure

My question is a technical PL/SQL question related to Oracle Applications. I need to call a standard applications 'user exit' from a stored PL/SQL procedure. Can anyone tell me if this is possible and how to do it?

PO Creation from Sales Order User Exit

Hi,
I have a business requirement where I need to create a Stock Transport Order (STO) for a particular kind of sales order. I outlined different options for achieving this functionality.
1. Trigger a workflow for creating STO.
2. Configure it an EDI output for sales orders. Using the EDI document, create STO in the same system.
3. Create STO using BAPI from the sales order exit 'USEREXIT_SAVE_DOCUMENT'.
I am trying to understand the issues if I go with option of creating STO from sales order user-exit. I tested it and it is working fine. But what concerns is me transaction integrity. In other words I am trying to execute another transaction within a transaction. Both Transactions (VA01 and ME21N/BAPI) may be trying to access same tables. Anyways I havent see any potential overlap.
I would like to know anybody implemented such a solution?
What could be the potential issues? Does it really affect transaction integrity?
Thanks A Lot
Anil

I would also be concerned with the possibility of the order failing to update AFTER you call the BAPI. You could create a custom output type that processes on order create for that order type. You could add your BAPI call to the processing routine of the output type.

To exit from the while(1) loop

Hi all ,
I have a simple question that if in a callback function of a command button, i use a While(bLoop)
loop , where bLoop is a boolean variable initially set to TRUE, then how can i break or exit from this while Loop by using a control on the front panel , which exits the while loop by setting     bLoop = FALSE .
I have tried it but it is not exiting
Solved!
Go to Solution.

The problem here is that CVI normally only executes one callback at a time. While you are in one control callback, no GUI processing and subsequent calls to other callbacks normally occurs.
You can try the following approach - but it is not really the best method:
    while (b_loop) {              // Inside a callback
        ...                       // Perform your tight program loop
        ProcessSystemEvents ();   // Force CVI to see if any GUI controls need servicing
If you have a different control callback to clear the global b_loop, this quick-and-dirty approach might work for you.
You should only use this technique for very simple programs - it can rapidly spiral out of control and end up in a mess if you're not careful. NI recommends that you do not use ProcessSystemEvents() inside a control callback.

Accessing the Logon User Exit from the Internet using an ITS Service

I can access the Logon User Exit (EXIT_SAPLSUSF_001) from R/3, but not from the Web using an ITS service. What am I missing in order to access the Logon User Exit from the Web. The ITS service was created from an ABAP screen program.
Thanks
david yee

The SAPGui logon exit is called after successfull authentication has been completed and after a SAPGui session has been attached.
If you logon via RFC, WebGui, ICM or the Wgate then this exit does not trigger.
What are you wanting to add to your code after the logon ?
An solution I have used is to create a wrapper RFC for a BAPI and create a webservice for the wrapper. Before calling the BAPI you can do whatever you want to from a security perspective.
But for that you need to have an appropriate BAPI...
Please explain what you want to do and what you would have wanted in the exit. Often there is a better way.
Cheers,
Julius
ps: I moved this to the security forum.

EXIT from a user exit to intial screen of MM01

hi friends,
I am working on MM01 user exit..after saving user exit ll trigger..and in one scenerio we need to come back to screen MM01 with message at task bar..
Please give some idea ..
regards

well to come back to your initial screen is quite easy.
goto mm01 on your initial screen and hit F1.
in the help hit the button technical information.
there you get some information. amongst them your dynpro number of the screen you are on. (ahhh BTW make sure you place you cursor on the main screen before doing above steps, otherwise you get the dynpro-number of the subscreen your cursor is placed on.)
Then at the end of your user-exit write: leave to screen (your dynpro number you identified with the steps above).
to place a status message i believe you already have to be on the dynpro on which you want it to display. this would mean you had to modify the PBO event of that dypro, and i dont think you want that.
but i dont see any other solution. maybe some other dude will post something about that

How to exit from the DO-while loop in the event structure

Hi all
I am just a beginner for Labview
I want to build a loop in the event structure, but when I enter in the loop, it seems the system is dead, and I can't exit the loop.
here I attached a simple sample.
In the sample. when I press the start_calculation button , the calculation start, but the system is dead, and I can't exit calculation loop.
actually, i just want switch the different operation by changing the event action.
anybody has a good idea about it??
thanks so lot

Your problem is that you are trapped inside an event case. It is not a good idea to run extended code inside event cases, else the event structure cannot service other events.
Why don't you use the outer loop for everything? Now things don't step on each others toes. What good is an event structure if it cannot react at all times???
