Exiting from method in enhancement
Hi Experts,
I am enhancing a standard class method thought an exit point at the beginning of the method. When a certain condition is satisfied in the enhancement point I want to stop the processing further and exit the complete method.
EXIT will not work here as its only for a processing block. Any suggestions?
Thanks
AFAIK this is not allowed, else you could successfully replace the full SAP code by inserting in a pre-method or any start Implicit enhancement points any customer code and then exiting the form/method/module, that would not be an enhancement but a full modification of the standard SAP code and should require [SSCR key|http://service.sap.com/sscr ].
(For the same reason someone already posted a thread where he put an IF and ELSE in a first Enhancement and the ENDIF if another, good try, but SAP editor/enhancement builder didn't get fooled
You could only raise an error or error message to leave the processing block behind the enhancement (FORM, FM, Method)

Raymond

How to exit from method if there is any Error message
Hi All,
I have one button (Retrieve) and on that button I am calling a method(OnRetrive) and in that method i am calling func module and in that i am getting some messages.
<b>Now If that FM gives Error message then i have to exit from that method without processing further code.</b>
How can i do this? Help!!!
Expecting your reply ASAP.Use the RETURN statement. It will get out of your method.

In Pre-Exit, prevent method from being called
I have created an enhancment for a webdynpro component. Then, I have defined a pre-exit for a method in the component controller. Inside the pre-exit, I do a couple of checks, and depending on them, I would like to skip the processing of the method for which I have define the pre-exit. Is this possible?
I thought of the RETURN statement, but this won't help. RETURN will jump out of the pre-exit, but not out of the method.
my-pre-exit-of-method-SET_MY_VALUE.
IF some_condition = some_value.
"prevent the method SET_MY_VALUE from being called. but how??
ENDIF.
end-of-pre-exit.I just find out how to circumvent this...
The trick is to use "Overwrite exit". Add your own codes. Depending on your conditions, you can call back the original method. But when you call the original method, you need to use the syntax:
me->original_method(...)
Do not use:
wd_this->original_method(...)
Using "me" will only call the original method; using "wd_this" will trigger your overwrite exit which means this will jump to a recursive call to your own exit; This will certainly drain the resources of your system indefinitely until it dumps.

Remove screen exit from enhancement project
Hello Experts,
I am using using the EXIT: EXIT_SAPMM06E_012 of project MM06E005.
While activating the project in CMOD, by default screen exits associated will also get activated.
Please let me know, how to remove only screen exits from project.Hi ,
Just remove the fields in the screen and then deactivate the calling include.What is the business requirement.
Regards,
Madhu.

How to track exit from the PageFragment Lifecycle
Hi,
I have a requirement of keeping track of exit from a pageFragment.
My structure contains: a TaskFlow which contains a train . This train node contains the page Fragments. Now when i navigate from one PageFrag to another ie. when i exit the currently selected node having a page Fragment, i need to fire a logic.
I tried using creating a bean which implements RegionController interface which has refreshRegion(RegionContext ) method.I got hold of RegionBinding interface which has only one of the following values: Entry, Execute_Model, Prepare_Model, Refresh_Unknown, Render_Model and Type_executable_region.
Also in this case i am not exiting the TaskFlow during the navigation.
My doubt is how do i or can i use RegionController to keep track of exit from the currently rendered PageFragment's Lifecycle.
Also , can i use PagePhaseListener to keep track of the PageFragment lifecycle stage. (My understanding is PagePhaseListener is to be used for Jspx not Jsff). Plz do correct me if i am wrong.
Thanks,
Prasenjit

Edited by: user586616 on Aug 31, 2009 3:57 AMHi Frank,
I have created a ControllerClass which implements RegionController. I have registered the same as controller class in my pageFragments PageDef.
So, on navigation from one train node to another. due to post back call to leaving node and freshcall to the arriving node in the train flow. i am able to get the leaving as well approaching node.
My doubt is can i get similar or better control over the nodes traversed using trainModel or anyother adfinternal controller class? Kindly suggest any better way of getting handle to the navigating train nodes.
Sample Code which i have implemented:
public class RegionControllerBean implements RegionController {
public boolean refreshRegion(RegionContext regionContext) {
System.out.println("**********************************");
System.out.println("inside refreshRegion method call");
String selectedView = ControllerContext.getInstance().getCurrentViewPort().getViewId(); ------> this gives me the handle to the viewId of the curently selected pageFragment
System.out.println(ControllerContext.getInstance().getCurrentViewPort().getViewId().toString());
String pageName = selectedView.split("/")[2];
System.out.println("Current PageName:"+pageName);
System.out.println("name: "+regionContext.getRegionBinding().getName());
int refreshFlag = regionContext.getRefreshFlag();
if(refreshFlag == RegionBinding.PREPARE_MODEL){
System.out.println("Inside prepare Model phase"); ------> on entering of that node i need to call some logic before prepare_model phase
if(refreshFlag == RegionBinding.EXECUTE_MODEL){
System.out.println("Inside execute model phase");
if(refreshFlag == RegionBinding.RENDER_MODEL){
System.out.println("Inside render model phase");
// propagate refresh to inner binding container
regionContext.getRegionBinding().refresh(refreshFlag);
return false;
public boolean validateRegion(RegionContext regionContext) {
// propagate the validate to inner binding container
System.out.println("inside validate region method");
regionContext.getRegionBinding().validate();
return false;
thanks,

How to exit from a WebDynpro ABAP application and open another url
Hi Friends,
How to exit from a WebDynpro ABAP application and open another url like (www.yahoo.com) in the same window of the WD4 application on click of a Button?
Regards,
XavierHi,
First of all you should create outbound plug in the window you are trying to exit with plufg type "Exit"
Then create method handler in the view with this code
data lo_view_cntr type ref to if_wd_view_controller.
data lo_win_cntr type ref to if_wd_window_controller.
data: l_parameter_list type wdr_event_parameter_list,
l_parameter type wdr_event_parameter,
l_val type ref to data,
l_val_url type REF TO data.
field-symbols: <fs> type any,
<fs_url> type any.
lo_view_cntr = wd_this->wd_get_api( ).
lo_win_cntr = lo_view_cntr->get_embedding_window_ctlr( ).
CREATE DATA l_val type c.
CREATE DATA l_val_url type string.
ASSIGN l_val->* to <fs>.
ASSIGN l_val_url->* to <fs_url>.
<fs> = 'X'.
<fs_url> = 'http://your-link.com'.
l_parameter-name = 'URL'.
l_parameter-value = l_val_url.
INSERT l_parameter INTO TABLE l_parameter_list.
lo_win_cntr->if_wd_view_controller~fire_plug( EXPORTING plug_name = 'EXIT_PLUG'
parameters = l_parameter_list ).
You can easily change this logic to exit application instead of redirecting to the site
just changing to
l_parameter-name = 'CLOSE_WINDOW'. -
EmptyStackException when exit from nested page flow on SP2

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.

How to exit from the class execution process?
I am invoking an exe from my Java application using the Runtime.getRuntime().exec() method.
though the process is completed, the class is still running.
how do i exit from the class execution, but with the process still running??To sabre150 :
I am directly executing the command through the exec() method:
Runtime.getRuntime().exec("...../iexplore.exe");This way, the control is going to the opened IE window and only on closing it, my class is exiting.
Is there any other way where I can come out of the class, but ensure that the process which i run through the exec() method, is still running? -
How to pass one value from method 1 to method 2 in BADI...
Hello Experts,
How do I pass a custom variable from lets say method 1 to method 2 in BADI? Do I need to
enhance it? For example, I need to pass my flag variable which contains 'X' from method as exporting
and importing in method 2.Hi,
Yes declare a flag in first method and make it 'X' when you get the condition that you have made changes to item values and export it to memory id ...
EXPORT GV_FLAG TO MEMORY ID 'SSS'.
and in second method import the same...
IMPORT GV_FLAG FROM MEMORY ID 'SSS'.
and according to the value write the logic...
Thanks,

KEPM planning method "customer enhancement"
Dear all,
I want to use the planning method "customer enhancement" in transaction KEPM. The planning level has been defined as well as the corresponding planning package. I also activitated the user exit COPA0006 which is behind this enhancement.
When executing the planning method no data are selected and as a result the user exit is not performed. If I use the same planning package but a different method (e.g. copy) data will be selected and the method is executed.
Does anybody have any experience with the user exit COPA0006?
Thanks a lot in advance
Best regards DorotheeIt worked when I created ran the integration model for a Pur Info record. I guess this works only if we had a source list ( as briefly touched upon in the BADI documentation). If any one has a different take on it, please share with me and I will really appreciate it.

Gracefully exit from a Linux kill
Is there a way to gracefully exit from a Linux kill command?
Given the following code:
public static void main(String[] args) throws IOException
boolean bExit = false;
while (!bExit)
try
Thread.sleep(1000L);
catch (InterruptedException ex)
bExit = true;
System.out.println("Program exiting gracefully.");
}Is there a way for the Linux kill command to make the message "Program exiting gracefully." appear?Certainly not for kill -9.
But you can look at Runtime.addShutdownHook().The problem I have with Runtime.addShutdownHook() is (from the API Javadoc):
"Shutdown hooks should also finish their work quickly. When a program invokes exit the expectation is that the virtual machine will promptly shut down and exit. When the virtual machine is terminated due to user logoff or system shutdown the underlying operating system may only allow a fixed amount of time in which to shut down and exit. It is therefore inadvisable to attempt any user interaction or to perform a long-running computation in a shutdown hook."
I just was wondering if there was a built-in hook for the kill command like the hook for "kill -3" that calls the Thread.interrupt() method on the main thread of execution.
My actual code is more like:
public static void main(String[] args) throws IOException
boolean bExit = false;
SubThreadManager1.init();
SubThreadManager2.init();
while (!bExit)
try
Thread.sleep(1000);
catch (InterruptedException ex)
bExit = true;
// After these shutdown methods are called it could take up
// to 30 seconds before they reach the stopped state.
SubThreadManager1.shutdown();
SubThreadManager2.shutdown();
while (!SubThreadManager1.isStopped() || !SubThreadManager2.isStopped())
try
Thread.sleep(500L);
catch (InterruptedException ex)
System.out.println("Program exiting gracefully.");
}I was just simplifiying the test case to get the point across.
