Event Triggering method in BW

Hi All,
Step1: I want to run a ABAP Program.
Step2: I wany to trigger one infopackage.
My porblem is I want to execute Step2 only after successfull ofStep1.
Iam able to run Step2 for one time, But in my case I want to run the both steps as a periodic daily.
Thanks in advance.

In your Infopackage, on the Schedule Tab, flag "Start Later in Background".
Change the start condition to execute "After Event", and make sure the <b>Periodic flag</b> is set.
Then create a job in SM36 which calls your first ABAP program and then calls another ABAP program that triggers the event.
To create an ABAP program to trigger an event see this link:

Button's Event Handler Method not getting triggered

To add a button I have written the following code:
clear ls_button.
    l_import = 'Mass Upload'.
    l_enabled = 'X'.
    clear ls_button.
    ls_button-on_click = 'UPLOAD'. "IMPORT FILE
    ls_button-text     = l_import.
    ls_button-enabled = l_enabled.
    INSERT ls_button INTO rt_buttons INDEX 5.
Created a new Event Handler method for it and wrote the following code:
gr_file_popup = comp_controller->window_manager->create_popup(
    iv_interface_view_name = 'ZSRQM_INCID_H/FileUploadwindow'
    iv_usage_name = 'ZCufileupload'
    iv_title = l_title ).
gr_file_popup->set_on_close_event( iv_view = me iv_event_name = 'upload' ).
gr_file_popup->open( ).
When i run in th component in debug mode,my event is not getting triggered.
Please suggest.

Najam

Try the following code in first part...
clear ls_button.
    l_import = 'Mass Upload'.
    clear ls_button.
    ls_button-on_click = 'UPLOAD'. "IMPORT FILE
    ls_button-text     = l_import.
    ls_button-page_id = me->component_id.
    ls_button-enabled = abap_true.
    INSERT ls_button INTO rt_buttons INDEX 5.

Class or method needed to capture the event triggered

Hi All,
       Help needed in finding the event triggered in ALV container.
As per my requirement , I am registering the event mc_evt_modify for getting the search help(MEKK) in a ALV container . However it is triggered when ever I am inserting a row in ALV container and also the method data_changed is also triggered with that. But I don't want the method data_changed to be triggered.
Is there any method or class which captures the event triggered so that I can put a condition on mc_evt_modify event.
Please help me to resolve this issue.

Enhance standard class with event handler method

In trying to enhance a standard class with a new event handler class, I find that the ECC 6.0 EHP4 system does not appear to recognise the fact the method is an event handler method. The specific example is a new method to handle the event CL_GUI_ALV_GRID->USER_COMMAND.
I notice that the flag called Active has not been ticked - see image below. Perhaps this is the reason why the event handler is not being triggered.
Note that there is an event handler for the same event in the standard class which obviously is executed as expected. Any ideas on limitations in the system or I am missing a step?
Thanks
John

Thank you for your replies.
There is a bug in the ALV handler of a standard SAP class (when executed in ITS WebGUI) and I was hoping to create a custom event handler as an Enhancement to execute some custom code to sort of "handle the bug".
I agree - ideally it should be done in a Z class but that will not give me access to the object methods and attributes of the enhanced class.
Cheers,
John

Event triggered for checkbox in cl_gui_alv_grid

Hi All ,
I have a requirement like ,i give PO number on selection-screen.After execution, the items should be displayed on second screen ,which has some options on the top like before GR or after GR .(custom screen designed with cl_gui_alv_grid for display)
I desgined checkboxes for each row of the line item.user can click on multiple rows and click on EXECUTE button on the screen.After that smartform should trigger and print .
Now my query is how to capture the checkboxes which the user has entered (thru cl_gui_alv_grid) . Is there any event that gets triggered upon clicking the checkboxes?? I need the data of the corresponding row to process further .User can click on multiple items.
Please respond
Thanks

Hi Hemanth
You should have a field in your internal table matching the checkbox column in ALV.
Call method CHECK_CHANGED_DATA of CL_GUI_ALV_GRID on user command for execute button,
it will set the field = 'X' for ticked lines in your internal table.
Then use a loop on your internal table and find selected lines.
You don't need an event triggered when user clicks.

Event handler method

Hi all,
I want to know the significance of creating event handler method in Class builder.
and how it can be used at the time of event trigger.( Is it called automatically or programmer need to call it explicitly in the program.)
Thanks,
Sushant singh

Hi Sushant,
1. 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.
2.To trigger an event, a class must
Declare the event in its declaration part
Trigger the event in one of its methods
3.You declare events in the declaration part of a class or in an interface. To declare instance events, use the following statement:
EVENTS evt EXPORTING... VALUE(e1 e2 ...) TYPE type [OPTIONAL]..
4. An instance event in a class can be triggered by any instance method in the class. Static events can be triggered by any method. However, static methods can only trigger static events. To trigger an event in a method, use the following statement:
RAISE EVENT evt EXPORTING e1 = f1 e2 = f2 ...
5. Events are handled using special methods. To handle an event, a method must
be defined as an event handler method for that event
be registered at runtime for the event.
Declaring Event Handler Methods
Any class can contain event handler methods for events from other classes. You can, of course, also define event handler methods in the same class as the event itself. To declare an event handler method, use the following statement:
METHODS meth FOR EVENT evt OF cif IMPORTING e1 e2 ...
6. Registering Event Handler Methods
To allow an event handler method to react to an event, you must determine at runtime the trigger to which it is to react. You can do this with the following statement:
SET HANDLER h1 h2 ... [FOR]...
It links a list of handler methods with corresponding trigger methods. There are four different types of event.
7. Timing of Event Handling
After the RAISE EVENTstatement, 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.

VMware Performance Event Triggers use case questions.

1) Can the CPO VMware Adapter Performance Event Triggers and their
SAMPLE SIZE, INTERVAL, and CONDITIONS attributes be configured
for the following use case?
2) Can VMWare Performance Event Triggers be CORRELATED? and if so would it be needed to satisfy the use case?
3) Would an additional performance monitoring tool be required to satisy the use case?:
If a VM CPU or RAM has been 80% for 2 hours then trigger a workflow
and
If a VM CPU or RAM has been at 60% for X days then trigger a workflow

I will first describe how you could instrument a correlation method, but ultimately, I'm not sure it is really necessary for the uses cases described.
To correlate VMware performance events over a designated timeframe, you would create a correlation process that tracks the underlying performance event and decides whether or not to trigger the process you want triggered when the correlated event is detected.
Here's how it works.
First, create a global table with three columns:
1) Virtual Machine path
2) Consecutive Trigger Count
3) Last Trigger time
Create a process that is triggered by a VMware performance event (such as Memory Avg > 80%) where you can set a sample size and interval that makes sense given the timeframe of interest (2 hours or X days). For example, a sample size of 10 and interval of 30 seconds (5 minutes) is a reasonable time slice from vCenter for a 2 hour timeframe. This results in requiring 24 consecutive triggers to raise the actual event of interest. (2 hours divided by 5 minutes)
That is, the formula is:
Sample Size * Interval / Timeframe = Consecutive Trigger Count
The correlation process triggered by the raw VMware event does the following:
1) If there is no existing entry in the global table for the VM, add entry to table with count = 1 and current time
2) if entry exists, check the current time against the last trigger time
   a) if it is the next interval, for example, current time is 12:15 and last triggered time was 12:10 (see note below),
        Increment counter and set last trigger time
        If count = 24, then run the process that handles the "VM Memory Avg > 80% for at least 2 hours " and delete entry from table.
       If count < 24, the process exits having only incremented the counter and set the last trigger time
   b) if the current time is > than last trigger time + time slice (+ a little padding), set the counter back to 1
Note: When comparing current time w/last time, you should pad to account for slight processing delays so compare current-time < last-time+(time slice*2). Anything less than 10 minutes in this case would be considered a consecutive trigger. You could also compare current-time < last-time+time-slice+1, which is probably also safe.
Now, having gone through all that, you may not need the correlation process after all. Simply adjust your sample size to be large enough to accommodate your ultimate timeframe and you can trigger your event handler directly without the need to correlate. So for the 2 hour window, just create a sample size of 240 (* 30 seconds = 2 hours). This may or may not work depending on how performance metrics have been configured on the server (sample size, intervals and how much is saved). You can only set your own sample and intervals to multiples of those configured values (so be careful and refer to the VMware documentation when relying on such metrics)
You may find that the correlation method I first described is more reliable, especially for longer timeframes such as X days (where you need to sample hourly rather than every 5 minutes).
In any case, I think you can do what is asked without external monitoring, but it will require some experimentation and a deeper knowledge of how performance metric sampling works for ESX.

How to disable the "turn page" event triggered by the scroll/swipe function?

The problem is as follows.
The default behaviour of Acrobat Reader (both stand alone and browser plug-in) is to allow scrolling/swiping with the mouse wheel/trackpad. This is useful when the pdf's page length is greater than the screen's own length, because you can read the pdf with no need to distract your attention from the text to the scrollbar button. However, the same scroll/swipe function turns into a usability problem when the pdf is embedded in a html page and the pdf's page length is smaller than the browser's length. In this case, the scroll/swipe turns the page, distracting your attention from the text to the unintended behaviour of the browser. What happens is that you are so used to scrolling/swiping that you did it unintentionally in the pdf's caption area. You really did not want to turn pages in the pdf. Furthermore, if the pdf takes the whole html page, being a website, the scroll/swipe function flips the website pages in ways that neither the reader nor the writer had ever intended. Hence the question. How to disable, in this case, the "turn page" event triggered by the scroll/swipe function? A JavaScript should do, but the SDK documents did not help so far...

How to Call Event Handler Method in Another view

hi,
1)    You can make the method EH_ONSELECT as public and static and call this method in viewGS_CM/ADDDOC using syntax
    impl class name of view GS_CM/DOCTREE=>EH_ONSELECT "method name.
             or
2)The view GS_CM/ADDDOC which contains EH_ONSELECT method has been already enhanced, so I can't execute such kind of operation one more time.
                     or
3)If both views or viewarea containing that view are under same window , then you can get the instance ofGS_CM/DOCTREE from view GS_CM/ADDDOC through the main window controller.
lr_window = me->view_manager->get_window_controller( ).
    lv_viewname = 'GS_CM/DOCTREE '.
lr_viewctrl ?= lr_window ->get_subcontroller_by_viewname( lv_viewname ).
Now you can access the method of view GS_CM/DOCTREE .
Let me know in case you face any issues.

View not copied or enhanced with wizard Error while creating Event Handler method in Z Component

Hello Friends,
In one Z Component (Custom Component), in one of the views, while creating event handler, it gave me error message that view not copied or enhanced with wizard.
I am aware that in Standard Component, if we want to create the event handler method then we need to first Enhance the Component and then we need to enhance the view.
But, in the Z Component (Custom Component), how to create event handler method in one of the views as while creating event handler method i am getting view not copied or enhanced with wizard error.

Hi,
Add a method in views impl class with naming convention eh_on__* with htmt and html_ex parameters. I dont have have the system right now. Please check any existing event import export parameters.
Check out do handle event method in the same class.
Redefine that method. Call that event method in this handle method. See existing code for reference.
Attach that event to the button on click event in .htm page.

Event triggering by abap class & ISR

hi gurus
1 ) can i able to see the event triggering by abap class in SWEL ? ,
2) in custom ISR scenario , new form scenario has been created by our functional consultant , and asking me to trigger a workflow for approval , when employee fills that particular ISR FORM , workflow should start and to go his HR administrator , when HR administrator double click on workitem he should get the ISR form in display mode & also with some descpition text is to be added in the screen (like user decision description ) with approval button ..... my question is how to trigger a event from in form scenario ? , how to bring the FORM screen to display mode to the HR administrator ?
regards
surya

Hi Surya
The BO for ISR forms is BUS7051 - Notification. Turn on the trace via SWELS and create a PCR/ISR form and you should see the events being triggered in SWEL.
Good Luck

Bug in scrollbar event triggering?

In LabVIEW 8.6, I am trying to fire an event when I finish moving the scrollbar of an array indicator. I use the "mouse up" event to avoid having the event structure fire constantly the entire time I am moving the scrollbar. However, there seems to be a bug (?) in the event detection. It works fine as long as I have the mouse on top of the scrollbar when I release it. However, Win XP allows you to continue to move the scrollbar even if the mouse is off to the left or right of the bar (when you click on the scrollbar it "locks" the focus onto it). However, LabVIEW does not seem to realize this and if I have the mouse slightly off to the right of the scrollbar when I release, the event doesnt fire. LV seems to base the event off of whether the mouse is on top of the pixels of the indicator rather than whether I still have control of the scrollbar.

Technically it is not a bug. There is no event triggered because when you do the Mouse Up, you are no longer on the scrollbar. Unfortunately, the behavior in Windows that allows you to continue to move the scrollbar even when you aren't on it is conflicting with the desire to detect when you let go of the scroll bar.
There was a recent thread discussingthis very issue and a way to get the behavior you are looking for.

You should ask your instructor to answer your questions rather than allowing them to turn the whole class of students loose on the forums usually asking the same identical question.
At least in your case, the question is different from most we've seen. Unfortunately, you haven't asked a clear enough question for us to understand what you are talking about.

Event Triggers not getting executed

I'm having following code in beforeData(PLSQL) event trigger:
ADCPackageName.MethodName
There is no such package in database, even my report works fine and publish data without any error.
Is there any configuration for enabling event triggers.
I didn't sufficient documents on event triggers. I want to use them for returning some values to report variables and validating input parameters.

Hi,
I tried to use "SAP_WAPI_CREATE_EVENT" also but it is also behaving in the same manner.
At first execution event is getting triggered but my workitem is not getting terminated.
But when i am executing the same report second time, again my event is getting triggered, and this time my workitem got terminated, and workflow proceeded furthur.
I checked it from SWEL, i have two entries for my event (i.e; first and second execution of report).
Any idea why it is behaving like this.
Please find below code for reference, apart from below code i have only declarations.
call function 'SWC_ELEMENT_SET'

    element       = 'ActualState'
    field         = 'A'
