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

Event triggering from a class to parent

Hi,
             I am trying to write a custom class for image loading.
public function imageLoader(url:String, mc:MovieClip):void {
                              loader = new Loader();
                              loader.load(new URLRequest(url));
                              mc.addChild(loader);
                              loader.contentLoaderInfo.addEventListener(Event.INIT, initListener);
                              loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progressListener);
                              loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadListener);
                    public function initListener(e:Event):void {
                    public function progressListener(e:ProgressEvent):void {
                    public function loadListener(e:Event):void {
I ll get the events in these listeners in the loadImage class. But i want to trigger a function in the calling class or root or stage, when these loader events are fired.
How this can be done?
Regards,
Sreelash

the ImageLoader class should extend EventDispatcher
you cna then redispatch the events wihtin the ImageLoader class
e.g.
public function initListener(e:Event):void {
     dispatchEvent(e);
then in the parent class you will have a reference to the ImageLoader class and you can add event listeners there
e.g.
var imageLoader:ImageLoader = new ImageLoader();
imageLoader.addEventListener(Event.INIT, somefunction);
imageLoader.load("image", this);
or something alone these lines depending on how you want to structure things

Function module equivalent to SWE_EVENT_CREATE while using ABAP classes

Hi there,
I used to use SWE_CREATE_EVENT to fire the events linked to my BOR objects, in order to start certain workflows.
Now I am using ABAP classes within the WorkFlows, and the name of the classes MUST (in my case) be longer than 10 characters, and SWE_EVENT_CREATE is cutting the name so it does not work
Do you know any FM equivalent to start an event from a ABAP class (SE24) object?
I have tried to use SAP_WAPI_START_WORKFLOW, but I cannot find the way to include my object in the container. Any ideas on this point would be welcome as well
Thanks so much,
Miguel

Thanks for such a quick reply,
You were right. I actually did follow Jocelyn's blogs, but somehow I skipped the raising event section.
Just for information, the URL with the solution to this problem is:

Events Triggered

hi
guys i am not understand why the out put is 1,2,99.
please explain me
Events Triggered in the Order Dictated by the Driver Program
1 report ztx1702.
2 data f1 type i value 1.
3
4 end-of-selection.
5    write: / '3. f1 =', f1.
6
7 start-of-selection.
8    write: / '2. f1 =', f1.
9    f1 = 99.
10
11 initialization.
12   write: / '1. f1 =', f1.
13   add 1 to f1.
output:
1. f1 =          1
2. f1 =          2
3. f1 =         99
thanks

Hi Sanjeev,
Order of events triggered in ABAP programming is..
     INITIALIZATION
     AT SELECTION-SCREEN
     AT SELECTION-SCREEN ON <field>
     START-OF-SELECTION
     TOP-OF-PAGE
     END-OF-PAGE
     END-OF-SELECTION
ABAP program will be executed in the above event order, with out depending on the order you write.
Your program execution will be like this..
1) It declares the f1 as the integer type value and initializes 1 to it.
2) It directly goes to the Intialization part and there you are printing f1 value which is 1.
So there the output will be 1.f1 = 1.
At step 13 It will add 1 to f1. so here your f1 value is 2.
3) It then goes to the Start-of-selection event.
   Here you are again printing f1 value which is 2.
   after printing f1 value you are assigning 99 to f1 so your f1 now becomes to 99.
4) It goes to End-of-selection part and again you are printing f1 value which is 99.
So your report output willbe like this..
1.f1 = 1.
2.f1 = 2.
3.f1 = 99.

Sreekanth.

Calling Portal event from ABAP class

Hi Experts,
I need a following clarificatrion, Please help,
1. Is it possible to call a webdynpro method from a normal ABAP class?
2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
3. Is there any ways with which we can call portal event from ABAP class?
Thanks,
Shabir

>1. Is it possible to call a webdynpro method from a normal ABAP class?
I wouldn't necessarily recommend this approach. You shouldn't try to trigger events or any of the standard WDDO* methods from outside the WD Component itself. That said, you can pass the object reference (like the WD_COMP_CONTROLLER object reference or the View Object Reference) into methods of normal classes. Be careful if you are finding yourself calling a lot of your added methods from outside WD. This is probably a sign that these methods should be in the Assistance Class or some other Class functioning as a Model Object.
>2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
What exactly do you want to do here? Do you just want to get the relaxation script? For what purpose? You should never need to inject the relaxation script into WDA.
>3. Is there any ways with which we can call portal event from ABAP class?
To what purpose. Do you just want to delegate the triggering of the event that is inside WD Component to be called from a class? If so you can pass the portal API object reference into a class from the WD Component. However this only works while running within WD.
How is this class used? Are you running in WD? Are you trying to generate some HTML code that runs in the portal independent of WD?

CLBUS1007.created event triggered by an ABAP OO event?

Hello gurus,
I have noticed, that when the customer master is created in ECC 5.0, the CLBUS1007.created event is triggered (SWEL). However; CLBUS1007 object does not exist in the BOR directory. It must be ABAP OO event than, right? If so, how can I find out the corresponding class? I wonder how I can make a binding, check object attributes etc.
By the way, BUS1007 is obsolete in BOR. Do you know if I should use some other BOR object for a Customer or create a sub-class of this ABAP class that I don't know yet?
Regards,
Michal
PS. I know there is very good blog by Jocelyn Dart about this topic (/people/jocelyn.dart/blog/2006/07/27/raising-abap-oo-events-for-workflow), but it does not solve my problem of relation between SWEL object type and ABAP class.

Hi Michael,
If you look at the header of BOR object BUS1007 you'll notice the last time this was changed was back in 1999 - i.e. 4.6a. So that object has been dead for quite some time.
It's almost certainly just an obsolete piece of code that hasn't been cleaned up properly. I suspect what is happening is that it is mix and matching the object category CL with the business object BUS1007 (which of course is category BO).
Either that or its an obsolete configuration entry that's getting picked up.
If it's annoying you, you could try putting a session breakpoint on function module SWE_EVENT_CREATE to see if you can track the call that causing the problem, and then of course report it in (Low priority) to get it cleaned up.
If you are just looking for the correct object to use, suggest you report it in anyway as a query... I notice they haven't bothered to specify the new object type in the documentation but if you look at SAP note 719936 it mentions that the new object type is KNA1 - which definitely is in the BOR directory.
I haven't seen an ABAP OO version of KNA1 yet in any of the systems... HR seems to be doing a fair bit in ABAP OO though.
Hope that helps.
Regards,
Jocelyn

Create an event using abap class (transaction swetypv)

Hi,
Im trying to create an event by using an abap class.
The purpose is to update po reqs using BAPI_REQUISITION_CHANGE upon saving a sales order. The exit is called on saving a sales order MV45AFZZ.
In MV45AFZZ the method cl_swf_evt_event is called and the object type, event, objkey and obj cat is exported.
Object Type = ZBUS203200
Event = Z_TRAD_ORDER_CHANGE_OO
I created my class ZCL_UPDATE_PUR_REQ (by copying CL_SWF_RUN_WIM_HANDLER
And using interface name BI_EVENT_HANDLER_STATIC )
In /nswetypv I assigned Class ZCL_UPDATE_PUR_REQ
to Object Type ZBUS203200
And Event Z_TRAD_ORDER_CHANGE_OO.
All that works fine except for passing in the objectkey.
In Class ZCL_UPDATE_PUR_REQ
Method BI_EVENT_HANDLER_STATIC~ON_EVENT
When I go to create a parameter for object key, I get the message
Parameters/exceptions of inherited methods or events cannot be changed.
Has anyone any suggestions for how I can get the object key into the method call BI_EVENT_HANDLER_STATIC~ON_EVENT?
Thanks

Hi Johann,
You don't need a class to do the job if you are on a 6.10 or higher system. Use command CALL TRANSFORMATION to create an XML from an internal table.

Abap-Class-Event in Wait Step

Hi guys,
in my workflow i have an activity with an abap method. This method works like a dialog. This means, i get a workitem in the business-workplace which shows a webdynpro where a pdf is displayed and where i can choose whether i click on button1 or button2.
When i click on one button, an abap-class event will be created. This event has a container. My target is, to bring the user desicion back to the workflow via event.
When i start a new workflow with this event then it works fine. But i dont want 2 workflows. I need a solution with one workflow. So i use a fork in my workflow. In branch 1 i have the activity which displays the pdf and create the event. In the other branch i have a waiting step, which waits for the event and bring the user-desision from the event-container to my workflow-container.
That was my plan, but it dont works this way. I checked the event-trace and theres no receaiver entered for my event. So my workflow stoped at the wait-step (wait step is ready).
I read, the the workflow system is automatikly doing the type-linkage and the instance-linkage, but i found only the instance-linkage filled. Can it be, that the wait step is only working with BOR-Events?
Any ideas?

Hi swangir,
i tryed this FW SAP_WAPI_WRITE_CONTAINER some days ago. I can use SAP_WAPI_READ_CONTAINER easylie but when i try to modify the container then i get an enqeue exception in the SAP_WAPI_WRITE_CONTAINER FM. I guess this came up, because i call the webdynpro from an activie-step in the workflow and not a dialog-step. So i guess the container is locked and i cant write. I also tried to unlock it with dequee_e_ .. FM i forgot the name. But it also didnt work.
Thats why i tryed to bring the user desision via event back to the workflow. And it works, as long i use 2 workflows, like i explained in my first post.
What do u mean with...
"Alternatively, you can bind back the class event container to workflow container by binding back from the dialogue step."

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.

Use of Events in OOPS ABAP

Hi all,
Can anybody please say me what is the exact use of EVENTS in OOPs ABAP. Can anybody please explain me with an example.
Thanks in advance.

hi,
By triggering an event, an object or a class announces a change of state, or that a certain state has been
achieved.
Events link objects or classes more loosely than direct method calls do. Method calls establish precisely
when and in which statement sequence the method is called.
However, with events, the reaction of the
object to the event is determined by the triggering of the event itself.
Events are most often used in GUI implementations.
Other external object models, such as COM, ActiveX Controls etc, also provide events.
At the moment of implementation, a class defines its
instance events (using the statement EVENTS) and
static events (using the statement CLASS-EVENTS)
Classes or their instances that receive a message when an event is triggered at runtime and want to react
to this event define event handler methods.
Statement : (CLASS-)METHODS <handler_method> FOR EVENT <event> OF <classname>.
These classes or their instances register themselves at runtime to one or more events.
Statement : SET HANDLER <handler_method> FOR <reference>. (for instance events)
SET HANDLER <handler_method>. (for static events).
A class or an instance can trigger an event at runtime using the statement RAISE EVENT.
Both instance and static events can be triggered in instance methods.
Only static events can be triggered in static methods.
Events can only have EXPORTING parameters which must be passed by value.
Triggering an event using the statement RAISE EVENT has the following effect:
the program flow is interrupted at that point
the event handler methods registered to this event are called and processed once all event handler methods have been executed, the program flow starts again.
If an event handler method in turn triggers an event, then the program flow is again interrupted and all event handler methods are executed (nesting).
Events are registered using the command SET HANDLER. Registration is only active at program runtime.
Events cannot be persistent.
You want to register an object to an event belonging to another object. The SET HANDLER... statement
enters the registration in that objects list. All handlers for one event are entered in this list.
When the event is triggered, the list shows which event handler methods need to be called.
Event handler methods are triggered by events (RAISE EVENT), although they can also be called like
normal methods (CALL METHOD).
The interface of the event handler method consists solely of IMPORTING parameters. Only parameters
from the definition of the corresponding event (event interface) can be used.
An event interface only has EXPORTING parameters and is defined using the EVENTS statement in the declaration of the event. The
parameters are typed in the event definition and the typing is passed to the event handler method, that is,
the interface parameters of the event handler method cannot be typed in the definition of the event handler
method.
In addition to the explicitly defined event interface parameters, the implicit parameter SENDER can also be
listed as an IMPORTING parameter for instance events. This passes on a reference to the object that
triggered the event.
Events are also subject to the visibility concept and can therefore be either public, protected or private.
Visibility establishes authorization for event handling :
all users only users within that class or its subclasses
only users in that class.
Event handler methods also have visibility characteristics. Event handler methods, however, can only have
the same visibility or more restricted visibility than the events they refer to.
The visibility of event handler methods establishes authorization for SET-HANDLER statements: SET
HANDLER statements can be made anywhere in that class and its subclasses only in that class

ABAP class in task

Hello,
I'm using a ABAP class in a task, but when I triggers the workflow in this step its gets blocked with the status "in process".
The abap class is public and the method that I'm calling is static, Also I have implemented the IF_WORKFLOW interface to use from the task.
Do you have any sugestion about this to don't get block?
Thanks

Hello Diego,
when using class-based tasks, most exceptions thrown during the prepare and execution steps are generally caught and not beeing forwarded into the workflow log, especially when there's a general problem with the method definition.
In this particular case, the execution of static methods probably runs into an exception, as an instance is (accidently) required, even though -- by definition -- the method is instance-independent. For sure, class methods cannot be called as functional methods in container operations. Possibly the method was instance-bound at the time, the task was created, and later on changed to a class method. Re-Creating the task could be helpful here. Otherwise pass an instance to the task container (event though not required) and let the runtime system have it to call the class' method.
With the very best wishes,
Florin

BOR or ABAP Class for MM41

Hi all.
I am wondering whether anyone ever use workflow in transaction MM41.
Does SAP provide standard BOR or ABAP Class for transaction MM41.
I know there is BUS1001006 but this only get triggers from MM01.
Does user exit or BADI is the only way to trigger workflow from MM41?
Thanks

Hello,
It might help if you said what MM41 was.
As usual, turn on the event trace (SWELS), create and save something in your chosen transaction and then check the event trace (SWEL) for any events.
