Terminating event and abap oo class

Hi, gurus,
I 'd like to know how the terminating event works.
for example, i define a custom abap oo class (which has been implemented the interface of IF_WORKFLOW), and i want to use it as the terminating event of a standard task.
could you please tell me how does it works?
1. there must be an instance defined in the container of the task?
which must be instanciated in the run time?
2. then in another abap report, i simply raise the event defined as the terminating event, using the same key, then the pending task will be terminated?
could you pls provide more information on this ?
thanks and best regards.

Hi Jun Zhang,
An event that is used to stop a workflow or task, or change the behavior of an already started workflow is called Terminating Event.
If the event linkage is active and the linkage rules are satisfied, the status of the work item is set to COMPLETED.
Defining Event Linkage Terminating event linkage consists of 2 parts.
Type linkage which specifies business object type, event name, generic name for event receiver (WORKITEM for terminating events of tasks or EVENTITEM for wait for event steps)
Instance linkage which identifies the particular receivers (I.e. work item Ids) per object instance.
Terminating event linkages can be seen in SWE3.
For terminating events, along with Business object and Event a Container Element should be specified that holds the Object Instance.
Terminating Event for Workflow is available from Release 6.10 only. This is defined in Basic Data of Workflow Builder.
Binding Definition is optional for Terminating Events. Binding can be defined b/n event container and workflow container to pass event information to the workflow if required. That is the only way of passing information from an asynchronous method to the task that started it.
Thanks and Regards,

Use of events and interface in class

Dear All,
Could you please explain why we use events and interface in class.
Also please tell me the use of TRY and ENDTRY.
Regards,
Amar

Events may be a way of communication b/w classes. Imagine you want to call certain code from one class, you would need for that public method, but you don't want to expose it to external user. So you may use events for that. Also events are used to notify that certain state of class has changed (tiggering event). Then all handlers of this event executes and react accordingly.
Interfaces are a way of provide a service to class which implements it. Imagine that you have class office and hotel and gas station . They don't seems to have something in common. However, there can be some external energy provider which will be an interface. Each class which want to have a lease with this energy provided can implement it (the implementation can differ in some way), so he can provided energy to different classes. This way you will achieve polimorphism (meaning you call one interface method, but code behind it differs from class to class).
Interfaces are also means of multiple inheritance. One class can implement several service (interfaces). In contrary it can oly inherit from one class.
Try endtry are just new way of handling exceptions .
Try to search a litte bit you will find lots of info on the above.

Custom Events and Listeners between classes

I've got a project I've been working on for weeks that I'm
having yet another problem with. I'm trying to learn AS3 which is
why it's taking so long but that's not important for this post.
I wanted to create a custom event class so that I could make
sure the event does not interfere with other "COMPLETE" events that
are being passed between classes. In other words, I have a few
things that need to complete prior to a function being called...
one is some XML being loaded and another is a font loaded. So, I
thought I would create a custom FontLoaded class that extends Event
and make the type something like "FontLoadedEvent.LOADED". That way
I could listen for the XML "Event.COMPLETE" and this font event
also.
Please tell me if I'm going down the wrong path here but I
don't seem to be getting the dispatched event for my new custom
event. Also, how does one detect if it's being dispatched other
than if the eventListener is fired? Any other ways to test
this?

You can trace the event to see if it dispatched.
Also, this is not a good case to create a new event. Custom
events are used to store additional information. MouseEvent exists
because Event doesn't have localX, localY, etc. properties. Since
you don't seem to be throwing additional properties, you can use a
regular event.
trace(dispatchEvent(new Event("panelFontsLoaded"));
addEventListener("panelFontsLoaded", onFontsLoaded);
Static consts are used to help debug typos. The event type is
just a string, often stored in a const.

Terminating event 'Created' in ABAP OO context

Hi,
I need a little help here. A lot of times I have used terminating event ‘Created’ for different BOR types – and asynchronous tasks where users are asked to create an object using call transaction from a work item.
Now I am struggling with the same in ABAP OO and have an issue:
The goal is to have a terminating event raised on a custom class - and received by a work item if a customer is fully created, that is the general part, the company code part and the sales area part.
Raising the event is working great. I have put in a class in trx. SWEC together with a function module which set the class as object type if the condition is fulfilled.
Then in trx. SWED I have entered another function module to set the key for class together with object_por-catid = ‘CL’.
Then when a customer master record is created I can see in the event trace that the event is raised with the correct key.
No I want to receive the new object into my asynchronous dialog task. I define the event as terminating event – and in the code call transaction XD01.
When the work item is created I find a waiting event linkage in trx. SWE3 – of cause without key; this is unknown until after creating.
But after executing the workitem and raising the event the workitem does not receive the event and is therefore not completed.
Is this approach not possible in ABAP OO – or do I miss something in the class definition / coding?
The event is defined as public instance – I have not coded any event handler method.
Thanks,
Claus.

Hello Claus,
Interesting question, unfortunately not with a simple answer.
The issue is that you are waiting for an instance event without a key. Your object raises an event with a key => No match.
If you raise the created event without a key, you won't be able to match up two near-simultaneous creations with their corresponding work items. Same thing if you wait for a static event.
So how does SAP do it with BOR events? By breaking the rules of course!
They do some hidden trickery to bypass this problem by doing an 'Export to Memory' of the work item ID, and the CREATED event raising code bypasses the usual event linking mechanisms and looks for it's creator by retrieving the memory variable. I don't have the exact spots of code in my head, but a bit of debugging should find it.
So what can you do? Given that you have full control of the class you could do something similar and maybe also create some kind of temporary key consisting of the Work Item ID and raise an event with that, or you could maybe skip the transaction concept completely and run the create GUI entirely within your WF step - maybe a custom screen gathering the initial data and then create the object via BAPI. Time to get creative!
Hope that helps,
Mike
Edit: Or you could do the quick and dirty solution and just use the BOR events for the step and instantiate the class during the binding back to WF...

Workflow- Adding Terminating event into a Decision Step

Hi
I have a requirement like, in the decision step for example 'Approve' or 'Reject' has to be executed from the web application by triggering a terminating event for this decision step. I have copied the decision BO DECISION to ZDECISION and created two terminating events and make it ashynchrounous. But this step is not getting executed in the workflow showing error as 'no terminating event is attached to the task'.
Any input on this is welcome. If you could reply bit early as I need the information ASAP.
Thanks in advance.
Padman

Hi Padman,
Weclome to the SDN forums. We don't have a specific Workflow forum yet. Please post your questions in the General SDN Forum until we do.
I moved your questions there.
Thanks, Mark.

Link BOR Event with ABAP code (program or function)!

Hello experts,
I am trying to link program or function to bor event. Change of data in HR IT0002 trigger event CHANGE of PERSDATA Object. I need to execute some ABAP code (program or function) on CHANGE event, so I have to link event and ABAP code.
Question: is it possible and how?

Hi,
It is very much possible....
You can use the Workflow & use BO as PERSDATA & this workflow can be triggered on event change.
& You can write your code ...

Use abap class event as terminating event

Hi,
The class is say ZCL_WF_CLASS and the event END_WF.
What needs to be done to have this event used correctly as a terminating event of a workflow? Does this event require a parameter to hold the workitem id (or workflow id), as currently this event has no parameters?
Previous developer has developed the class and event and installed as a terminating event but the workflow is going into error not terminating correctly. I believe the incorrect development of the event and/or its use in the workflow is the issue. Note that nowhere is this event currently raised in any code of the workflow.
Cheers,
Ross

Hello,
Unless I'm mistaken, a terminating event for a workflow is just like any wait-for event in a workflow.
It can be based on any object or class and it can be used in various ways - to terminate a branch or terminate the workflow, for example.
The workflow listens out for the event and checks if there is a matching key. You could base it on the key of a workflow object but it makes more sense to base it on an object or class that's used in the workflow - e.g. the POSTED event of an object would be used to terminate a workflow seeking approval for the posting of an object.
It definitely won't work if the event has no parameters. I guess if you do base it on the workflow object then you would use the top-level workitem id. Try it with a test workflow and SWUE to generate the event.

INTERFACE AND EVENTS IN ABAP OO

Can some one explain me the real time need with example for use of interfaces and events in abap objects
(asking interface and events along doesnt mean that i am relating them).

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.

ABAP OO Class and Change Documents

I have created a class based on the IF_WORKFLOW interface. I created a couple of events. I created a workflow task assigned to a custom method of the class. I setup the Material Change Document to trigger the class event when there is a change. The workflow task does trigger when I change a material, but I don't know how to pass the key of the Change Document (matnr) to the workflow task/method using the ABAP OO Class interface. Any help?
Thanks,
Kenneth

Thanks for the reply Florin. Yes, I have seen Joclyn Dart's Whitepaper and blogs. They are very helpful, but I haven't seen much information within them about Change Documents. I tried your suggestions, but the material key is still not being filled when I trigger the change document and workflow task using tcode MM02.

Created an Attribute M_POR type SIBFLPOR.

me->m_por-catid = 'CL'.
me->m_por-typeid = 'ZMM_WF_MATTEC'.
me->m_por-instid = me->material.
ENDMETHOD.
Find_by_lpor with parameters LPOR and RESULT (default params) *
METHOD bi_persistent~find_by_lpor.

ECC6.0 WebDynpro(ABAP) - raising terminating event

Hi, in ECC6.0 I have a custom WDA application with a custom workflow. The workflow is launched via an event that is raised in the WDA application. However, at one point workflow sends a link to one of the WDA pages, whereby the user clicks a button which raises what should be a terminating event for the workflow task. However, while this event is raised, as confirmed in SWEL, it doesn't terminate the task. The event is raised through a WDA assistance class. The object type, event and object key are all being set properly during the raising of the event. Viewing the event in SWEL confirms the proper setting of the key fields. So why isn't the step terminating?
Thanks in advance,
Kevin

Hi,
If the object that is waiting for event has no instance, the task will not be terminated when the event is created in the system (As I said). So now the reason is clear for you.
>The event is raised through a WDA assistance class
I am not sure what you mean by this. You raise the event from the WDA assistance class? Or you raise an event for the assistance class? (Or perhaps both?).
If you raise the event for the assistance class, you should have an instance of that class in the workflow container (which you would then bind from workflow container to the task container). So, now the question is: do you have an instance of the assistance class in the WF container (when you look it from log)? Or is it initial also?
Actually I don't really even understand how you have managed to combine the WDA assistance class and WF class? How do you actually start the workflow (with which kind of event)? Whatever event it is, it should most likely instantiate some class/object in the workflow. Then in your problematic task you should most likely use this same class in the terminating event (unless there is something really fancy in your workflow).

Copy of task TS50000075 and EXTSRV - termination event not working

Hi,
We have done copy of TS50000075 and extended business object EXTSRV to ZEXTSRV
this was done to call function module ISR_CALL_FOR_CHANGE to open up adobe form in edit mode
it works well but the task is not terminated
if termination event is put just like TS50000075 like WIOBJECT, ZEXTSRV COMPLETED then workitem never ends and always stays in inbox
ZEXTSRV COMPLETED event is not triggered when the workitem is completed in the UWL
even if we trigger this event programatically , it does not find receiver and the task stays in-process
if termination event is put as _WORKITEM PROCESSED then it bahves like synchronous task ie even if the workitem is clicked and form is not completed, the workitem ends. so the user can click it only once
also i've tried following
1 - used the function module to complete the workitem in QISR BADI. but the workitem ID is not available inthe BADI. If I try to export it from business object method and import in BADI, it doesnt work
2 - find active workflows and derive workitem id and complete workitem using FM SAP_WAPI_WORKITEM_COMPLETE
     this FM doesnt work , step becomes logically deleted which is not desirable
3 - find active workflows and derive workitem id and complete workitem using other FM SAP_WAPI_SET_WORKITEM_COMPLETD
     work item is complete but there is workflow error - cannot determine succesor node
4 - find active workflows and derive workitem id and change a particular container element
    check this container element in complete workitem condition in activity step of dialog step of workflow of this task-
     workitem stays inprocess
    check this container element in parellel wait step to complete the workitem-
     parellel step executes but fork is not complete, workflow doesnt proceed
kindly help in this matter. the workitem does not get completed at all even if we force complete, workflow goes in error of - cannot determine succesor node.
is there anything specific to the EXTSRV-PROCESS method which makes the TS50000075 task to trigger EXTSRV-COMPLETED and end the workitem ?
help is much needed in this case
thank you,
b

Hi,
You need to see the event in SWEL, otherwise it will never work with workflow. Make sure that the event monitor is on (in transaction SWELS).
I cant see the event in SWEL. The vent monitor is on because if I create event in SWUE, it shows up.
How you actually create the event now?
There is BADI QISR which is always called to handle user action of PDF form. I have written the function modue to create event in the user action
>If i trigger it using funciton module -- then it doesnt find any receivere so it doesnt terminate the task. it is seen in SWEL with no receiver found. do i still need to do commit work ?
You need the COMMIT WORK always if you trigger the event in any program&function or whatever.
ok ill try doing commit work after the create event function module
Test your event with transaction SWUE. Make a test case first in a way that the task is waiting in the inbox/UWL. Then create the event in SWUE. Now, if the task gets completed, you will know that that event itself is working and your terminating event configuration is done properly. If this works, your only problem is in the event creation itself. And for that you need to tell exactly how you create the event. If you do it with your own custom code, use SAP_WAPI_CREATE_EVENT and don't forget to have COMMIT WORK after the function call.
I am doing exactly like you said. but it doesnt work ie even if I create the event in SWUE, the workitem doesnt get completed.
This event is seen in SWEL with no receivere found
I am able to infact set the workitem to complete using WAPI funciton module to complete teh task in the BADI.
but the workflow goes in to error saying , next node cannot be determined

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'.

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?
