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.

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:

How to use ABAP Class to modify Web Query Result ??

Hi all !
We are using Web Templates to display our Query.
What I would like to do ( and seems a really important issue for our users! ) is to have a "PAGE BREAK" everytime the value of a charateristics change in the report
For Example :
-Page 1-
Division     Project
   A               1
                    2
                    3
-Page 2-
Division     Project
   B               1
                    2
                    3
and so on....
I read threads about using ABAP CLASS but no example what so ever...
We are presently under BW 3.1 but are considering upgrading to 7.0 by the end of the year so if there is a solution to my problem on either version i'd like to know.
If anyone has any information about how I can do this it would be most appreciated
Thx
JB.

Hi Yong,
Ravi is right, first check the blogs by Jocelyn, and if you still have specific questions you can ask them. I have used ABAP classes in workflow and I know Mike Pokraka tries to use classes exclusively.

Hide a specific cell using ABAP classes

Is there a way to hide a specific cell using ABAP classes for reports?
Marcelo

Hello Thomas Daly
    I never saw a way to grant permission to a List, the only way I ever saw a list get its permissions is thru
the group site it resides in, the Discussion Board is the problem in this case (it has preconfigure permissions but they seem more like properties that you select the value from RadioButtons). However, ms-addnew gets rid of the Add new link but it
gets rid of the one in the Discusson Board too because Discussion Board falls in the category of List.
    In other words ms-addnew in the master got rid of all of the Add new items, link etc as hoped but now
I can't add to the Discussion Board.
    I am alright with a hack (I am open to any suggestions) that would work if it works but, the List's I am referring to are all "Links" in the Quick Launch so I dont know how you would be able to apply the jquery, how would you apply the
jquery to a Links in a Quick Launch?
    Thank you

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
Ann

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.

File to Proxy Scenario using ABAP Class and DB Multi Connect

Hello Friends,
I have a scenario below and a proposed solution. I would like some input as to whether i am headed the right way.
Scenario: Thousands of records come in from the legacy accounting system. The fields of these records need to be mapped to SAP fields using cross-reference tables stored in DB2. Finally, summarize the records by deleting a few fields and feed to R/3.
Solution i proposed:
(1) File Adapter is used to send the file
(2) Although JDBC adapter comes first to mind but since i need to access the DB2 tables multiple times for each record i propose to use an ABAP class for the mapping. Within the ABAP class the intent is to open an database connection to DB2, read the relevant cross tables using native SQL and finally generate the output XML.
(3) Reciever is Proxy which feeds this generated XML to SAP for creating posting via BAPI_ACC_DOCUMENT_POST
Question: Is the above solution correct or is there a better method to implement this scenario?
Please let me know.
Thanks,
Minhaj.

Looks fine. Few observations -
1. Whether it is ABAP class or Mapping in RFC lookup, you are making multiple trips to the database.
2. It looks like PI is being used only for reading the file and converting it to XML.
3. If using PI is not mandatory, then a complete ABAP class on ECC it self would be faster than swtching between PI Java, PI ABAP then round trips to DB2 finally data push to ECC.
If you could look at something like fetching all the required RFC look up data in one go and then map the fields according, might save u on processor and network resources.

I have a requirement of calling a custom tcode from my workflow.
For this i have created a class zcl_test ( has if_workflow ) .

CALL TRANSACTION 'ZTX'. ( My tcode just has 1 input field, for testing purpose )
Then i created a task in whichi hv used this abap class and method.
But the tcode does not run when i execute the workflow.
Please help.

and the w_wi_ref is having a method GET use that method to get the values of the task container into the ABAP class.

How to auto refresh planning application -- using ABAP Class?

Hi
I have written few planning functions and attached them in one single planning sequence. One of the planning function in this sequence is de-activate data slice checkmark in planning modeler. If I execute this planning function indiviually then it works great however when I use this function in sequence then second function in row doesnot identify changes made by first function(data slice inactivate) and thus throws errors.
At the same time, if I refresh my planning session and re-execute the planning sequence then it does works as REFRESH activates the changes done by first function (de-activate data slice).
I am wondering if there is any ABAP class that can trigger this auto refresh in background else some other method to do this auto refresh ?
Please let me know if you have any thoughts on this one.
Thanks and happy holidays
Al
Edited by: Al Gon on Dec 21, 2007 3:56 AM

Hi Al,
The planning fn to deactivate was ineffective in a sequence was because the sequence which executes the functions does it on the data in the buffer and not actually on saved data, while your deactivation would work on the data after its saved.
You could perhaps run that function separately from the others in the sequence and save the data first and then perform your "deactivation" function.

I am using the ABAP class CL_BCS to send an email with a PDF attachment. The issue I have is that although I am specifying the attchment name when receiving the email the attachment is called 'MESSAGE'PDF'.
I can view the attachment in SOST and the correct attachment name appears.
I need to use this class as I am sending multiple attachments, whereas the FM only allows 1 attachment .
Has anyone had this issue before with a PDF attachment.

List of widely used ABAP classes

Hello dear forum gurus.
Im trying to find information about the classes that can handle common tasks, ie. I've found classes for ALV, for FRONTEND, etc..
I'm wondering if there is any place (similar to the java class library) where I can find all these classes, or can someone tell me wich are the most used classes (or useful).
Best regards from mexico
Edited by: Thomas Zloch on May 10, 2011 5:34 PM - subject adjusted by moderator

Still I'm looking for the classes that solve common tasks... sorry to mention java again... but like swing (for GUI) we have frontend services class ... like for string manipulation in abap we have... (I dont know... ) for ftp in ABAP we have.... or etc..
but thank you very much for the answers

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.
Jun

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,
Prabhakar Dharmala

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...
