Wait Event Step

Greetings Friends...
Im having this little trouble with this Step at my Workflow (WS9000000004).
In my Workflow Template I got step "Wait Event" for BUS2105 (ZBUS2105) to Event "ZPROCESSED".
At some BADI for ME41, I'm using FM SWE_CREATE_EVENT for BUS2105, Event "ZPROCESSED".
(Using "BUS2105" as object, "ZPROCESSED" as Event and "EBELN" (quotation nº) as Object-Key)
At Swel, when someone creates (saves) a new Quotation, it shows that this Event is triggered properly.
(But doesnt have any receiver, but I think this is correct, as I'm not using this event to Start a Workflow)
But all my flows from WS90000000004, (that is still processing) are stuck waiting, for event ZPROCESSED.
Am I missing something?
Att,
José Junior
PS: "ZPROCESSED" isnt the starting event from WS900000004. It is just a Step Event. The Starting event is "ZCREATE' who is working properly when a new Purchase Requisition is created. (Again, using SWE_CREATE_EVENT at some Exit in ME51N).

What is the option that you have used to wait I mean
Wait for event
Wait for Local Event
Wait for Condition etc.
Wait for Event
can you please let us know.
If you have used wait for condition check whether the conditon is satisfied or not
Yes... I mean. I am waiting the event to get the new Quotation Number Created.
So I can check if the Quotation have itens of the particular Purchase Requisition.
If yes, check the PR status, if all itens were "quotated", Status receives S. Then exits Loop.
Or by "Condition Check" you mean another thing, like somekind of the Step configuration itself?
If you are using wait for event trigger the event by using EVENT CREATOR step
Nope.... This Event is getting (actually should have been) triggered by SWE_EVENT_CREATOR at
BADI in ME41. This FM is working properly, as I can see him at SWEL. (ZPROCESSED for BUS2105
after Request for Quotation is created.)

Workflow error in fork step, process control, wait event

I am using fork step in workflow which has 2 parallel branches. In 1st branch i have a user decision step followed by a task for posting PO document in case of approval. In the 2nd branch of fork step I have a wait step to wait for an event followed by the same task for posting document with a process control step after that in the end to cancel the workitem(workitem generated by user decision step in the 1st branch of fork). I created the event by using a custom BOR object.
After the fork step is triggered, i have both a wait event running and workitem generated. When i raise the wait event from SWUE by entering the event, object key etc it works fine i.e., the workitem in the other branch is set of logically deleted and workflow ends.
But if the wait event is triggered from the program i.e., using FM SWW_WI_CREATE_VIA_EVENT, both get an error message in workflow log(SWIA). The message is: Error when executing the binding between work item 000000XXXXXX and flow item 000000XXXXXX where workitem number is the workitem id of the posting document task and flow item id is the workflow parent id

hi,
message is self explanatory.
Activate the event trace SWELS, then do the event with SWUE and within your program (als please use SAP_WAPI function modules).
Now compare the 2 events in SWEL to see what the differences are .
Kind regards, Rob Dielemans

Help creating a Wait for event step

Friends,
I'm working in the following way:
1-My workflow to create a vendor is triggered.
2-Fork with 2 flows (1 to terminate):
2.1- if user executed XK01 by wi and created the vendor;
OR
2.2- if the user executed xk01 directly and created the vendor, by exit, I call an event... that is in a Wait for step task. But it is not working. in swel it is givin me the message: 'Linkage deactivated'.
please help me!

Steady on there Amandeep...
1. Don't change the error feedback settings on the event linkage directly. Leave it on "system setting".
2. Go to transaction SWEQADM and select the "Basic Data" tab.
3. On the basic data tab set the "behaviour on error feedback" to:
a) "Mark linkage as having errors" - if this is a QAS or PROD system - that will let you redeliver the event from SWEQADM once you have fixed the problem.
b) ""Do not change linkage" - BUT ONLY!!!!!!!!! if this is a development system where no-one cares where dead workflow instances go. And usually I would recommend making the development system "Mark linkage as having errors" too - gets you used to the event problem diagnosis/redelivery process for when you get to QAS/PRD.
The most common problems I see for deactivated event linkages is workflow definition not activated, or mandatory import container elements not provided in the workflow/event binding.

Error in "Wait for event" step

Hi,
I try to use a wait for an event (CREATED) on a delegated subtype to business object KNB1.
Container element in the wait step is empty at the time of creation of the runtime wait item but I know what the key of the container element has to be so my idea was to set in a check funktion module in trx. SWEINST and filter out irrelevant events.
But when the waitstep is to be created, the workflow goes into error: WL 442 No valid object for the container element.
Should this not be possible?
Any suggestions for another solution?
I have also tried to instantiate the object before the wait for event step - but since the object does not exist in the database yet - method GENERIC.INSTANTIATE goes in error, too.
WAS 700 sp 11 with ERP 6.0 but also tried on a 620 with 4.7
Thanks,
Regards,
Claus Lücking

Hi Mark,
Yes, you are right - I am waiting for an event on a object not yet created:
I am waiting for a customer to be created in FI via change documents (table KNB1). Since the customer is going to be created in a company code that has a one-to-one reference to the sales organization where it is created first, I know the key of FI customer to be created.
Example: A Customer 23 is created in sales area 1000-01-01 and the workflow is triggered via an event KNVV.CREATED. Then I would like to wait for event KNB1.CREATED for customer 23 in company code 1000.
Thanks,
Claus.

Workflow WAIT FOR EVENT STEP deadline not working

Hi,
Need some inputs for the experienced people;
I have a wait for event step in a workflow with deadline monitoring (Latest End) but it doesn't seem to work.
Ofcourse, all the required setting are in place and deadline works fine for other Activity steps.
The problem is specific to Wait for event step.
The alternative is having a fork but I just want to know why the wait step with deadline doesn't work.
Thanks,
Roopesh

Hello Ajay,
Can you share with us what did you do to solve your problem?
I'm facing the same thing in my project now, I'm wandering if you could help me with this one.
I have this wait for an event step wich is configured to wait 4 minutes since the work item creation. I've also selected 'Modeled' on the Action field, and a display text for the outcome.
But in one of my tests, the event hasn't occurred and the workflow stuck in this task forever.
Thanks in advance.
Regards.
Actually, I think I got this handled. This thread was really helpful to me: http://scn.sap.com/thread/47482

however if i execute the FM SAP_WAPI_CREATE_EVENT by passing the values it works fine.
Thanks
Saurabh

Hi
however if i execute the
FM SAP_WAPI_CREATE_EVENT by passing
the values it works fine.
It will trigger only when you execute the above function module or
SWE_EVENT_CREATE because
You have a BO and an event associated with it now when you want to trigger this this event through program then you have to make a kind of mapping between BO and your program so thta's what this Fm does, when ever you execute the program as you are passing all the values to the Function the Evnt associated with the BO is triggered.
In order to trigger use SWE_EVENT_CREATE aand after calling this fucntion use COMMIT WORK statement
Could you let me know what condidtion did you write for the WAIT step to continue.

Wait for event step without callback

Hi All,
In 4.6C I have the following problem:
We have a workflow that has a fork with 2 branches, with 1 necessary for continuing the fork.
One of the branches has a dynamic parallel processing step on a multiline container element, where each parallel process is a wait for event step. For example if the multiline element has 5 records, than there will be 5 parallel wait for event steps on this branch, and if all 5 are completed, then the workflow continues after the fork and the other branch should be logically deleted (normal behaviour).
The other branch has a single wait for event step, if this event is received, the other branch's parallel wait for event steps should be deleted to continue.
The problem is that when the event for the latter single wait step is received, the step gets completed, but sometimes the parallel wait for event steps on the other branch are not deleted and the wokflow does not continue. The completed wait for event step shows that the callback is not completed yet.
I tried to fix these steps in SWPC, but in 4.6C it does not work for wait for event steps w/o callback. There's an OSS note for higher releases where this is fixed to enable SWPC for wait for events, so I copied it to a custom program and use that right now.
First question is why does the system not continue these workflow's when the event is received? My guess is that the tRFC calls get stuck and when the tRFC job reprocesses the entries, it does not do it correctly. For example lately we had a tablespace problem that caused some tRFC calls to go into error. The waiting steps in the instances were completed w/o callback. I reprocessed the tRFC entries, which created new entries in the Workflow logs showing that the events are received, but the workflows still hang.
Second question, it takes a lot of time to logically delete those parallel wait for event steps. When the event for the single wait for event is received and the workflow continues w/o problem, it may take tens of minutes from the receipt of the event until the parallel wait for event steps get deleted and the WF continues. Why does it take so long?
Thanks,
KK

Hi,
Regarding the delay and the hundreds of thousand SWW_CONT updates... the main workflow on one branch does a dynamic parallel processing of a subworkflow using a multiline container element that can have 50 or even 100 elements. So we can have 50 or even 100 subworkflows waiting for their event to be triggered.
The main workflow container contains many elements, some multiline with long structures, so in one instance the main flow had 8000 entries in SWW_CONT (each field of a structure is a separate record in SWW_CONT).
Now if I do the math, when this workflow loads all the container elements of the main flow into the 100 waiting subflows before deleting them and continuing along the other branch, it creates 100 times 8000 entries in SWW_CONT, that is 800.000 inserts!
And this was ONE single workflow.. Imagine when we have just a few hundred and they all want to continue at the same time...
Anyway, the beauty comes now....
I created a simple main flow with a single multiline import parameter USERS of object USER. It has a fork with 2 branches, 1 enough to continue. One branch is a user decision with 1 option: Continue. The other branch has a subworkflow and it does dynamic parallel processing with the multiline element USERS.
The subworkflow has one single import element USER of object USER. It has only one step, a wait for event, waiting for the DELETED event of the USER object.
That's the scenario.
When I start the main flow, filling the USERS parameter with two user objects, on the first branch it starts the two parallel waiting subflows with one user each, and I get the decision step on the other branch. If I check the subflow containers this time, they only have one USER object each.
Now if I complete the user decision, the workflow continues, logically deletes the subflows and completes. If I check the subflow containers after this, they all include the USERS multile container element with all the USERS I started the main flow with!
So this time it was a different main flow, different subflow, different events. I guess there can't be any custom code doing this, unless there's some generic workflow user exit somewhere.
Feel free to test this yourselves if you have 4.6C, quite easy scenario. Guess I'll try in ECC 6.0 too just to see...
And I'll report to SAP for sure.

Wait for Event Step (Urgent).

Hi, all!
I m unable to successfully execute my WAIT FOR EVENT step in my Workflow.
Scenario:
Have my own customised screen for HR approval process. In the second step after displaying to the approver when he actually presses on the APPROVE button my APPROVED event for the same object is triggered. Now I m waiting for this event im my workflow. Done the WAIT FOR EVENT in the WF .ie. from WF container selected the BOR and assigned the APPROVED event in the WAIT FOR EVENT step.
Problem:
My WF is unable to catch the event .ie. even in SWEL, "NO RECEIVER FOUND".
Thanks and Regards,
Sudipto

Hi!
Thanks.
Actually I m facing a peculiar porblem...
Scenario: My WF has 3 steps.
1)The user fills in the initial screen.
2)Then it goes to the second person who adds comments and approves it.
3)This triggers the APPROVE event for the same OBJECT.
For which my WF has the WAIT FOR EVENT. After which there is just this SEND MAIL task
Problem:
My WF when executed by itself actually performs perfectly and the SEND MAIL is actually executed.
But when it is initiated from my ABAP prog...It goes to the next level user in line, where he adds his comments n then it goes to my WAIT FOR EVENT but my SEND MAIL is not executed.
As the 2nd step of display is done with the object key hence there shud not be any value passing prob from my prog.
I cannot understand the prob.....

Sudipto

Wait for Event step in Workflow (Urgent).

Hi,all!
I am unable to implement the wait for event successfully in my workflow..
Sceanrio: I have created a container element in the WF with of type a BOR(ISUPARTNER) whose CREATED event is being waited for in the workflow.
Then in the WAIT FOR EVENT step in WF I m giving putting in the details of the event..
Then putting a send mail after this.
Problem: Now my workflow is throwing error and the send mail task is not executed even after the said event is done in the system..
Plz... suggest as to how to do it..
Thanks,
Sudipto

Now for this I m actually creating a container element of type BOR B in my workflow n putting a step WAIT FOR EVENT in which I m putting the CREATED event. For triggering the CREATED event no instance is required...
- Once again, Wait For Event step is only possible when the Object Key is available to the Workflow container when the flow reaches the event (are you waiting for a specific ISUPARTNER to be created or you don't care as long as some ISUPARTNER is created).
my event CREATED is not getting triggered automatically...
- First check if the standard system triggers the event for your object. If not explore different options for doing that.
For your scenario, check if you can trigger a custom event BORB_Created for BORA when BORB is created and use BORA in the Wait step.
Please post future Workflow questions in the Business Process Management forum.
Cheers,
Ramki Maley.

Error while completing Wait for event step

Hi Gurus,
I have a Workflow developed which has a "Wait for Event" step.
In that step,I am facing a problem .It seems the step is not getting completed properly.
When I check in SWEL it shows the Event is triggered.But the next which is a 'Send Mail' step is not getting executed.
The Event shows action status as "Receiver started correctly".
When i executed "Complete Manually " in SWIA,it executed correctly and also the further steps got executed.
What could be the issue ?
Many Thanks in advance !
Regards,
Ameya Kulkarni

Hello Ameya !
                 To one of my replies to this thread you have stated that no container elements are configured to wait for event step.
                 Without business object,event and container element with object reference, wait for event will not fire.
                 When the user changes the status in KO02, event fires and is seen in SWEL.But, if it should reflect in workflow, afore- mentioned details needs to be configured in wait for event step.
                Have you configured this wait for event step with event 2 ?

How to use wait for event step

Hi,
I need to trigger wait for event step for my workflow but I am not able to trigger that .
Can anyany one of you tell me in detail what are the necessary config.and bindings i need to do for that .
Also i need to pass data from my report program(where i am triggering the event for the wait activity) to the workflow through event triggering for the wait step.
Please tell me how can I do that .
Thanks in advance.
Anand

Hi,
I think you can use the function module "SAP_WAPI_CREATE_EVENT" to trigger an event. Make sure that the instance data is same in both ends. To send data from your report, you can populate the event container using the container related macros.

Library Cache Pin Wait Event (within the context of APEX)

Hello,
Firstly -
Oracle Version: 10.2.0.4.0
Apex Version: 3.0.1.00.08
Okay, my colleague (no really! This isn't one of those "Ahem ... A friend of mine has contracted something nasty +downstairs+..."-type questions) is having problems compiling a package (using TOAD incidentally, but it's the same in SQL Developer).
I've searched the forum and the web for a bit of help on what's maybe happening here and it appears to be related to a concurrency conflict with the package definition - from what I can understand it's a case of the package is in use by another session, therefore another session cannot alter it at the same time (which makes sense)
"What does this have to do with APEX?"... well, he is working on this package using the following methodology:
1. Compile the package body/spec (as necessary - body more often obviously)
2. run an apex page which uses the code in a process, which may or may not result in the error page being displayed
3. Making changes to the package body/spec
repeat steps 1-3 ad nauseum...
He is the only user directly accessing the schema (and the only user accessing the page via APEX too, although I appreciate this isn't quite the same thing).
I was wondering if, due to the architecture of APEX (the use of session pools etc), the state of a package might be being retained in some manner, thus resulting in this library cache pin wait event? If so, is there anything I can do to mitigate against this occurring?
p.s. the only difference I can see between this particular package and any other package in the schema is that this one interacts with blobs (including making references to the wwv_flow_files view) - with blobs being passed as parameters between procedures (thus potentially creating temporary blobs which may or may not being closed).
Any ideas?
p.p.s. there are also no DBMS_SCHEDULER jobs or anything that might potentially be running the code incidentally...

Wait Time / Timeout Time in waiting events

Hi,
From manual, I came to know that some of waiting events having wait time or time out duration. I have not understood, what happens if it has reached timeout. What happens next ? ( Will you explain in more detail ). It saysl it will renew wait event. ( I have not understood what does mean "RENEW", Or what steps will be taken by Oracle, what happens if again reached timeout ) ?
Thanks for clearing my doubt in detail.

Wait Events "log file parallel write" / "log file sync" during CREATE INDEX

Hello guys,
at my current project i am performing some performance tests for oracle data guard. The question is "How does a LGWR SYNC transfer influences the system performance?"
To get some performance values, that i can compare i just built up a normal oracle database in the first step.
Now i am performing different tests like creating "large" indexes, massive parallel inserts/commits, etc. to get the bench mark.
My database is an oracle 10.2.0.4 with multiplexed redo log files on AIX.
I am creating an index on a "normal" table .. i execute "dbms_workload_repository.create_snapshot()" before and after the CREATE INDEX to get an equivalent timeframe for the AWR report.
After the index is built up (round about 9 GB) i perform an awrrpt.sql to get the AWR report.
And now take a look at these values from the AWR
 Avg
 %Time Total Wait wait Waits
Event Waits -outs Time (s) (ms) /txn
log file parallel write 10,019 .0 132 13 33.5
log file sync 293 .7 4 15 1.0
......How can this be possible?
Regarding to the documentation
-> log file sync: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3120
Wait Time: The wait time includes the writing of the log buffer and the post.-> log file parallel write: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/waitevents003.htm#sthref3104
Wait Time: Time it takes for the I/Os to complete. Even though redo records are written in parallel, the parallel write is not complete until the last I/O is on disk.This was also my understanding .. the "log file sync" wait time should be higher than the "log file parallel write" wait time, because of it includes the I/O and the response time to the user session.
I could accept it, if the values are close to each other (maybe round about 1 second in total) .. but the different between 132 seconds and 4 seconds is too noticeable.
Is the behavior of the log file sync/write different when performing a DDL like CREATE INDEX (maybe async .. like you can influence it with the initialization parameter COMMIT_WRITE??)?
Do you have any idea how these values come about?
Any thoughts/ideas are welcome.
Thanks and Regards

Thank you for Nice Idea.
In this case, How can we reduce "log file parallel write" and "log file sync" waited time?
CREATE INDEX with NOLOGGINGA NOLOGGING can help, can't it?Yes - if you create index nologging then you wouldn't be generating that 10GB of redo log, so the waits would disappear.
Two points on nologging, though:
<ul>
it's "only" an index, so you could always rebuild it in the event of media corruption, but if you had lots of indexes created nologging this might cause an unreasonable delay before the system was usable again - so you should decide on a fallback option, such as taking a new backup of the tablespace as soon as all the nologging operatons had completed.
If the database, or that tablespace, is in +"force logging"+ mode, the nologging will not work.
</ul>
Don't get too alarmed by the waits, though. My guess is that the +"log file sync"+ waits are mostly from other sessions, and since there aren't many of them the other sessions are probably not seeing a performance issue. The +"log file parallel write"+ waits are caused by your create index, but they are happeninng to lgwr in the background which is running concurrently with your session - so your session is not (directly) affected by them, so may not be seeing a performance issue.
The other sessions are seeing relatively high sync times because their log file syncs have to wait for one of the large writes that you have triggered to complete, and then the logwriter includes their (little) writes with your next (large) write.
There may be a performance impact, though, from the pure volume of I/O. Apart from the I/O to write the index you have LGWR writting (N copies) of the redo for the index and ARCH is reading and writing the completed log files caused by the index build. So the 9GB of index could easily be responsible for vastly more I/O than the initial 9GB.

Find the Wait events for an objects.

Hi Gurus.
I need you help to find out the wait events for a particular table and index when batch export job running from the application. I have done some work around to to find out, but i am not able to figure out the issue or what are the wait events. i am working on linux 4node rac 11gR2.
Below are the steps i have done.
1. find object_id for a table finding the wait events to that object_id.
SYS@ccmintpt1 SQL>select data_object_id from dba_objects where object_name='ACCOUNT_DETAIL_DENORM';
DATA_OBJECT_ID
82646
88518
84184
SYS@ccmintpt1 SQL>select w.sid,w.event,w.wait_class,w.wait_class# from gv$session s,gv$session_wait w where s.row_wait_obj#=82646;
no rows selected
SYS@ccmintpt1 SQL>select w.sid,w.event,w.wait_class,w.wait_class# from gv$session s,gv$session_wait w where s.row_wait_obj#=88518;
no rows selected
SYS@ccmintpt1 SQL>select w.sid,w.event,w.wait_class,w.wait_class# from gv$session s,gv$session_wait w where s.row_wait_obj#=84184;
no rows selected
2. find the object id for the index of that table and finding the wait events to that object_id.
SYS@ccmintpt1 SQL>select data_object_id from dba_objects where object_name='XAK2ACCOUNT_DETAIL_DENORM';
DATA_OBJECT_ID

From this output, what are the waits events i need to take into consideration.
Is this the right approach to follow?
Please let me know.
Thanks in advance.
