Wait step stops during PI BPM workflow

Hello Guys,
I'm testing the one BPM scenario in my test system, during runtime the workflow stops before wait step (only 1 min) but after 1 min the message not process and it is stucked in 'in process' state.
Earlier the scenario works good with wait step, but now it's not working in Dev & test systems but only working in Production system,
Note: Recently we migrated from Service pack upgraded from PI 7.31 SP06 to SP11 in all three systems.
Do you have any idea on this error? could you please suggest me
Thank you.

Hello Udo,
You are absolutely right, I reschedule my background jobs in t.code SXMB_ADM_BPE then it resolved my issue.
And I have one more question currently my PI systems are in 7.31 SP11 and getting error ' Cache content Obsolete' (SXI_CACHE-->deltaMonitoring)
Could you please provide me any suggestions on this .
Thank you.

WAIT STEP issue in a BPM

Hi all,
We have a following message (as a result of a transformation) FECHA is an xsd:date and HORA is an xsd:time. The cardinality of every elements is 1..1:
<?xml version="1.0" encoding="UTF-8" ?> <MT_Retraso_Entrada_Wait>
<row>
<FECHA>2006-10-27</FECHA>
<HORA>15:00:00.0</HORA>
</row>
</MT_Retraso_Entrada_Wait>
And we assing this values to the wait step but it doesn't work.
Has anybody any idea?
Thanks

HI SUDHEER,
Many thnaks for your help, But it is working with this value as constant.
I tried to remove the 0 but still not working is not picking up this values, the desired date and time in the wait step are empty.
How are you using the same MT just in case?.
Many thanks for your help.

Wait Step in Workflow

Hi Workflow gurus,
I have 2 questions want to ask.
1. We have a wait step deadline monitoring in our workflow project. Let's say 30 day wait period. After 30 days workflow is getting triggered & everything works fine. But that is really required in Production. In Dev/QA systems we do not want to wait really 30 day. We want a small time period, let's say 1 day. Now what is the best way to handle this? Meaning Different time periods for different systems for the same workflow & same wait step period.
2. If a work item is waiting for a wait step to be completed(for ex waiting for 60 day wait period) before 60 day itself,
can we execute manually that work item using any std report?
Kindly help me.
Thanks,
Pandu.

Hi Pandu,
1. There are a couple of things you can do in this instance. You could manually remove the deadline after the 1 day threshold.
Open the work item and select Edit -> Change -> Change Deadline -> Excute and then remove the Requested Start deadline
(ensure you have Technical View set for the work item display)
Deadline monitoring (SWWDHEX) will have to execute before the work item will transition out of a Waiting state.
Alternatively you could store the deadline parameter externally in a config table somewhere and retrieve it into the workflow for use with your deadline. Obviously when you change the configuration from 30 days to 1 taking care to ensure that the changes are not transported to prod. Not really fond of this since there is a risk of transporting the changes.
2. Transactions like SWIA don't allow you to execute work items in a Waiting state. So as above go into the work item and either change the deadline or execute.
I hope this helps,
Best Regards,
Trevor

Wait step event

Hi,
i am new to the workflows.i worked in support project and i am looking for development.
could any one can explain:
what is wait step event,
when it should be used and
while creating the wait step event do we use any tcodes to assign the events(swetypv,sweinst etc)
generally when we use starting events we will write start conditions based up on that event will be triggered so in the same way how waitstep event will be triggered?
Regards,
Mudhiraj

Use
A wait step can wait for:
u2022 An event
u2022A condition
u2022A local event
u2022An event that is initially received by the workflow.
At runtime, a wait step is represented by a wait step work item. Wait step work items are not displayed in the Business Workplace. You can, however, locate these using work item selection.
Correlations
You can use a correlation when waiting for an event and when waiting for an event by using workflow.
A correlation enables you to identify objects that belong together, for example, a quotation and the relevant sales order.
Features
Wait for Event
When waiting for an event, the wait step is terminated when the event specifies occurs. This event
terminates all wait steps waiting for this event.
You can use this type of wait step for the following purposes:
u2022To suspend the workflow until a defined event has occurred.
A workflow is to wait until documents requested have been provided for an applicant activity. Once the
requested documents are received, the transaction used for inbound processing and archiving creates an
event which the wait step waits as a receiver.
u2022To wait for an event in a parallel processing branch, which renders processing in the other
branches unnecessary.
The event for which the wait step waits should not be created in the other branches of the fork.
u2022Wait for the result or a message from another workflow that was started in another system by the
WebFlow function.
u2022Wait for a message of the process that the workflow started using a Wf-XML message.
Wait for Condition
When waiting for an event, the wait step is terminated when the corresponding condition returns the
value true.
Wait for Local Event
When waiting for a local event, the wait step is terminated when this event occurs.
Wait for Event Via Workflow
When waiting for an event via the workflow, the event is initially received and temporarily saved by
the workflow. Once the wait step has been activated, the event is forwarded to the wait step. During
waiting via the workflow, the event can terminate a maximum of one wait step. If several wait steps are
active, the event terminates the oldest wait step.

ERROR in the wait step

Hi all,
I have a requirement, where automatic payment proposal goes for an approval process. When the proposal has created in the tcode F110 based upon user who has loged in a push button "Trigger Workflow" will appear once proposal is made (enchansment), When the user press this button workflow will be triggered using the function module. After that i am finding the approver details. After this step type, i am checking for the condition (payment or proposal) if it is proposal flow will proceed futher. After this i have used a fork step - two branches 1. for the workflow proceed further 2. cancle the workflow when and event "ZSAVE_ON_CLICK" (custome defined event) is triggered.
I am getting the error at this wait step. The error is ""Workflow 000000703573 wait step 0000000248: No valid object ID in container element 'ZbusF110'""
Thing i have done.
1. I check the binding, here i am passing two key values of the bo to my workflow container from the event container.
2. When i tried to bind the EVTOBJECT to zbusf110 - it is giving me an warining "'_EVT_OBJECT' is not an export element and hence sometimes has no defined value"
Kindly help me in solving this issue.
Thanks and Regards

Wait step in BPM stops the process permanently

Hi all.
I have a BPM with a Wait Step inside. When the process reaches the wait step the process gets locked permanently.
I execute TCODE SM12, remove the lock for the process and the process finishes without errors.
Why does the BPM hangs with the wait step? Could anybody help me with this issue.
Thanks a lot,
Gari.

Hi Gökhan.
I'm using SP12. The Self-test about BPE in RWB reports error for "Schedule Background Job for Packaging" and "Schedule Background Job for Reorganization". Details for the error say "Background job for packaging is not required".
Thanks,

BPM wait step : RWB"To Be Delivered status": SXMB_MONI"Message being sent"

Hi All,
I have a BPM interface running fine since 1 year.
In this BPM I have wait step for 5 minutes.
But yesterday message is stopped on wait and not proceeding ahead.
I checked XML is good as per mapping. and in runtime wirk bench message is still in "To Be Delivered status"
and in SXMB_MONI message column Outbound Status still showing "Message being sent" even after 12 hours.(wait is only 5 minutes). And below is the trace of last message.
Please guide how to handle or restart this message. in SMQ1 & SMQ2 there are no queues showing:

BPM(with wait step) calling another BPM

Hello,
I have this scenario whereby i need to call a BPM from another BPM process. Call it BPM1 and BPM2. BPM1 will have a Sync-Send-step to call BPM2.
The following is what i have setup:-
Working OKAY:-
BPM1 (receive from file, send syn step to BPM2) --> BPM2(receive step (Open S/A Brige) from BPM1, send step (Close S/A Bridge))
But if i put an wait step (for 1 minute, see below) before the send syn step in BPM1, i will have problem and the queue in BPM1 show "STOP" and the BPM2 queue show "RETRY".
Problem:-
BPM1 (receive from file, wait step, send syn step to BPM2) --> BPM2(receive step (Open S/A Brige) from BPM1, send step (Close S/A Bridge))
Yes, the RETRY will work but the problem is, my BPM1 has already timeout and has ERROR (see from SWWL) and BPM2 has exceptional error in the Close A/S Bridge send step (because it can't send back to BPM1).
Anyone has any idea how to resolve this? and hopefully the above is clear enough to discribe the problem that i'm facing now.
Any suggestions are welcome, scott.

The minimum BPM-wait duration is 1 min and cannot be decreased below that....

ABAP OO class-based workflow, wait step

Hello,
I'm hoping someone is able to help me. I've implemented a class which triggers a custom workflow through a custom event of the class. At one point during the workflow I want to use a wait step that waits for another custom event to occur. I've created my second event which I want to trigger from an ABAP ALV Grid report for users, that will allow them to select the specific workflows to trigger this event for. My problem is, I am having trouble figuring out how to find the correct object instance of my class from within the ABAP program and trigger the event specifically for that instance, so that the workflow can continue and eventually complete. I have implemented the IF_WORKFLOW interface and up to this point the workflow is functioning correctly.
Thanks,
Leslie

Hello,
Sorry, not sure where my brain was. Actually I do know: at two clients with projects going live this month, so apologies for a rushed and inaccurate response. It's CL_SWF_EVT_EVENT.
Jocelyn's blog I referred to includes a code sample using the same class on how to raise an event with an object key.
Regarding your second question: No you don't need to do any binding. Just use an instance of your object and it will wait for an event with the same key. The WF part is very straightforward and works exactly like BOR, it's just raising event that can't be done with the WAPI.
Cheers,
Mike

Wait step in BPM hangs!

Hello,
I am using a wait step in a BPM. Type is "Wait specified time period". The period is 2 minutes.
I can see from process monitoring that my BPM reaches the above step. And then it just hangs !!!!
Time goes by but nothing happens. The BPM never! goes to the next step.
I cannot understand it. Such a simple step is causing me great pain!!!!
Anynone outhere with similar experience ???
Thanks in advance
Dimitris Hagigeorgiou

Hi,
I know this question is inactive, but I had the same problem, and the proposed solution isn't correct. The problem came after upgrading to SP17- What had changed?
Anyways, I checked the workflow customizing (trx swf_xi_customizing) and all were checked, green and good. Finally, after lots of testing and reactivating for no good, I tried executing the checked "Schedule Background Job for Missed Deadlines" function in the workflow customizing again, and behold: the scheduled job had been rescheduled after the upgrade to start 6 months into the future!? Why? No idea, but after re-scheduling, all wait step are executed nicely.
Hope this will be helpful to some other frustrated BPM administrator someday. Regards,
Emil

XI BPM Wait Step

We are attempting to receive an IDoc into BPM and look at the begin date of a record (BEGDA) and based on the date in BEGDA send the record immediately (if system date <= today) or hold the record if BEGDA > system date.
We have constructed an abstract interface for the IDoc and a Wait Until Specified Time, then send the message.
The BPM does not send the message at all.
The container field for BEGDA in BPM is populated with a string (20050524) in workflow monitoring.
There is no documentation we can find on what this BPM process is looking for i.e. will the xsd string inherent with IDoc's work in this BPM or do we need to transform the field into a date?
Any help would be greatly appreciated.

Hi David,
I assume that field BEGDA is from the IDOC:
- in the Wait Step - when you click on the Date property
en Expression editor opens
- then you choose your BEGDA field right?
but
below you see your Xpath Expression to this field and the "Type" is is set to xsd:Date? or String?
if string try changing it to date because even if the BEGDA has Date type in the IDOC when you choose it in the Expression editor it becomes string but you can change it over there
Have you checked it?

michal

SAP MDM Workflow: Wait Step

Dear Experts,
We have a scenario to send an email for the created/changed records periodically/daily, but a single mail should be sent for all the records to the users.
And we think that we can make use of the Wait Step for this activity, but we are not getting the values for GM Time Field and Literal Time Field.
Thanks And Regards
Gaurav Kumar Sharma

Hi Gaurav,
You can also try this scenario:
1.Create two ports one for outbound and other for inbound.
2. Create a sydnication map which will trigger automatically at a specific time using MDSS which only synidcates the records which were created/updated on that day..... say material number
3. Use PI to pick the syndicated file and drop it in a inbound port which was created earlier.
4. Create a import map for importing the syndicated file use MDIS here, with a workflow for notification under configuration options.
5. Workflow design will be start (Check out)->Notification->Stop (Roll back) which triggers on Record import.
The above steps will help you to send notification of created and updated records in one mail using MDM.
Let me know if you have any questions.
regards
Sowseel

File BPM Webservice IDOC .........Error in BPM workflow(Sync send step)

Hi all,
I have the same type scenario that is file initiates the bpm that invokes the Webservice.the file data goes into bpm as the input data of the webservice and webservice gives the response and then the web-service response is mapped to
idoc and finally posted to R/3.
The interface sI created:
1.outbound Async -
>for file
2. Abstract async----
>bpm reciever step.
3.Abstract sync----
>bpm sync send step.
4.inbound sync -
>for the webservice to recieve the reqst and to send the response to Abstract sync
5.Abstract async----
>to send the data out of BPM
6.inbound async----
for idoc
created 3 communication channel.
1.file adapter: sender
2.SOAP adapter: Recv
3.IDOC adapter: Recv
created 3 reciever determination
Business process instance in ID
reciever agreement(2)
interface determaination
But getting a problem in BPM.
I think the scenario is logically correct as I have seen previous
SDN suggestions.
But getting the problem in BPM's sync step.and the SOAP rec channel is also inactive.in BPM workflow I can see the recv step is getting file req data but after that in the sync send step
its stuck up.getting error.
Please sir suggest me.

Remove the interface you created for Idoc that is inbound async one. use the imported Idoc itself as the interface and also as the message type. Everything else looks good though i did not really evaluate ur ID configuration..

BPM Wait step!

Friends,
I have BPM which has the FOR-EACH Block in it. After the first message processed I have to wait for atleast 5 seconds to process the next message in FOR-EACH Block. The default BPM wait step has minimum of 1 Minute. Is there any other way we can make to wait for x seconds?
Please let me know!
Thanks,
raj.

Wait step in BPM

Hi All,
The minimum BPM-wait duration is 1 min and cannot be decreased below that....can we use 0.5 for 1/2 min.
or can any one suggest what would be alternate option to achieve 2 to 3 min delay.
One solution is to write a mapping and use udf to delay for one 2 to 3 seconds.Apart from this any other better solution
Please suggest
Regards,
Vidya

Introducing a delay of les than a minute is not possible in the BPM (using a Wait step)
The other method (using UDF in mapping....sleep.Thread) should work and does not seem to induce any performance issue.
or can any one suggest what would be alternate option to achieve 2 to 3 *min* delay.
The Wait step itself should be useful for this requirement.
For having the delay in seconds use the UDF.
Regards,
Abhishek.
