No destination is currently free for parallel processing - SAPRCK10

Hello ABAPers,
We have scheduled SAP standard program "SAPRCK10" in background processing at our production server on daily basis.
It was worked fine on last week before but its now giving a error says "No destination is currently free for parallel processing ".
Could you please guide us how to resolve this issue ?
Thanks,

Unable to clone File Adapter receiver channel for parallel processing

Hi Experts,
I am using variable substitution for File - RFC - File with out BPM scenario(using request response, oneway bean).
While i placed the file in the sender FTP folder, the file didnt get picked up, but in communication channel monitoring, i am getting error ' Unable to clone File Adapter receiver channel for parallel processing'.
Can anybody provide me suggestions to solve this error.
Note : without variable substitution , the interface is working good.
Is it due to, i am trying the source structure field in response file adapter?

Hi,
In your CC, do you use some additional paramaters ?
like these one of point 47/48 of [Oss note 821267 - FAQ: XI 3.0 / PI 7.0/ PI 7.1 File Adapter|https://service.sap.com/sap/support/notes/821267]
Maybe there is conflict with a parallel connexion and the bean used to do asynch-synch bridge...

Java Proxy Generation not working - Support for Parallel Processing

Hi Everyone,
As per SAP Note 1230721 - Java Proxy Generation - Support for Parallel Processing, when we generate a java proxy from an interface we are supposed to get 2 archives (one for serial processing and another suffixed with "PARALLEL" for parallel processing of jaav proxies in JPR).
https://websmp230.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=1230721
We are on the correct patch level as per the Note, however when we generate java proxy from the IR for an outbound interface, it genrates only 1 zip archive (whose name we ourselves provide in the craete new archive section). This does not enable the parallel processsing of the messages in JPR.
Could you please help me in this issue, and guide as to how archives can be generated for parallel processing.
Thanks & Regards,
Rosie Sasidharan.

Hi,
Thanks a lot for your reply, Prateek.
I have already checked SAP Note 1142580 - "Java Proxy is not processing messages in parallel" where they ask to modify the ejb-jar.xml. However, on performing the change in ejb-jar.xml and while building the EAR, I get the following error:
Error! The state of the source cache is INCONSISTENT for at least one of the request DCs. The build might produce incorrect results.
Then, on going through the SAP Note 1142580 again, I realised that the SAP Note 1230721 also should be looked onto which will be needed for generating the Java proxy from Message Interfaces in IR for parallel processing.
Kindly help me if any of you have worked on such a scenario.
Thanks in advance,
Regards,
Rosie Sasidharan.

SAP job not using all dialog processes that are available for parallel processing

He Experts,
The customer is running a job which is not using all the dialog processes that are available for parallel processing. It appears to use up the parallel processes (60) for the first 4-5 minutes of the job and then maxes out about 3-5 processes for the remainder of the job.
How do I analyze the job to find out the issue from a Basis perspective?
Thanks,
Zahra

Hi Daniel,
Thanks for replying!
I don't believe its a standard job.
I was thinking of starting a trace using ST05 before the job. What do you think?
Thanks,

Troubleshooting the lockwaits for parallel processing jobs

Hi Experts,
I am facing difficulty tracing the job which is interfering with a business critical job.
The job in discussion is using parallel processing and the other jobs running at the time are also using the same.
If I see a lockwait for some process which may be a dailog process or update process spawned by these jobs, I am having difficulty knowing which one holding the lock and which one is waiting.
So, Is there any way we could identify the dailog or update processes which are used for parallel processing for a particular backgorund job.
Please help me as this is business critical and we have a high visibility in this area.
Any suggestions will be appreciated.......
Regards
Raj

Hi Raj,
First of all, please indicate if you are using SAP Business One. If yes, then you need to check those locks under SQL Management Studio.
Thanks,
Gordon

Framework for parallel processing

Hello,
Can anyone help me by giving some links or examples as to how to use the framework for parallel processing ?? (FPP)
My scenario is that I have a report that handles huge volumes of data and process it. But at present my report is not able to handle huge volume and it either dumps or hangs. So I would want to use the parallel processing framework which would then can handle huge volumes and also reduce the time for execution.
Thanks and Regards,

Thanks for the link TSharma I will try that today.
UPDATE:
I ran a non-parallel Data Pump and just let it run overnight. This time it finished after 9 hours. In this run I set the STATUS=300 parameter in the PARFILE which basically echos STATUS updates to standard out every 300 seconds (5 minutes).
And as before after 2 hours it finished 99% of the export and just spit out WAITING status for the last 7 hours until it finished. The remaining TABLES it exported (a few hundred) were all very small or ZERO rows. There clearly is something going on that is not normal. I've done this expdp before on clones of this database and it usually takes about 2-2.5 hours to finish.
The database is about 415 Gigabytes in size.
I will update what the TRACE finds and I'm also opening a case with MOS.

Regenerate Variants for parallel processing in FI-CA

Hi everybody,
does anybody know a possibility to regenerate variants for parallel processing objects (GPART for example) in FI-CA automically in a job? I can start the program RFKKDI05 with a variant but I can not tell the program to automatically regenerate the existing variants.
Any help appreciated.
Cheers,
Markus

Hello Markus,
You'll likely need to create a custom program to accomplish this task. The program may call FM FKK_DI_VARIANT_REFRESH. This will allow you to specify the object and variant which needs to be regenerated.
Best regards,
Matt

Regenerate Variants for parallel processing in PSCD

Hi everybody,
does anybody know a possibility to regenerate variants for parallel processing objects (GPART for example) in PSCD automically in a job? I can start the program RFKKDI05 with a variant but I can not tell the program to automatically regenerate the existing variants.
Any help appreciated.
Cheers,
Markus

Hi, This can be done at the time of Payment run, select the technical setting tab and then maintain variants. See to it that the intervals are all equal. Alternatively this can also be done through IMG.
IMG Menu Path: Financial Accounting > Contract Accounts Receivables and Payable> Basic Functions> Postings and Documents > Basic Settings > Maintain Documents Number Ranges.
Create a minimum of 10 num range id in this..
I hope this helps.

Best way to go for Parallel Processing?

Hi all,
I am working on a ALV report, where the user will be selecting some entries and click on process button.
Currently, the entries are processed sequentially in a loop. Now, to save time on processing, the entries have to be grouped by material number, and all the groups have to be processed in parallel.
Example:
If there are 10 items, and 2 materials, the items will be grouped into 2, and two group of items will be processed in parallel, reducing the processing time by half.
I need to know, which concept to use for the parallel processing?
Call FM in Separate Task / Call FM in Background Task or is there any other way to aceive it?
What is the maximum number of parallel/background sessions supported by SAP?
I also got some code samples:

Issue in completing the block step for parallel processing

Hi,
i have created a workflow where in i have used a block step to send workitems to multiple agents. I have used parallel processing in block step. Number of agents are determined in the runtime. Lets say i have two items in my multiple line container( two agent id). Now inside block statement i have put user decesion step. So at the same time workitems goes to the two approver for approval. When both approver take the decesion after that also command is not coming out of the block step. I want the command to be out of block step after this and goes to the next step of workflow.
Please suggest any helpful solution for it.
Regards,
Smit Shah

I think theremust be a binding problem , the binding must be some thing like the below
&USERID[&_WF_PARFOREACH_INDEX&]& ----->&_USERID_LINE&
of the block step from WF container to Block Conatiner. Because when I checked in my system it is behaving as you want., I also include one Decision step inside the block, and then hard coded the userid values int the table USERID and made the above binding and it ia working fine and in the Decision Agent I mentiond the EXPRESSION and assigned the value &_USERID_LINE&

Completing the block step for parallel processing

Hello ,
I"m using a ParForEach block   .
It works fine and 2   approves get their decision task respectively ,
I want to end all parrallel processes if one of the   approvers select the reject option .
I thought it could be done using the End condition Option .
I have defined an end condition    in the tab Parallel Procesing , the condition is an element wf_result is set to REJECT
was defined.
But   nothing resulted and althogh i check the container and the element is correctly   assigned after one of the approvers
rejects the other is still sitting there.
i ran the condiion evalate button on this step with no   success .
Please Advise

Hi Rina
In EHP4, there is the following workflows for Compensation:
04000022 ECM_SUBMIT
04000024 ECM_REJECT
04000025 ECM_CREATE
together with class CL_HRECM00_WORKFLOW_EVENT.
There, the parallel processing is used.

Parallel processing for increaing the performance

various ways of parallel processing in oracle especially using hints
Please let me knw if there exists any online documentation in understanding the concept

First of all: As a rule of thumb don't use hints. Hints make programs too unflexible. A hint may be good today, but might make things worse in future.
There are lots of documents available concerning parallel processing:
Just go to http://www.oracle.com/pls/db102/homepage?remark=tahiti and search for parallel (processing)
Due to my experience in 10g, enabling parallel processing might slow down processing extremely for regular tables. The reason are lots of waits in the coordination of the parallel processes.
If, however, you are using parallel processing for partitioned tables, parallel processing works excellent. In this case, take care to choose the partitioning criterion properly to be able to distribute processing.
If, for example, your queries / DMLs work on data corresponding to a certain time range, don't use the date field as partitioning criterion, since in this case parallel processing might work on just a single partition. Which again would result in massive waits for process coordination.
Choose another criterion to distribute the data to be accessed to at least <number of CPUs -1> partitions (one CPU is needed for the coordination process). Additionally consider to use parallel processing only in cases where large tables are involved. Compare this situation with writing a book: If you are planning to have some people writing a (technical) book consisting of just 10 pages, it wouldn't make any sense at all concerning time reduction. If, however, the book is planned to have 10 chapters, each chapter could be written by a different author. Reducing the resulting time to about 1/10 compared to a single author writing all chapters.
To enable parallel processing for a table use the following statement:
alter table <table name> parallel [<integer>];If you don't use the <integer> argument, the DB will choose the degree of parallelism, otherwise it is controlled by your <integer> value. Remember that you allways need a coordinator process, so don't choose integer to be larger than <number of CPUs minus 1>.
You can check the degree of parallelism by the degree column of user_/all_/dba_tables.
To do some timing tests, you also can force parallel dml/ddl/query for your current session.
ALTER SESSION FORCE PARALLEL DML/DDL/QUERY [<PARALLEL DEGREE>];

The parallel process for mrp.

hi exports
we plan to do the scope of planning for the total planning as a background job.
while doing that system ask for the parallal processing for mrp
what is customize step and procedure to do the parallel process for mrp.

Dear Raj,
With the help of parallel processing procedures, you can significantly improve the runtime of the total planning run.
To process in parallel, you can either select various sessions on the application server or various servers.
Parallel processing runs according to packages using the low-level code logic:
The work package, with a fixed number of materials that are internally defined in the program, is distributed over the individual servers/sessions. Once a server/session has finished processing a package, it starts processing the next package.
If a low-level code is being planned, the servers/sessions that have finished must wait until the last server/session has finished its package to avoid inconsistencies. Then the next low-level code is processed per packages.
The parallel processing procedure is switched on in the initial screen of total planning.
Activities
Define the application server with the number of sessions that can be used:
If you want to define various servers for parallel processing, enter the server with the number of sessions.
If you only want to use one server, but several sessions, enter the application server and the appropriate number of sessions.
Further notes
Parallel processing shortens the time required for calculation, however, it cannot shorten the database time as the system still only operates using one database.
The Customizing Transaction is OMIQ
