msg of yester days chain ........
Errors have been reported in Business Information Warehouse during IDoc update:
Could not find code page for receiving system
error msg in bd87 (with idoc status 02 )
tried to process idoc manually but it didnt happen ...throughing same error....
one more thing here is same process chain status on 16th is in yellow status .....
its in yellow status at dtp load step ....on right click on dtp_load variant --->in batch montior --->job overview
dtp_laod job was is ready status ....
i thought this status effecting others so tried to schedule the job couldnt ....
so deleted job in confession....
now and process which is bfr dtp_load is in yellow and whole chain is in yellow ....
what shall i do now ??how to correct this ??

or shall retrive deleted job wit basis ppl help???
please help me...
whoever helps me to fix this issue will rewarded wit full points and i will be greatful to them ...
Regars, \
Harry...

Yes, as rightly said you need to run the previous delta before updating new records in the latest request. If possible de-schedule the chains for a while, delete the old deltas (assuming you are using flexible updates?) and try to repeat the loads manually & proceed to activate & schedule once the delta has finished processing. If you still think this is an issue related to idocs processing, you can do the re-processing, provided they do not create fresh batch of idocs in the source system. You can re-process the idocs both inbound & out bound using reports like RBDAGAIN (But again, use extreme caution on these!). Please refer the #scn wiki on http://goo.gl/njVLS for more information on the idocs. For reprocessing please check this http://goo.gl/8aAcz. Thanks.

Hello...
http://help.sap.com/saphelp_nw70/helpdata/en/87/13843b74f7be0fe10000000a114084/frameset.htm
I understand the help topics are difficult to find...
Some tips:
- use only local objects (create infopackages localy in the production client to build the process chains, so you don't have to transport them).
- the secret for good process chain is organization. Separate texts, attributes and transactional data in separated process chains. Use a "master" global process chain to call the sub-process chains.
- careful assure the necessary precedences. Make sure you load attribues and activate the master data before the transactional data.

This is regarding process chains

hi this is satish
actually if i am running 10 pc"s now i am monitoring screen .suppose second pc has faile and to reveal the error it takes much time , but i want to continue with remaining pc loads
is there any solution for this
advance thanks

hi akila,
In RSPC screen go to Settings->Default chains-->Do not suggest.
By doing this the system won't suggest the process by it self.
Are you sure those are error messgaes or warnings?
If its warning just activate them.
Its always necessary to activate the ODS after data loading,for reporting purpose.
Try with your own variant and process.
Also activate the ODS manually before scheduling process chains.
hope it helps.
bye!!!!!!

Interview questions in process chain

hi
cany any one send me possible interview questions in process chain and errors with answer.
thanks in advance
pradeep

Hi Pradeep
1.Procedure for repeat delta?
You need to make the request status to Red in monitor screen and then delete it from ODS/Cube. Then when you open infopackage again, system will prompt you for repeat delta.
also.....
Goto RSA7->F2->Update Mode--->Delta Repetation
Delta repeation is done based on type of upload you are carrying on.
1. if you are loading masterdata then most of the time you will change the QM status to red and then repeat the delta for the repeat of delta. the delta is allowed only if you make the changes.
and some times you need to do the RnD if the repeat of delta is not allowed even after the qm status id made to red. here you have to change the QM status to red.
If this is not the case, the source system and therefore also the extractor, have not yet received any information regarding the last delta and you must set the request to GREEN in the monitor using a QM action.
The system then requests a delta again since the last delta request has not yet occurred for the extractor.
Afterwards, you must reset the old request that you previously set to GREEN to RED since it was incorrect and it would otherwise be requested as a data target by an ODS.
Caution: If the termianted request was a REPEAT request itself, always set this to RED so that the system tries to carry out a repeat again.
To determine whether a delta or a repeat are to be requested, the system ONLY uses the status of the monitor.
It is irrelevant whether the request is updated in a data target somewhere.
When activating requests in an ODS, the system checks delta repeat requests for completeness and the correct sequence.
Each green delta/repeat request in the monitor that came from the same DataSource/source system combination must be updated in the ODS before activation, which means that in this case, you must set them back to RED in the monitor using a QM action when using the solution described above.
If the source of the data is a DataMart, it is not just the DELTARNR field that is relevant (in the roosprmsc table in the system in which the source DataMart is, which is usually your BW system since it is a Myself extraction in this case), rather the status of the request tabstrip control is relevant as well.
Therefore, after the last delta request has terminated, go to the administration of your data source and check whether the DataMart indicator is set for the request that you wanted to update last.
If this is NOT the case, you must NOT request a repeat since the system would also retransfer the data of the last delta but one.
This means, you must NOT start a delta InfoPackage which then would request a repeat because the monitor is still RED. For information about how to correct this problem, refer to the following section.
For more information about this, see also Note 873401.
Proceed as follows:
Delete the rest of this request from ALL updated data targets, set the terminated request to GREEN IN THE MONITOR and request a new DELTA.
Only if the DataMart indicator is set does the system carry out a repeat correctly and transfers only this data again.
This means, that only in this case can you leave the monitor status as it is and restart the delta InfoPackage. Then this creates a repeat request
In addition, you can generally also reset the DATAMART indicator and then work using a delta request after you have set the incorrect request to GREEN in the monitor.
Simply start the delta InfoPackage after you have reset the DATAMART indicator AND after you have set the last request that was terminated to GREEN in the monitor.
After the delta request has been carried out successfully, remember to reset the old incorrect request to RED since otherwise the problems mentioned above will occur when you activate the data in a target ODS.
What is process chain and how you used it?
A) Process chains are tool available in BW for Automation of upload of master data and transaction data while taking care of dependency between each processes.
B) In one of our scenario we wanted to upload wholesale price infoobject which will have wholesale price for all the material. Then we wanted to load transaction data. While loading transaction data to populate wholesale price, there was a look up in the update rule on this InfoObject masterdata table. This dependency of first uploading masterdata and then uploading transaction data was done through the process chain.
What is process chain and how you used it?
A) We have used process chains to automate the delta loading process. Once you are finished with your design and testing you can automate the processes listed in RSPC. I have a real time example in the attachment.

Changing the Background server information of mulitple process chains

Hello Friends,
I am looking for a program or any other way by which I can modify the Background server information of mulitple process chains at once.
I am not really sure whether we have any such programs. Any help would be highly appreciated.
Thanks,
Vinoth V

Hi Vinoth,
RSPCCHAINATTR table can give information regarding process chain list with server names. you can create custom program to modify it. Input parameters can be process chain name and server name.
But you need to take care of authorizations for this table.
Hope this helps.

How to handle delta failed process chain steps

Hi All,
I have a query regarding process chains were in processstep has delta load and there is dependency between the predeseccor and successor process steps,then
if the delta load fails due to any one of the following reasons
1) due to remote_icp locked the prtclr Infoobject the process step is executing .
2) due to any psa records errors and so on
Then how to handle delta and see that correct delta records were updated .
Because again for the nextday loads if the previous delta is incorrect it will give pop-up message that it is not possible.
If any suugestions pl guide me.
thanks
Venkat

1)Remove the lock by force from sm12 or wait till the lock is gone.Then see if the delta data has come till the PSA.Mark failed delta load RED and back it out from target.Then read everything in manually from PSA to target.
In process chains u can go the monitor entry for the failed load by..highlight chain..click log icon..give selection..for proper selection..see the failed node..right click..display messages..click on process monitor.
Sometimes even if infopackage is run successful manually,next steps in the chain do not kick off.
Use Siggi's excellent blog on this..(it works really well)
/people/siegfried.szameitat/blog/2006/02/26/restarting-processchains
2)Make request RED and back it out from target.
Correct records in the PSA and read everything in manually from PSA to data target.
Then use Siggi's blog.
If data hasnt come to PSA do a delta repeat.
Always check yesterday's chain run about 1-2 hrs before today's chain kicks off.
cheers,
Vishvesh

How can i understand the Process Chain management in real time!!!

Hi,
now i am learning BW concepts. now i would like to know the real time scenarios regarding Process chains. can any body help me in this matter?.
thanks,
stikanth.ch

Hi,
A process chain is a defined sequence of interdependent processes required to perform acomplex task in an SAPBW environment. Data maintenance tasks in SAPBW are notrestricted to uploading data. Aggregate rollups, index maintenance, master data and ODS activation, and a variety of other jobs are required to update data, guarantee best-possible performance, and maintain data integrity. Typical SAPBW implementa-tions have complex interdependent networks of jobs in place that run every night, week,or month.Previous releases of SAPBW did not provide an integrated solution for scheduling and monitoring those kinds of job networks. This has changed with the introduction of process chains in release 3.0. Process chains allow you to define complex job networks consisting of standard SAPBW jobs, as well as custom jobs; they support visualizing the job network and centrally controlling and monitoring the processes.

Error in adding remote process chain to existing one

Hi all,
when I try to add an remote process chain to an existing one I get an error. I created a variant for the remote call. I entered the destination and when I try to choose the remote process chain I get the following error:
Error in remote call of destination
The following error occurred during the remote function call for destination XY:
Dynproausgabe ohne Verbindung zum Benutzer (Sorry error message is in german)
I checked the RFC and it is working. On the testsystem things were ok. On productive system it doesn't work... No I can not transport since the regarding process chain is only existing on productive.
Thanks for any hints
Stefan

you can check out SAPNOTE 659160.

Local process chain is failing and i want to run its successor chain

Hello All,
I have a query regarding process chain, which is :
I have a metachain, in which some local chains are existing.
If suppose local process chain 2 is failing and i don't want to run that i want to run local process 3 directly
(which is successor of chain 2 ).
What should i do?
Regards,
Dolly

Hi,
You can trigger the process chain as below:
Go to TC SE37 -
> use function module RSPC_CHAIN_START -
> execute -
> put your process chain's technical name in variant I_CHAIN -
> Execute -
> specify job priority
Cheers

Transporting Process Chain

Hi All,
I have an existing process chain scheduled on daily basis in the prod environment. I want to change the process chain by adding some data load steps.
My question is, if I move the modified PC from dev to production. will the process chain be removed from daily schedule? I mean do I need to reschedule the process chain? or this change will not affect the process chain schedule?
Experts Pls advise.
Note: Pls do not get confused with my other post regarding process chain, that is related to meta chain.
Regards,
Anand

Hi Anand,
I also had such scenario in my project where i had to add some more data loading and index creation & deletion steps in my process chain. I did created a copy chain in development system and made modifications to the old chain & saved a copy of that chain in devlopement. Performed testing of the chain in Accpetance & Quality & then moved to production. You can also follow the same path so as to make sure that in case if you face issues faced if any, with the newly developed chain, then your old one is inctact and bussiness is not affected due to the issues in the newly created chain.
Once your new chain is succesfull you can move it to production and schedule the new chain and remove the old chain from schedule. This will ensure that the bussiness is not impcated due to this change.
Also one more thing to be remembered is that before you transport a chain to production make sure that you Metachain chain and the other Local Chains in the Metachain should have their start variant set to a future date or select the variant to "Run using Metachain or API" else as soon as the chain is moved to production it starts running automatically.
Hope this info clears you doubts.
Thanks

Process Chains - Production Support

Hi Gurus,
I have doubt regarding process chains in production support system. Is the consultant who is working on production support on process chains monitoring, how many process chains are assigned to him( maximum). Is all the process chains are related to application specific, i mean like all the process chain related to SD, FICO, MM, and so on or from any application.
Thanks in Advance..........
Regards
Ramakrishna Kamurthy

Hi Ramakrishna,
Process Chains can be triggered as Batch Jobs ... After completing the batch Job the consultant checks for any failure in process chain or whether the batch job run successfully or not.
More over Process chains are categorised and triggered based on how much time they are consuming to Load the Data.. normally first Master Data Chains will be triggered and then Transactional Data Chains
So there will not be any count that a Consultant assigned with how many chains in production support, as its totally depends on the Batch Jobs triggered ....
Hope this helps,
Sudhakar.

Regarding "Delete Index" process in the process chain.

Hi Gurus
In the process chain, I have Delete Index -> Load Info pacakge -> Create Index process in the above order.
I am loading few records, so no need to delete indexes everytime. Can i remove the "Delete Index" process from the Chain without deleting the Create Index process. Or do I have to delete both.
Could you please clarify my doubt if possible in detail.
Thanks,
Regards,
aarthi

With the numbers you provided, you probably don't need to have the steps. With Oracle (not sure about all the other DB flavors) there are some other considerations:
Not having the indexes when loading the data can improve the load time since the bitmap indexes are not very efficient with respect to inserts/updates. The more dimensions you have, the more indexes there will be and the more noticable the impact of having the indexes present when loading.
The drop index process only drops the F fact table indexes. If you compress your cubes regularly so that you don't have many uncompressed requests, the index rebuild time will remain small, but if you have many uncompressed requests in your cube, the index rebuild time can begin to exceed whatever time you might save on the load with indexes deleted.
With bitmap indexes present, you can also occasionally receive a ORA-0600 deadlock error during the load process, and that can be prevented by dropping the indexes before loading or chose the load option packet by packet so that two packets are not trying to update the same index block at the same time.
Another concern in shops where reporting on the cube might occur during the load process - if you drop indexes prior to a load, any one trying to run a query on teh cube could have poor query performance since all the indexes will be missing onthe F fact table, this agina becomes more apparent the more data you have in the uncompressed fact table.
So it really comes down to your environment, but certainly drop the indexes any time you have large loads.
