Question about repeating in the process chain

Hello Gurus,
        my DTP is set as "valid records update, no reporting (request red)", and put into a process chain. the process chain goes wrong on this DTP due to some erroneous records. my questions are:
   (1) based on DTP configuration, all the records are transferred to target successfully except for those erroneous records. is that right?
   (2) after I correct those erroneous records in PSA, I repeat this DTP process in the process chain. what exact data are transferred by this repeating operation on this DTP? do we need to take care of all the previously loaded data for this subsequent repeat loading ?
Many thanks.

Hi ,
Please refer my article for your answer, also this has lots of good DTP features.
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/10339304-7ce5-2c10-f692-fbcd25915c36?quicklink=index&overridelayout=true
(1) based on DTP configuration, all the records are transferred to target successfully except for those erroneous records. is that right?
Yes. All the erroneous records go in the error stack and then you can fix the errorneous records there and execute the error DTP.This setting ensures, incorrect/incomplete data is not available for reporting.
(2) after I correct those erroneous records in PSA, I repeat this DTP process in the process chain. what exact data are transferred by this repeating operation on this DTP? do we need to take care of all the previously loaded data for this subsequent repeat loading ?
No records are transferred on repeating teh job. We need to manually set the status of request to Green.Yes we need to take care of all the subsequent steps.

How to kill the process chain

hi,
I have question how to kill the process chain during running.
thank you.

Hi
If the process chain is running in background,
goto SM37
Give * in the jobname
Give the username who scheduled the process chain
Job status - check the check boxes - SCHED, relased, ready, active
click execute.
It displays all the process chains that, scheduled & running.
You can select the process chain that need to be stopped & click STOP active job or ctrl+F1.
Hope this helps!
Kindly award points for all useful answers.
If you post the BW related queries in the BI general forum, you will get more answers.

How to schedule the process chain fr the report

hai experts,
i have a query which i need to generate for every five hours? i know that we can generate the report thr process chain but i dont know how to build that..
my question is how to schedule the report,how to build the process chain,....
can any one plz tell me how to start this generating report for every five hours
thanks in advance..points will be alloted surely ,i need this urgently..

First of all you need to Identify the InfoObjects if you want to take up Master Data Loads, and if you want take up transaction loads then select the Data Targets to which the data has to be updated. Then plan the dataflow accordingly.
You want to create a Process Chain, Go to RSPC, and then select the create option and from the Process categories available on the left handside drag and drop the Start process, then define the Variant for the same. In the same way you need to identify the other Process Types available on the lefthand side. For Eg: Start Process>Load to ODS>Activation of ODS Data>Delete Indexes for the InfoCube>Load to InfoCube>Create Indexes>Delete Overlapping Req-->Agg. Rollup.
This is how you need to specify the dataflow, several other Process Types also included based on the requirement For Eg: Sending Mail Alerts when the Job is Success or Terminated.
Also, have a look at this links to make urself clear about the steps in creating Process Chain.

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.

Error while running the process chain

Hi, I am getting following error while running the process chain.
"Lock NOT set for: Deleting the data completely from a data target"
Please suggest.
amit

hi,
This is due to a lock on the objects which is being used by ur load.
Even if master data used by this would be in a lock by an attribute change run. wait till that attribute change run finishes and then repeat.
If this target itself is locked by someother process like rollup , compression , this error would appear. In this case also repeat the step after those locking process finish.
some general locks during loading:
Sometimes parallel processing in DTP might lead to this, its better set the DTP and infopackage in serial processing. In this case change the settings and then repeat the process.
There is a specific case in which the Serial DTP gets locked by itself, in this case repeat it untill it succeeds.
You can identify the above scenario as below. This is applicable only if the DTPs processing mode is serial.
if u see in SM 37 this load would have three DTP processes running.
it should have only two.
In this case cancel the process and repeat it untill u get it right.
hope this helps u
regard,
ranjith

Error while executing the Process chain

Hi Friends,
The process chain that I scheduled is getting failed at the Infopackage loading stage.
On checking the diplay message, I found the following log:
Cannot stage requested data for datasource
Error in source system
I activated the datasource in source system, then replicated the same and tried to load data.
But the issue remains the same.
I checked in RSA7. The status corresponding to this datasource is in yellow status.
Can I delete this entry and try again?
Please suggest.
Thanks in advance.

Dead Locks
2. Error in unit conversion
Units of measure
3.Error 1 in update
When Src file is already open or not accessible.
4.Processing no data
theres no data selected after extraction
5.Caller 70 missing
" This error normally occurs whenever BW encounters error and is not able to classify them. There could be multiple reasons for the same
1) Whenever we are loading the Master Data for the first time, it creates SIDs. If system is unable to create SIDs for the records in the Data packet, we can get this error message.
2) If the Indexes of the cube are not deleted, then it may happen that the system may give the caller 70 error.
3)Whenever we are trying to load the Transactional data which has master data as one of the Characteristics and the value does not exist in Master Data table we get this error. System can have difficultly in creating SIDs for the Master Data and also load the transactional data.
4) If ODS activation is taking place and at the same time there is another ODS activation running parallel then in that case it may happen that the system may classify the error as caller 70. As there were no processes free for that ODS Activation.
5) It also occurs whenever there is a Read/Write occurring in the Active Data Table of ODS. For example if activation is happening for an ODS and at the same time the data loading is also taking place to the same ODS, then system may classify the error as caller 70.
6) It is a system error which can be seen under
the Status tab in the Job Over View.
solution:
" If the Master Data is getting loaded for the first time then in that case we can reduce the Data Package size and load the Info Package. Processing sometimes is based on the size of Data Package. Hence we can reduce the data package size and then reload the data again. We can also try to split the data load into different data loads
If the error occurs in the cube load then we can try to delete the indexes of the cube and then reload the data again.
If we are trying to load the Transactional and Master Data together and this error occurs then we can reduce the size of the Data Package and try reloading, as system may be finding it difficult to create SIDs and load data at the same time. Or we can load the Master Data first and then load Tranactional Data
If the error is happening while ODS activation cause of no processes free, or available for processing the ODS activation, then we can define processes in the T Code RSCUSTA2.
If error is occurring due to Read/Write in ODS then we need to make changes in the schedule time of the data loading.
Once we are sure that the data has not been extracted completely, we can then go ahead and delete the red request from the manage tab in the InfoProvider. Re-trigger the InfoPackage again.
Monitor the load for successful completion, and complete the further loads if any in the Process Chain.
6.Idoc not processed completely.
Here the request remains yellow (in process) and with the same details (as seen in the details tab of the monitor) for an abnormally long time. Many-a-times, the port for communication is not open and re-starting the load helps. For long running jobs, it may not be advisable to restart the extraction
Contact the BASIS administrator to push the IDOC.

Authorizations setting for running the process chain

Hai
Iam planning to run the process chain for loading the data into ODS. But i dont have authorization for it.
so what are the authorizations i need to run the process chain in my system. And how can i set all those authorizations to my user-id. I have all authorization rights .
Pls let me knw
kumar

Hi,
Authorizations for Process Chains
Use
You use authorization checks in process chain maintenance to lock the process chain, and the processes of the chain, against actions by unauthorized users.
·        You control whether a user is allowed to perform specific activities.
·        You control whether a user is allowed to schedule the processes in a chain.
The authorization check for the processes in a chain runs when the system performs the check. This takes place upon scheduling or during synchronous execution. The check is performed in display mode. The check is performed for each user that schedules the chain; it is not performed for the user who executes the chain. The user who executes the chain is usually the BI background user. The BI background user automatically has the required authorizations for executing all BI process types. In attribute maintenance for the process chain, you can determine the user who is to execute the process chain.
See also: Display/Maintenance of Process Chain Attributes ® Execution User.
Features
For the administration processes that are bundled in a process chain, you require authorization for authorization object S_RS_ADMWB.
To work with process chains, you require authorization for authorization object S_RS_PC. You use this authorization object to determine whether process chains can be displayed, changed or executed, and whether logs can be deleted. You can use the name of the process chain as the basis for the restriction, or restrict authorizations to chains using the application components to which they are assigned.
Display/Maintain Process Chain Attributes
Use
You can display technical attributes, display or create documentation for a process chain, and determine the response of process chains during execution.
Features
You can display or maintain the following attributes for a process chain:
Process Chain ® Attribute ® ...
Information
Description
( Rename)
You can change the name of the process chain.
Display Components
Display components are the evaluation criterion in the process chain maintenance. Assigning the process chains to display components makes it easier to access the chain you want.
To create a new display component, choose Assign Display Components in the input help window and assign a technical name and description for the display component in the Display Grouping dialog box that appears.
Documents
You can create and display documents for a process chain.
For more information, see Documents.
Last Changed By
Displays the technical attributes of the process chain:
·        When it was last changed and who by
·        When it was last activated and who by
·        Object directory entry
Evaluation of Process Status
If you set this indicator, all the incorrect processes in this chain and in the overall status of the run are evaluated as successful; if you have scheduled a successor process upon error or always.
The indicator is relevant when using metachains: Errors in the processes of the subchains can be evaluated as unimportant for the metachain run. The subchain is evaluated as successful, despite errors in such processes of the subchain. If, in the metachain, the successor of the subchain is scheduled upon success, the metachain run continues despite errors in unimportant processes of the subchain.
Mailing and alerting are not affected by this indicator and are still triggered for incorrect processes if they have an upon error successor.
Polling Indicator
With this indicator you can control the response of the main process for distributed processes. Distributed processes, such as the load process, are characterized as having different work processes involved in specific tasks.
With the polling indicator you determine whether the main process needs to be kept until the actual process has ended.
By selecting the indicator:
-         A high level of process security is guaranteed, and
-         External scheduling tools can be provided with the status of the distributed processes.
However, the system uses more resources; and a background process is required.
Monitoring
With the indicator in the dialog box Remove Chain from Automatic Monitoring?, you can specify that a process chain be removed from the automatic monitoring using CCMS.
By default CCMS switches on the automatic process chain monitoring.
For more information about the CCMS context Process Chains, see the section BW Monitor in CCMS.
Alerting
You can send alerts using alert management when errors occur in a process chain.
For more information, see Send Alerts for Process Chains.
Background Server
You can specify here on which server or server group all of the jobs of a chain are scheduled. If you do not make an entry, the background management distributes the jobs between the available servers.
Processing Client
If you use process chains in a client-dependent application, you can determine here in which client the chain is to be used. You can only display, edit, schedule or execute the chain in this client.
If you do not maintain this attribute, you can display, edit, schedule or execute the process chain in all clients.
Process variants of type General Services that are contained in a process chain with this attribute set will only be displayed in the specified client.
This attribute is transported. You can change it by specifying an import client during import. You must create a destination to the client set here in the target system for the import post processing (transaction RSTPRFC) The chain is activated after import and scheduled, if necessary, in this client.
Execution User
In the standard setting a BI background user executes the process chain (BWREMOTE).
You can change the default setting so that you can see the user that executes the process chain and therefore the processes, in the Job Overview. You can select the current dialog user who schedules the process chain job, or specify a different user.
The setting is transported.
The BI background user has all the necessary authorizations to execute all BI process types. Other users must assign themselves these authorizations so that authorization errors do not occur during processing.
Job Priority
You use this attribute to set the job priority for all of the jobs in a process chain.

SET CURRENT DEGREE = 1..error when run the process chain..

Hi Experts,
when i run the process chain , i got the following error..
SET CURRENT DEGREE = 1..
what is this error?
Kindly help ..

hi,
As BW reporting queries are often CPU-intensive and geneally executed in parallel.
Parallel processing is activated dynamically in the SAP BW system for every reporting query CURRENT DEGREE = ANY and itsdefault value is 1.
you can limit the maximum number of parallel tasks using ZPARM PARAMDEG(maximum number of parallel tasks ) for the no. of parallel processors for its usuage and this should match no. of processors you can get touch with your basis team
check SAP Note:390016 -DB2/390: BW: Database settings and performance ; in that look at query parallelism it explain about this
hope it helps

Where to check the user id that who deleted the process chain

Dear Gurus,
If the process chain is deleted accidentally, can we check the user id used to delete. Where can we see the logs/information about that.
Regards
Ram

Hi Ram,
When you delete something in BW/BI, a background job is assigned to the requested task.
To check the same use Tcode SM37, provide details: Job name as BI_DEL*, user name as *, Job status as Finished, and the date or date range in which the process chaing was deleted. Then execute the request.
It will show you all the jobs which were used to delete something in the BW/BI.
Check the log of the request and you will get the required information.
Cheers...

How can u know the process chain total time, individual time?

Hi guru's
How can u know the process chain total time, individual time?
and what options will available in sm37?
Thanks
prabha reddy

Hi Prabha
Iam not very sure about total time and individual times.
But you can go to tcode rspcm for monitoring the daily process chains. it gives you details like 1. status 2.start date & time 3. Log ID of each process chain.
or you can go to log view of particular individual chain to know how long it has run.
SM37: tcode for simple job selection.
here you check the status of job.
you can select for certain conditions like
1. scheduled
2. released
3. ready
4.active
5. cancelled

Function module used to restart the process chain in the middle?

Hi all,
can anyone pls let me know the function module to restart the process chain in the middle of the process chain?
I need to run the process chain from the middle which can be done through a function module can anyone pls let me know!!
Thanks
pooja

what exactly your requirement is?
You can't trigger the process in the middle either it should be trigger by start variant or it's predessor.
If your chain failed in the middle - you can fix the prob and can do 'Repeat' option or you can also use FM 'RSPC_PROCESS_FINISH . (this FM will work only if the chain fails)

Event is not getting triggered in the process chain

Hi,
We had a process chain which was triggered by an Event, and it was running fine until few days ago. So I removed the chain from schedule and re-scheduled it again with these details:
File load: every 2 hrs
Process chain setting
Immediate tab: start immediately
After event: "event name" and "parameter name" and periodic job: ticked
I activated the chain and scheduled it. But the event is not triggered and the chain does not start. I even tried to trigger the process chain manually in sm64 but the process chain did not start.
Can someone please tell me steps to automate the event triggering and also any setting that should be taken care off in the info package and the process chain.
Thanks In advance.
Ram

Hello Ram, to start your Process Chain by an event, then you need to maintain the Start process of the process chain.
Select "Direct Scheduling".
In the Change Selections, press After Event. Put your event name and parameter (if any). Also click on Periodic job.
Press Save. Then Activate and Schedule your process chain. All your processes should turn green.
To verify, right-click on the Start process and select Displaying Scheduled Job(s).... You should see a job called BI_PROCESS_TRIGGER in a Released status. You can click on the job and look at the start conditions.
When you go to trigger the event, use the same event name and parameter (if any) as in the start condition. Your process chain will then execute. To insure, use RSPC to view your process chain and press the Logs icon (last one at the top).
Does this help?

To find the time required by the process chain to complete

Hi Experts,
I am calulating the average time required by the process chain to compete.
Is there any way to find the time required by the process chain to complete..
Thanks in advance.
Regards,
Ashwin

Hi,
There is a Tool provided by SAP to do the Process Chain Analysis.
It is basically a ABAP Program /SSA/BWT which provides the following BW Tools:
a)Process Chain Analysis : this tool is used to perform the Runtime analysis of the Process Chains. The analysis can be performed not only at Process Chain level but also at the Process Type level.
b)Detailed Request Analysis
c)Aggregate Toolset
d)Infoprovider BPPO Analysis
So you can go through the program and analyse the runtime of your Process Chains.
