Complex process chain

Hi,
I need to create a process chain based on a event.
From ECC i got a program that sends same event multiple times a day.
The conditions are given below,
1. Process chain must be scheduled to wait for the event.
2. If the event is received between time '020000' and '050000.
    then the proces chain must proceedfurther
   else
   it must not proceed and wait.
can this be achieved via process type ABAP program or any other best possibility?

Hey Again.
Ok, I think you probably won't be able to do this with the decision between multiple alternatives. Well, actually you could but it would take some extra work. I've implemented custom formulas where I am and have created some for checking if a chain is active, a process is active, a chain has completed, etc... To get there though you have to first implement custom formulas. it isn't difficult and can be extremely helpful (at least I have found them to be). In case you are interested, here is a link to get you started on that effort (I think it's worth it even if not for this project):
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/f095592f-42f7-2a10-6ab1-c836a559b48f
So, while the solution could very well be done using a mix of custom formulas and the decision element it is probably best to simplify and use a custom abap program. You have two choices, do this on the ECC side or on BW side.
If done in ECC:
1) Create log table, or utilize existing one
2) Check table... if event has been raised today, then do not raise event again.
If done in BW:
1) Create a chain where starter uses the even and parameter that will be raised from ECC
2) Create a custom ABAP program that checks if the chain has run yet today. If not, it would raise another event to trigger the chain doing the actual processing. If the chain has run today, the event is not raised.
While ECC side may seem simpler, you would be completely reliant on them not accidentally triggering the chain twice in one day. So i would go with doing it on the BW side. You can definitely check if a chain has run today and also if it has finished successfully. Here is a list of some process chain related tables that you may find useful:
RSEVENTCHAIN - Event Chain Processing Event Table
RSEVENTHEAD - Header for the event chain
RSEVENTHEADT - Header for the event chain
RSPCCHAIN - Process chain details
RSPCCHAINATTR - Attributes for a Process Chain
RSPCCHAINEVENTS - Multiple Events with Process Chains

Process chains - Process type ends with complex status

Hi all
does anyone know how to use this functionality ? I've created a custom process type that ends with complex status. I assume I assign the different statuses with parameter E_STATE. But how do I retrieve the status in the process chain ?
Thanks a lot.
Eli G

Hi,
We have two connected links in the process, one to continue the process chain when process status is green and other link to red status. The problem is the process status remains yellow until our confirmation in pop-up.
The process chain should be started by user in web browser. So, it isn't possible run it in background.
Thank you,

Configuration Guide for Transaction Banking Process Chain - 0TB_DM_INIT_P01

Hi All,
Just wondering whether there is any Configuration Guide available for various Transaction Banking Process Chains, like, [0TB_DM_INIT_P01|http://help.sap.com/saphelp_nw70/helpdata/en/7e/0d6a99cbdf4873998b533e088b6a1b/frameset.htm], etc.
These process chains in Activity Status Coversion (i.e. Dormancy management) are quite complex and I have been able to activate the chains - but while running some of the processes are giving errors...
So, was wondering whether any Building Block Configuration Guide like CRM Analytics (or, others) available or not?
If not, should I just open an OSS ticket to get official guide from SAP?
Thanks for help.

How to test Process chain in BW

Hi Guys,
Can U give me some introduction to Process chains and how to test it in BW 3.5
Thanks for Ur time.
Cheers
Senthil

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.

Testing
We need to test the PC chains.
You need to test if the extractions are working fine, data is getting loaded into targets, post load activities like activation, rollup, compression etc are successfull etc.
We schedule / trigger the chains and monitor them. We ensure that all the process types are happening successfully.
One major area we concentrate on is to identify dependcies in the chain. This will ensure less erros and also reduce chain timings by a great extend. Dependencies should be kept to a minimum whereever possible.
Also in cases where we use events/third party shceduling tools to trigger BW chains we check that out.

Reg: Process Chain, query performance tuning steps

Hi All,
I come across a question like, There is a process chain of 20 processes.out of which 5 processes are completed at the 6th step error occured and it cannot be rectified. I should start the chain again from the 7th step.If i go to a prticular step i can do that particular step, How can i start the entair chain again from step 7.i know that i need to use a function module but i dont know the name of FM. Please somebody help me out.
Please let me know the steps involved in query performance tuning and aggregate tuning.
Thanks & Regards

Hi,
Process Chain
Method 1 (when it fails in a step/request)
/people/siegfried.szameitat/blog/2006/02/26/restarting-processchains
How is it possible to restart a process chain at a failed step/request?
Sometimes, it doesn't help to just set a request to green status in order to run the process chain from that step on to the end.
You need to set the failed request/step to green in the database as well as you need to raise the event that will force the process chain to run to the end from the next request/step on.
Therefore you need to open the messages of a failed step by right clicking on it and selecting 'display messages'.
In the opened popup click on the tab 'Chain'.
In a parallel session goto transaction se16 for table rspcprocesslog and display the entries with the following selections:
1. copy the variant from the popup to the variante of table rspcprocesslog
2. copy the instance from the popup to the instance of table rspcprocesslog
3. copy the start date from the popup to the batchdate of table rspcprocesslog
Press F8 to display the entries of table rspcprocesslog.
Now open another session and goto transaction se37. Enter RSPC_PROCESS_FINISH as the name of the function module and run the fm in test mode.
Now copy the entries of table rspcprocesslog to the input parameters of the function module like described as follows:
1. rspcprocesslog-log_id -> i_logid
2. rspcprocesslog-type -> i_type
3. rspcprocesslog-variante -> i_variant
4. rspcprocesslog-instance -> i_instance
5. enter 'G' for parameter i_state (sets the status to green).
Now press F8 to run the fm.
Now the actual process will be set to green and the following process in the chain will be started and the chain can run to the end.
Of course you can also set the state of a specific step in the chain to any other possible value like 'R' = ended with errors, 'F' = finished, 'X' = cancelled ....
Check out the value help on field rspcprocesslog-state in transaction se16 for the possible values.
Query performance tuning
General tips
Using aggregates and compression.
Using less and complex cell definitions if possible.
1. Avoid using too many nav. attr
2. Avoid RKF and CKF
3. Many chars in row.
By using T-codes ST03 or ST03N
Go to transaction ST03 > switch to expert mode > from left side menu > and there in system load history and distribution for a particual day > check query execution time.
/people/andreas.vogel/blog/2007/04/08/statistical-records-part-4-how-to-read-st03n-datasets-from-db-in-nw2004
/people/andreas.vogel/blog/2007/03/16/how-to-read-st03n-datasets-from-db
Try table rsddstats to get the statistics
Using cache memoery will decrease the loading time of the report.
Run reporting agent at night and sending results to email.This will ensure use of OLAP cache. So later report execution will retrieve the result faster from the OLAP cache.
Also try
1. Use different parameters in ST03 to see the two important parameters aggregation ratio and records transferred to F/E to DB selected.
2. Use the program SAP_INFOCUBE_DESIGNS (Performance of BW infocubes) to see the aggregation ratio for the cube. If the cube does not appear in the list of this report, try to run RSRV checks on the cube and aggregates.
Go to SE38 > Run the program SAP_INFOCUBE_DESIGNS
It will shown dimension Vs Fact tables Size in percent.If you mean speed of queries on a cube as performance metric of cube,measure query runtime.
3. --- sign is the valuation of the aggregate. You can say -3 is the valuation of the aggregate design and usage. ++ means that its compression is good and access is also more (in effect, performance is good). If you check its compression ratio, it must be good. -- means the compression ratio is not so good and access is also not so good (performance is not so good).The more is the positives...more is useful the aggregate and more it satisfies the number of queries. The greater the number of minus signs, the worse the evaluation of the aggregate. The larger the number of plus signs, the better the evaluation of the aggregate.
if "-----" then it means it just an overhead. Aggregate can potentially be deleted and "+++++" means Aggregate is potentially very useful.

4. Run your query in RSRT and run the query in the debug mode. Select "Display Aggregates Found" and "Do not use cache" in the debug mode. This will tell you if it hit any aggregates while running. If it does not show any aggregates, you might want to redesign your aggregates for the query.
Also your query performance can depend upon criteria and since you have given selection only on one infoprovider...just check if you are selecting huge amount of data in the report
Check for the query read mode in RSRT.(whether its A,X or H)..advisable read mode is X.
5. In BI 7 statistics need to be activated for ST03 and BI admin cockpit to work.
By implementing BW Statistics Business Content - you need to install, feed data and through ready made reports which for analysis.

You can go to T-Code DB20 which gives you all the performance related information like
Partitions
Databases
Schemas
Buffer Pools
Tablespaces etc
use tool RSDDK_CHECK_AGGREGATE in se38 to check for the corrupt aggregates
If aggregates contain incorrect data, you must regenerate them.

Best way to know correct forecast model - process chain set up with multiple forecast models

Hi Experts,
I need your help in selecting best forecast model for our company. We have some of the models already used for our company, and because of multiple models used it is taking very long time for process chain to finish. There is no existing documentation available on which model was used why initially. Please help me to make out forecasting process smooth.
- What is the best way to know, which forecast model is correct and should be used for our forecasting process.
- In case multiple forecasting models are really required to be used, please suggest ways to optimally schedule them in process chain.
- At times we get messages like "not enough data available" for specific model - any way to avoid this.
- How to optimally use parallel processing profiles forecasting process in process chain.
- Things which should be avoided.
Request your help, please share your experiences.
Regards
NB

Hi Neelesh,
There are many points you need to consider to redesign forecast process for your company/client.
You need to select the best suited forecast model first depending on the business. This has to be well tested & agreed by business users. Complexity will be an outcome of this exercise with business users. Best id to give then a brief intro on all available models & then help them selection the best one as per their requirement.
Auto selection models are generally more time taking & should be used only when you have no idea at all on the business/demand pattern.
Run time will depend how you are clubbing the CVCs to get the forecast generated & also parallel processing. For parallel processing profile you will need to do trial & error testing along with help from Basis team on how many free dial up processes are available.
Even you can run many forecast calculations in parallel if the product/cvcs are totally different. - As per my personal experience maximum run time reduction can be achieved here.
Daily run is not advisable except only for businesses where you have too much dynamism in demand planning i.e. you expect the demands to be changed overnight. Most of the companies run forecast on monthly basis or at weekly basis at the max.
"Not Enough data" will be a problem if you are having the irrelevant models used in forecast profiles. This means users are not bothered to maintain the needed data for he forecast calculations or they are not aware at all of the situation. Running such models on daily basis is not advised at all. Better users should use interactive forecasting & saving the results in such cases.
Just to give a crude example we get forecast calculated on monthly basis for approximately 4 lac cvcs in less than 3 hrs using moving avg, seasonal linear regression, seasonal trend, croston models. We use parallel profiles also everywhere with 10 blocks & 500 cvc/block.
Hope this helps. Let me know if you have nay more questions & also the results using any of this.

How to Delay an Event in a Process Chain

Hey,
We have a scenario in which we need to schedule a process chain in such a way that,the main chain contains the DSO load and the local chains contains the Cube load (One for NA and other for EU).
I want to schedule it in such a way that two local chains of the main chain should be triggered at different times.

hi...
I think its getting pretty complex....instead of writing programs..use simle metachain thing which will solve your issue with simple process chain design.
You have :
Main Chain
{Dso load
Local Chain A(Eu) Local Chain B(Na)
Now what you want is on the first run the main chain should trigger and only Local Chain A trigger.
While on second run
Main chain + Local chain B trigger.
the simplest soultion
Create 2 Metachains like below:
PC1.
Main Chain X
{Dso Load
Local Chain A(Eu)
PC2.
Main chain Y
{Dso Load
Local Chain B(Na)
Now create metachain to combine
Main Chain
{PC1
PC2
So PC2 will start only when the PC1 has finished.
Let me know if it is feasible for you.

Batch program to replicate DataSources in process chains

Hi everybody,
I am looking for a batch program to replicate DataSoruces in a BW 3.5 system. I would like to use this program at the beginning of process chains, in order to avoid any potential problems from transports into productive environment.
I found the following program already but it seems not to work: RSAOS_METADATA_UPLOAD_BATCH
thanks in advance for any help
Ulrich

Hi John
thanks for the hint. Of course you are right. I would expect to have also a transport in BW. It happend unfortunately several times, that not only the involved DataSource got inactivated in our complex data model, but also other ones.
That's why I look simply for the program that replicates DataSources. I tried already with tracing in via SM30 - unfortunately no useful results

Advise in process chain design

Dear Experts,
          I have a complex issue here in case of design of a process chain. In our system, data is loaded from R/3 to ODS1 -ODS2-Cube.
The data is loaded to the ODS1 and ODS2 everyday but the data is loaded to cube for every 15 days. There is a program that has to be run before loading the data to cube. The program uses two different kinds of calendars X1 and X2(not both at the same time) and each calendar is one month apart. For example if X1 has Aug 1st as date in it, the next date in X1 would be Sept 1st and the X2 has dates in such a way that the date is Aug 15th and the next date in X2 is Sept.15th. So, as the system uses both the calendars, it uploads data to cube every 15 days.
Now I have to make a process chain in such a way that the data gets loaded into the ODS1 and ODS2 eveyday and for every 15 days to the cube using two different calendars. I made a process chain for loading till ods2 and then two different local chains for loading cube. One calendar is given in each start condition. Now I don't know how to integrate the whole chain!
I appreciate anybody's help or advise. ery much.
Thank you v

Hai Aneesh,
            Thanks for the reply. I think we are not in the same page. May be my explcation is not clear. Data is loaded into ODS2 and then a program is run. lets forget the program anyway, it checks for some unwanted records and deletes them. So, soon after my ODS, there are two paths for me, ofcourse both loading the cube but in one path, a program is run and in other the program is not run.Also the start dates of loading are different for these two.If the first part loads data(without running a program) on Aug1st then the second loads data(also runs a program) on 15th to cube.Again the first path has to laod data to cube on 1st of spet.,without running a program and then on 15th sept. the second loads datam with program run. This repeats on and on. I know it very confusing.
               This is what I did. I made a separate processc chain PC1 for loading till ODS(runs daily) and then two different chains, PC2 and PC3(runs for every 15 days) with different start conditions(defined by calendars). PC2 is simply loading data to Cube but PC3 has an additional program in it. Now both PC2 and PC3 donot load at the same time. I have to connect PC1, PC2 and PC3. Can I just make a connection like branches and leave it? so that the loading till ods is done every day but the chain stops at the PC2 and PC3 as the start condition is not satisfied and the PC2 and PC3 run only when their date is reached?
Thank you very much.

Suggestion on process chain

Hai all,
I have a complex issue here. I have a process chain, say PC1- which runs for every 10 days, that has to start based on the success of another process chain, say PC2- that runs daily. Also this PC1 has to start based on a calendar. So I need to have two thing in start condition, one is that it should be dependent on PC2 and PC1 has to start as per a calendar. How can i do this?
Any ideas or advise or document reference is highly appreciated.
Thank youvery much.

I'm sorry, I think I misunderstood your request. PC2 runs every day but you want it to trigger PC1 every 10th day?
If this is the case, then yes, you can put extra scheduling checks in the ABAP program to only raise the event on the 10th day. PC2 will call the ABAP program every day to trigger the event, but you will call the function module BP_EVENT_RAISE only on the 10th day. Your ABAP program will execute, so you will not get an incomplete status in the ABAP process in PC2.
Let me know if this makes sense.

Converting infopackage groups to process chain!

Hi,
We are planning to go for upgradation in near future!
i was asked to convert all infopacakges group schedules to a process chain schedules as infopackage groups are no longer supported in BI 7( ???? i do not why BI 7 would not support Infopacakge groups)
Requirement now is to make process chains out of infopacakge groups
i am little puzzeled of how to model process chain as there are too many infopacakges in groups and there are quite a lot of groups as well
Any tips?
Raj

Hi Raj,
You can still do Info package groups through RSA1OLD. Info package groups are outdated
1) infopackage group you can only schedule infopackages. You would still need to do the other steps manually. Whereas in process chains you can schedule all the steps. In process chains, you can also specify complex rules like, start 6th infopackage only when 1st and 5th have completed.
2) The disadvantage of Infopackage groups is that it is outdated and there won't any new features in them. So let us say that you wanted to implement a data loading logic which can be done by process chains, it might be too late as you would have created a lot of IP Groups by that time. infopackage group..scope is limited to just infopackage..that too they run one-by-one..not in parallel..
infopakge groups if any info package fails we need to trigger all the loads
manualy .where as in Process chains just correct that particular ipak and repeat from that particular process .it will take care abt remaing subsequent chains .
And also we can trigger parallel loads as well in this. Its much user friendly in
monitoring.
Dont worry about modelling . All the related Info Packages will be in one group. You need to see the flow and Design such that have info package and then DTP. and see if many data targets have same data source.then you can have only one infopackage and filtering through many DTP's.

I want to kill a particular process chain from a meta chain..

Hi All,
I want to kill a particular process chain from a meta chain as, its having some technical issues.So what is the procedure.to handle this process..
Thanks..

follow these steps
1.Go to the chain which you want to kill .
2.Go in the log view->top menu bar execution tab.>Remove from schedule.
you are done
Another way (bit complex but will work )
1.Go to the process chain running (which you want to kill) in the log view copy the logid (lef hand side of screen you can get that)
2.Open a new session ,Go to se37 enter function module RSPC_PROCESS_FINISH -->execute it
3.Now again go Log view of the process chain right click on the start variant>display messages>Chain tab
copy the variant ,instance ,date time etc
4.IN execution screen of RSPC_PROCESS_FINISH enter the variant,instance,data time,logid and Type=TRIGGER
status = R.
Actually you will see something like this in input screen
I_LOGID -
>from log view in RSPC
I_CHAIN
I_TYPE   -
>TRIGGER for start variant
I_VARIANT----
>from log view in RSPC
I_INSTANCE------>from log view in RSPC
I_STATE     -
>R
I_EVENTNO                       00
I_HOLD
I_JOB_COUNT
I_BATCHDATE   -
>from log view in RSPC
I_BATCHTIME                     00:00:00
I_DUMP_AT_ERROR
Thats all and your are done.
But I would suggest Remove from Schedule will surely work....If you have any doubts let me know.

How to delete Master data using Process Chain

I need to delete data in respective data targets such as Infocubes, DSOs & Master data Infoobjects. It was fine with Infocubes & DSOs using respective process type. But the issue is with Master data Infoobjects.
Is there any process type by using which I can delete data in Master data Infoobjects using process chain?

Murali,
Master data object process type is not there because in BW, master data is conformed or is shared by other infoproviders. Due to this dependency, master data loading is a bit more complex. You need to drop all the data from all the infproviders which are using the master data you want to delete.
