Reg - Process chain

Hello Gurus,
I am working in Process chain and I am new to this.
I am having some basic doubts.Can any one of them,clarify my doubts.
1.Whats the difference between event and job.
2.How,we can find out the particular chain is a meta chain or local chain.
3.Incase,If the chain is failed,how we can start the process.whats the step.
4.Where,we can findout the process chain status..(i.e,its successfully running or unsucessfull. like this)..any transaction code is there to know the status
5.Tell me,what are the things,i shouldnt do.(as a precautionary steps)
Thanks in advance and It will be great help,if somebody clarify my doubts and forward docs to my email id...if u r having any realtime doc.
I will assign points.

hi,
1. an event can trigger a job. After a job has finished, an event is raised and a new job is triggered (or not)
2. check for the starter. locla chains have the option "strated by other chain" an can only be started directly whe having changed the starter.
3. depends: in NW2004 process the chain manually or restert the chain completely. only few processtypes are able to be repaired. to recall the setting where the chain crashed is not possible (with the standard types ...)
In NW2004s with BW7.0 its possible to start a chain from where it failed.
4. you have 3 views for process chains in rspc: create, check and protocol (this paperlike button) here you can see the protocols for your chain. even when it has been activated, if it runs etc. you can also go to trc SLG1 to look for ProcessChain protocols.
5.
Transportiation fails in most cases. allow maintenance in
Production.
Never set a processchain live, untested. Especially monitor the number of processes allocated.
(only basic rules)

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.

Reg. process chains

Hi
Will any one send step by step to do process chain. I am getting stuck in middle.
Please help.
Thanks.
regards
Sridhar
[email protected]

Hi Sridhar,
What exactly you mean by saying "to do process chain". If you want to know the steps to create a process chain, here are the guidelines:
In the BW Administrator Workbench:
 1. Choose the Process Chain Maintenance icon from the AWB toolbar.
The Process Chain Selection dialog box appears.
 2. Choose Create.
 3. Enter the technical name and a description of the chain, and confirm your entry.
The Add Start Process dialog box appears.
 4. Create a variant for a start process.
 a.On the Maintain Start Process screen, choose whether you want to schedule the chain directly or whether you want to start it using a metachain.
 b. If you choose to schedule the chain directly, enter the start date value for the chain under Change Selections and save your entries.
The Maintain Start Process screen appears again.
 c. Save your entries, go back to the previous screen and confirm your entries in the Add Start Process dialog box.
The Plan View of the process chain maintenance screen appears.
In the left-hand area of the screen, a navigation area is displayed. In the right-hand area of the screen, the process chain is displayed.
Note: If the process that you used to create a chain is linked to additional processes by default, the respective process variants are generated and inserted into the process chain automatically. These variants are suggestions and can be changed, replaced or removed from the chain as required. Variant maintenance is called when the change run performs automatic insert.
You can turn this system response off using Settings Default Chains.
5. Use Drag&Drop or a double-click to insert any additional relevant processes into your process chain.
Choose Process Types to select the processes. This sorts the process types according to different categories. You can also call up InfoPackages and processes for the data target from the separate InfoSources and Data Targets navigation trees.
6. When you add a process, you need to select a process variant or create a new variant. For collection processes, the system uniquely determines the variants
Various functions for editing the process are available from the context menu:
7. Hold down the left mouse button to connect the processes with events.
Note: Before you do this, select the process underneath the process type row, and position the cursor over the required process. When you select the process type row, the whole process is moved into the plan view.
From the context menu of a link, you can display the event or remove the link. To do this, select the link and right-click with the mouse.
8. If necessary, specify whether you want the event to be triggered after the previous process has been completed successfully or unsuccessfully, or whether you want the event to be triggered independently of the outcome of the process that precedes it. If the process that triggers the event has more than one option, choose the option after which the successor process is to be run
 9. Assign a display component to the process chain using Attributes -> Display Components.
 10. Maintain additional process chain attributes if necessary.
 11. Check your process chain in the Check View and make any necessary corrections.
Note:The Legend explains the meaning of the different colors used to display the processes and links.
From the context menu for a process, you can display the messages resulting from the check.
During the check, the system calculates the number of parallel processes according to the structure of the chain (subchains are recursively taken into account here). The result is compared with the number of background processes on the chosen server (or the total of all available servers if no server is specified in the attributes of the process chain). If the number of parallel processes is greater than the number of available background processes, the system highlights every level of the process chain where the number of processes is too high. The system produces a warning for these levels.
12. Save your process chain if it does not contain any errors.
Result:
You can activate and schedule your process chain. After scheduling, the chain starts in accordance with the start process selections. For example, if you scheduled the start process directly and chose Immediately as the start date value, the chain run starts immediately after scheduling. In the Log View, you can display the reports for the chain runs.

Reg Process chain scheduling.

Hi.
Here is a situation: I have a process chain named Process chain1 . Which will run on weekly basis. Now i wanted to run this procss chain in every month 5 th working day. I will create new chain as process chain2 and i will add my Process chain1 as local process chain.
My question is :
Is it possible to use Process chain1 for individual run on weekly basis and as a local process in Process chain2 for the 5 th working day run?
But for any start variant there are only 2 options
1) Direct scheduling
2) start using meta chain
What I shd to in this situation
Thanks,
Harish

Hi Harish,
Yes it is possible without creating a new process chain.
Schedule it to rum every week. If it is already have done get the exact job name which is scheduled (you can can get this by right click on start variant and display scheduled jobs).
Copy this job and schedule it as you wanted to run monthly on 5th.
Hope this helps,

Reg:process chains could be started manually and automatically

Hi
Each process chain could be started manually and automatically
>If i want to start the process chain manually, how should i start and what are the settings shall i mark
>If i want to start the process chain automatically, is there any tool are there to start the process chain at that particular time
Plz clarify my doughts it is use full too me
Thanks & Regards
manikanta

Hello,
PC can be started both manually and automatically.
Every PC has a start variant, when you right click on the start variant and go in the edit option, select the option direct scheduling. Then in change selection, check the box immediate and keep the periodic job at the bottom unchecked.
Hit the tick, save on the other screen. And when back on the PC screen, from the menu option select the schedule option.
This will run the chain manually.
To run it automatically, follow the same procedure but instead of using immediate choose, data and time, provide date and time when you want to run, you can check periodic option if you want the chain to run daily, weekly or monthly.

Inf reg process chains design

Hi All,
My process chain is done succesfully.. I followed as
Main Chain
Start->Delete Data (3ods)->Load data(3ods)->Activate(3ods)-> And(all success ful)->2local process chains(series to and) -> Materdata Load(parallel to and)->Attribute change run
Local Process chain 1: ( Data loads from ods to cube)
Start->delete index(cube)-> load data(6 info packages)
Local Process Chain 2: (Data loads from Flat File to Cube)
Start->load Data(another 6 Info Packages)->and(condition)-> delete Index(cube).
Now tell me in design why am getting too many parallel processes for chosen sever
MSg NO:RSPC118
why these warnings are comming? give some light on this
regards
ashwin

Hi ashwin,
Too many parallel processes for chosen server
Message no. RSPC118
Diagnosis
On the server you have chosen, there are only 4 batch processes available. The process chain has been designed in such as way that 5 processes must be processed parallel.
System Response
Only 4 processes can be processed parallel. Note also that to be able to start sub-chains, AT LEAST TWO free batch processes must be available. Otherwise a lock situation may arise.
For more information, see SAP Note 621400.
Procedure
Reduce the number of parallel processes in the chain or include sub- chains. This warning applies to all relevant processes.
Procedure for System Administration
Increase the number of batch processes available. You should note however that it makes no sense to set up more batch processes than there are CPUs on server .
Suggestions:
You may created your Process Chain with 5 parrllel lines or more..You don't free Background Process Available in the server where it is running. I think you have only 4 Background Process Available.
code
Start Variant
Variant 1 Variant 2 Variant 3 Variant 4 Variant 5
Variant6 variant 7 Variant 8 Variant 9 variant 10
You can replace it as..
Code
Start Variant
Variant 1 Variant 2
Variant3 Variant 4
Variant 5 Variant6
variant 7 Variant 8
Variant 9 variant 10
do's:
1.You can change your Process Chain Model
2.You can increase background Process on your System.
3.You can keep it like this if you are working Development. Your Production will have Extra processes.

Reg. Error while Full load - process chain

Hi,
I am running a process chain, which is a full load. In Manage screen it is in RED status whereas, While i chekced in Monitor screen it is showing as "Missing messages" . While I checked in the error and warning messages, I found that the data packet should be run manually. So I tried Manual update option by killing the job manually. After doing this i tried to run the same process with "Back to Technical Status" option. While performin this again i got an error saying "REQUXXXX terminated, as data packet 0000XX could not be locked"
How this error can be rectified.
Please advice.
Thanks in advance!!!

Hi Melissa.....
While i chekced in Monitor screen it is showing as "Missing messages"........where did u got the message.............in the data packet.......right...........?..........
I found that the data packet should be run manually. So I tried Manual update option by killing the job manually..................which job u hav killed........? Extraction Job?If u hav killed the Extraction job........then Manual update is not possible..............Manual update is only possible when the Extraction job will get completed successfully........
Due to this u r getting the Error Message error saying "REQUXXXX terminated, as data packet 0000XX could not be locked"....................When the request itself does'nt exist............how could u do Manual update for that deletedrequuest........
Then only option is..............make the QM status red.............delete the request from the target and repeat the load.........
Hope this helps.......

Reg : To view process chain flow for a cube

HI Experts,
I need to view process chain flow for a particular cube of sales distribution.Can you please tell me stps to perform .

Hi,
If the cube is already loaded then you can just to the infopackages which are loading it and in the infopackages you have option in the "schedule" tab to see which process chain it is loading.
if not then you will have to identify which data source is loading to the cube and check for the infopackge.
and I think the DTP will be in the same chain as well.
For DTP it is alreday mentioned by the others.
Thanks

Reg: Excluding one day from the daily schedule process chain

Hi All,
I have a process chain scheduled daily except Sunday i.e. from Monday to Saturday. Now i want to exclude Saturday from the daily scheduling.
Any idea how we can do that. Early response will be highly appreciated.
Best regards

Hi,
Restrict chain Scheduling on Sundays/Holidays
Create a factory calender using TCode SCAL or ask your basis team to create one.
In this calender mark all days except the day you dont want the chain to run as workday.
Now while scheduling the process chain make use of this calender and restrict it to run only on the workdays.
There is a setting in the start process of the PC by which your chain wont run in sundays/holidays based on calendar or run only on workdays as defined in the factory calendar.
Go to PC > start process > change selection > Date/time. Here enter the date from which the chain should be scheduled and then click the Restrictions button at the bottom. There u can check the option "Dont execute job on sundays or holidays.
Hope this helps.

Reg delta in process chains

Hi,
I'm doing a flat file extraction. The data flow is from Flat file to ODS and then to cube. I need to create a process chain to automate the process.
As per my understanding, the load from a flat file to the ODS is always Full update. Am I right?
The first load we are planning to do a Full upload manually, after which we plan to automate the process using process chains.
Please provide me with inputs on the steps to create a delta from the ODS to the cube.
Thanks.
Darius.

Hi,
Welcome to SDN.
You can autmate the process by having the flat file in the appl server. Flat file data source supports delta as well which is also called Pseudo delta.
If you wish to load your flat file in full update you can still load deltas to cube from ODS.
For this, run a inititliazation w/o data transfer from ODS to Cube and then create a delta IP from ODS to cube.
While creating a process chain, follow this procedure
Start> Load info package ( flat file)> Activate ODS--> Delta IP to Infocube.
hope this helps

Edited by: sirisha gupta on Dec 29, 2008 10:16 AM

hello,
firstly see if the DSO and the transfomration, DTP are all active.
or
This can be due to the incorrect data record in ods
find that record in PSA correct that one and then try to run the load fro PSA to Data target.
or
Uncheck "SID's Generation upon activation" in DSO's settings.
or
you can also try by changing the "Parallel Processing" to "Serial Processing".
In the maintenance screen of DSO, select "Requests" tab:
Click on the "Activate" button at the bottom
Click on the "Activate in Parallel" button
Change the "Number of Processes" to "1" for Serial Processing
Save the setting
You should see the "Activate in Parallel" button with a cross icon now.
Check SAP Notes: 1118205 & 947481
