Small qn in Process Chain

Dear Guru's
I need a small Clarification regarding Pchains..
Suppose i have a process chain in which i have to add a process ''Delete PSA Request'' in this process if i keep 50 PSA's object name, Then will all these PSA data gets deleted parallelly or one after the other.
Thanks and Regards,
Dev

Hi Srinivas,
For every process type in your Process chain 1 job is created,so if you include 50 PSA Object names in one process type then there will be one job for the deletion of all.
I don't think you can create different jobs for 50 PSA deletions in one process type.

Small issue in Process Chain

Hi Dudes,
I have small problem in Process chain.
1)Start
2)Load :
3)activate : Always
when i ran my PC ,due to some problem my Load Process type got fail.
But after that i have actiavte Process type(PT) which should run whether Load PT is in success or fails .
But it got stuck due to message "Status Change of Process LOADING ZPAK_EFAJ6WFZPJPA7MWVSZXETN4PE.
Save Status and Trigger Events if Appropriate"
with two option yes and no.
when i click on yes then only it goes .
But if i would run and nobody around then i would gets stuck at that point only .
Is there any solution for that !!
Hope i m clear toexplain u my problem
every person will get the point

I do understand what u r saying.
But I have given an example. Why that message box comes.
Cant we suppress automatically?
Suppose had I been have a process type which send a mails after load status whether it fails or success at that point this could be an issue ??.
So if it would be stuck like this then it could not send a mail.
Hope u have understood my problem .
or if u want in detail give me ur id i send u screen shot

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,

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.

Process chain and Control M

Hi Gurus
We are designing process chain for our BW solution.
We have identified the dependancies of various loads which includes flat file loads and loads from R/3.
Now we would like to control ERP and BW jobs by Control M .
I have the following questions:
1. Which portion of BW process chain do we need to plug in to Control M. ? Do we need to connect the Meta chain to control M or different process chains to Control M?
2.When we create Process chain for BW, what is the best practice? Is it good to create small chains and connect them via Meta chain? or we have to create small chains only?
3. Can we include R/3 extraction Jobs and V3 Jobs in our BW process chain? so that they will trigger when we run the process chain?
4. If we decide to run V 3 jobs after every half an hour on R3 side then how often we have to extract data to BW? and how to catch correct delta without missing single record?
I would appreciate if you can help me with your knowledge.
Thanks
Kris

Hi Kris,
Control M is a third party scheduling tool provided by BMC software.
1) You have option to either include a meta chain or individual chains in Control M .
2) It depends on how your data is extracted. If you have any dependecy jobs on sourcre system, then it is better to create small process chians and include them along with your dependecy jobs in Control M
3)you can include R/3 dependency jobs and V3 jobs in Control M. Once those jobs are finished you can run BW process chains via Control M.
4)You have several scheduling options availalbe in control M to take care of your BW and R/3 jobs.
V3 jobs collect data from R/3 application tables and fill R/3 delta queue(RSA7). when you run BW process chain it will collect all the data available from R/3 delta queue.
If both jobs are running at same time, then it is better to apply some wait time on BW jobs(in process chians).
hope this helps

Process chain running long time

Hi all..
I have one process chain.that chain haveing very small data.when iam created time it runs nearly 20 to 30 mints.
Now the same chain running nearly 3 hours..
Why its taking very long time?How to reduce the chain running time.Any steps to reduce the chain running time..
Thanks
Ramya

Hi,
Check the load in the chain which is taking long time.
Check out how much data is that load uploading.

Runtime error during opening a process chain in rspcm

Hello,
i created a process chain just a simple one which loads Data from the DataSource into a DSO and then into a InfoCube.
I executed this processchain without activiating my Initial-Request in the DSO.
So i got a hanging Request there, i deleted all Requests from all objects in this processchain. Still had this hanging Request, so i deleted this one Request from the RSEQDONE. Now my processchain is working, but it takes very long to open it when i am in the RSPCM or i even get a runtime error.
Any suggestions?

Regarding RSPCM you better to check the oss notes which are shared by Michael devine.
Coming to your issue, if you have loading huge data then better to increase your wait time of your info pack load.
go to your info pack --> menu scheduler-->Time out time, increase as you need.
if your doing full loads, please use proper selections and split your load as small chunks.
increase packet sizes and parallel settings to speed up your load.

Index in process chain question

Hi Experts,
I am creating a process chain with only 1 infopackage, do i need to add a "delete index" and "create index" variant in this chain or do i NOT need to do this because it is only one infopackage? Your advise is appreciated. Thanks in advance.

Also note that if the number of data records to be loaded is small as compared to the total number of records already in the cube, then deleting and recreating (would affect load perf) but would take more time and resources than loading in the presence of these index.
If you like, search for some posts by Pizzaman...you will get a very good understanding of this topic.
Hope this helps...

ABAP program to add in the process chain before the attribute change run

Hi
I need a ABAP program to add in the process chain before the attribute change run(process) to avoid the locks, can any one send me the program
Regards,
Satish

I am not sure of any standard program .... but you can write your own... should be a small one..
you can check if the table RSDMDENQ has entry for your InfoObject... if yes, then its locked.. if not.. its not locked

Parallel processing for ABAP prorams in Process chain.

Hi All,
In one of the process chain, we have added the ABAP program. In Backend,the job is running as "BI_PROCESS_ABAP".
I just want to know, same like DTP, can we keep parallel processing for the ABAP programs also. Please suggest.
Thanks.

Hello Jalina
Also check with BASIS if the memory allocated to run this program has not overflowed and the selections you have in your ABAP program is in small chunks and use variants to run them in parallel OR series
Thanks

R3 job completion trigger a process chain to run on BW

Hello,
I was wondering how I can trigger a process chain to run on BW 3.5 after a SM37 job completes on R3?
I have been searching the forums and the web, but I haven't found what I am looking for.
Thanks,
Nick

Hello Pramod,
I would need a more detailed suggestion to implement, but thanks for starting the discussion.
I thought it would be as easy as this
1. Create an event in BW
2. Have a process chain that starts when that event is raised.
Having implemented and successfully tested steps 1 and 2, the rest should be simple (I was able to raise the event on BW locally and the chain did run as expected)
3. On R3, create a small ABAP program that calls the BP_EVENT_RAISED Function Module on R3.
4. Pass that Function Module the following parameters
A. My BW system name, and
B. The event name that I created on my BW system
5. Add that ABAP program to the end of the job on R3.
It doesn't work though! The event i created on BW, doesn't seem to exist from R3's perspective. I was hoping it was as easy as that. Hopefully I am missing something simple, but so far R3 does not want to cause the event on BW to be raised.
Thanks,
Nick

Problem in process chain running for 3 days

Hi Experts,
Please help me
We have process chain like below
1.     delete index
2.     full loads going 3 cubes (16 infopacs)
3.     loading to ods and then update to cube
4.     delete overlapping requests (16 infopac)
5.     create index
6.     aggregate filling
7.     delete PSA
Now the issue is, from last Saturday onwards
Process chains was still in Yellow status till date, so now, 1,2,3,4, are still running
In process chains, out if 16 infopacs, 12 are green, remaining 4 are stopped
And in ODS activation of ods data variant shows yellow, but when checked the data is activated, but not pushed to cube. When checked log it show u201Csystem exception error_messageu201D, so process terminated.
When we checked for shortdump,
It says u201Clocal time on the application server is incorrectu201D
Experts please let me know how to solve this and correct the load.

Hi Experts,
Thank u for your help,
I have done the steps manually yestarday, checked todays, still it is in yellow status.
let me explain the scenario,
The data is going to 3 cubes,
the process chain is designed like this,
1. initially delete index
2. full load to cube using 16 infopac and loading from (2)ODS to cube.
3. delete overlapping requests
4. create index (3 cubes)
5. fill aggregates (only one cube)
6. Delete PSA request
so now , chain is having problem at
1. data is loaded to ods
2. data activation (showing yellow, but when checked data is activated)
3. further update to cube (2 cubes) in process chain this is not started atall ( so y'day I've done manually)
4. out 16 infocpack, only 12 infopacs are green and remaining 4 are not started.
so yestarday I've manually schedule remaining 4 infopacs.
and deleted previour requests in infocube as they are full load, but I did'nt done create index and fill aggregate steps.
now the problem is , out of 3 cube report available request is present for 2 cubes, but for 3 cube this report request is not available, but QM status is green
please let me know how to proceed.
one small silly question, do i need to fill aggregate step to get this report available request.....please suggest.
Thanks & Regards,
Raghu

Decision Step in Process chain

Hello All,
I have a meta chain which run at 00:30 midnight everyday.
It consist of 4 sub process chain.
The last process chain consist of decision step in it.
This last process chain should run only at first friday of every month.
For this reason this decision step is included in it.
It consist of the following formula.
"( ( Local Time > '17:00:00' ) AND ( DATE_WEEKDAY1( Local date + 1 ) = '6' ) AND ( RIGHT( 2, ( Local date + 1 ) ) <= '07' ) ) OR ( ( Local Time <= '17:00:00' ) AND ( DATE_WEEKDAY1( Local date ) = '6' ) AND ( RIGHT( 2, ( Local date ) ) <= '07' ) )"
Till now the process chain had never executed at 1st friday of every month.
The third sub process chain finishes at 3:30 everyday. So due to that the local time of starting the 4th process will be 3:32 and then this decison checks.
The first condition fails as the local time is <17:00:00 and not > 17:00:00.
Hence it will move to the other OR condition.
But friday is weekday '05' and not as '06' hence again the second condition is failing. Hence the process chain is not executed at first friday.
After doing this small change also what further more changes should be done in the formula which will help me to execute that chain only at first friday of every month and for rest day it should not execute.
Points will be assigned for helpful answere.

The decision step is fine and making changes in the formulae would be ideal but another alternative is through restrictions in the start step for the 4th process chain w.r.t the calenday you will choose. You can restrict it to a particular day for the month with marking only 1st Friday for every month as workday

Can we call Function Module from Process Chain?

Hello experts,
I have a small question.
Can we call Function Module(SE37) from Process Chain?
If yes can you please provide some example link?
I m new to BI world.
regards

Hi,
Create one ABAP program and call the function module from that program. Check the link to know how to call a function module from an ABAP program.
http://help.sap.com/saphelp_wp/helpdata/en/d1/801edb454211d189710000e8322d00/content.htm
http://help.sap.com/saphelp_wp/helpdata/en/9f/db98ef35c111d1829f0000e829fbfe/content.htm
Then use process type "ABAP Program" in your process chain and add the program you have created. So then this program will be executed via process chain and this program will call the function module.

Process chain design/schedule/monitoring/debugging

hi friends
pls help me on the issue of process chain design/schedule/monitoring/debugging
with one of real time scenario, with help of t-codes and detail navigation
thanks in advance
venkatp

I have listed below the major informatin neede for your requirement...
1.Go to RSPC to view all the chains.
2.There click on any chain which you want to run/view.
3.Click on the log view(shift+F1) to view all the previous runs of the chain and whether they have failed or successful(here you can select 1 day,week ,month etc in the display range)
4.If you want to modify the chain /add a process type /change the variant then click (Ctrl+F9) and do the changes.
Even you can change the start variant in change mode for manual scheduling>right click on start process typeselect display variant--now select start Direct Scheduling/ API or Metachain
under direct scheuling option you can trigger it by setting start immediately /Date-time/After job/event whatever you want to do
Else you can make it part of a Metachain consisting of different such small local process chains.
Now Click on Schedule (F8) to run this chain manually.
5.For Monitoring use Tcodes SM37/RSPCM/SM50
Also you can use BWCCMS.
I usually prefer sm37 to view all the background jobs but SM50 is also useful.
6.debug loop can be used to debug a process chain.(you have to specify here the gap between one event been triggered and the next subsequent process starting)
to capture process in debugger go to SM37(job overview) or to SM50(process overview)

Adding infopackage in Process chain

Hi All,
         i am creating processing chain and i am trying to add a infopackage to that.
         but when i press F4 or small square box it is saying there are no infopackage but i have some infopackages created in Datasource.
      while i tried to add DTP it was successful but not able to add infopackages to process chain,
      the process chain is still unassigned is this any thing to deal with this.
      Please hlep me out and i have gone through the blogs in sdn for this but i was not able to figure it out.
Thanks in advance..
Srinivas.

Hi,
if you are displaying in tree format, then you may not be able to find the process chain.(
I do not know the reason, but i had the same issue in past, as i remember. but i solved it)
Please switch to network display in process chain and try again.
In process chain, go to infosource and with crtrl+f searchh the technical name of the infopackage.
Let me know if it helps
Regards
Derya
