Hi
Process Chain: A process chain is used to trigger different process (Info Package,Attribute change run,compress request.,activate request(ODS) in a sequence according to requirment
Meta Chain: In a similar way like process chain but used to trigger different process chains in a sequence according to requirment
For more details please see the threads, you will get all the info

Meta Chain Issue

Hi All,
I have some meta chains in the process chain and all of the meta chains are triggered using-
"Start using Meta Chain or API"
Its evident that, once we triggerr the start varinat in the main chain the rest of meta chains get triggered. In our case one particular meta chain is not getting triggered at all. But the rest have gone fine. In the process chain Log view, its staying in yellow for a long time and in SM37, the job is getting cancelled.
the message I got in Log view, at the time the meta chain gets triggered is, "Process chain variant is ZA******** is not scheduled waiting for event RSPROCESS 4A******"
I have tried all the possibilities of "Repeat, Kill the process in SM51"
Can you please advise, the solution for this.
Thanks in advance,
Cheers,

hi,
right click on that meta chain yu will reach the planning view there in change selcetion icon .. you set the setting to immediate and remove the tick for perodic and then schedule it ..
hope this helps you ..

How can I find corresponding meta chain in RSPC

Hello Gurus,
I have a local process chain, how can I find corresponding meta chain in RSPC? and also I have already created a process chain, How can I changed the name of this process chain?
Many thanks,

Hi,
Basically all chains are same, but if you click on Start it will goto Start Process Screen there you can find Scheduling Options, in that Direct Scheduling is selected so it is Main Chain (Meta Chain), if it is Starting using Meta Chain API is selected then it is local chain in that meta chain.
Note: Basicall all Chains are same based on above differnecce you can find it.
By Looking at Chain we can decide it is it Meta chain or Norma Chain, if you open RSPC and then Open any Chain If it is having
Start-->Local , then it is Meta Chain and Local is Norma Chain.
Thanks

Query regarding meta chain in SAP BI

Hi can any body solve the problem on this Meta chain in SAP BI..
There is a meta chain which holds three process chains say N1,N2,N3. in a sequential order.
Now here as soon as the meta chain is triggered the process chain N1 is executed properly and is is in green..but after this the next process chain N2 is not getting triggered..can anybody tell me the reason for that??

check the start parameter of 2nd chain
it should be immediate

Dear Suman,
To initiate the mails we first need to have SMTP connection. To check the same go to so00 and try sending mails to ur ID. If is successful it states that u have the SMTP access.
To create mails to Process chains:
Right Click on the Process varient select the Create Message in the context menu.
Select the type of mail i.e for successful, Error, Anyways.
Then follow the screens.
Note: The recipient type should be Via Internet.
Hope this helps u.

Failed meta chain maintenance in Process chain in SAP BI

Hi all,
I have a Process chain having the meta chain of master data population.When successful , proceeds with the further steps in process chain. It has been scheduled in midnight.
After monitoring the PC , found the error in the master meta chain , so i repeat the step.
Here , after success of meta chain all steps gets running down the line till the end step in PC.
I do not want to re-run the steps below meta chain after repeat step.
Any Ideas to ignore the re-run ??

Hi,
If your Process is still running(Yellow color status) then right click it and go to Schduled Jobs. On this you will go to Job Overview there you can press STOP.
Else go to the SM37, there you can go and select your process using your process ID and STOP it.
And if you want to kill the complete process chain then go for Remove from Schedule.
Different Ways to stop process chain
1)SM37 -->Kill Job
2)SM50/sm66- ->Kill process
3)RSPC>Job Log>Make the process RED forecefully.
4)RSPC>Process chain> main Menu"Remove from Scheduling" OR
5)se37-->RSPC_API_CHAIN_INTERRUPT
give RFC BW system name(technical) and process chain name(technical)
Steps 1 -3 stops the chain running in process
Steps 4-5 stops the chain AFTER the current job which is running is completed as sucessful or Failure by nature.
Hope this helps you.

How to identify the meta chain in which the Process Chain is used

Hi,
   I had a Process Chain which is designed to Load Transaction Data.
   This process chain is scheduled to start as a part of Meta Chain...
   How can i locate that META chain in which this Process Chain is used
Thanks

Hi
There is no where used list for Process chain, but you can check it in table RSPCCHAIN.
Give details as below:
Version is 'A'.
Process Type is 'CHAIN'.
Process Variants = 'enter technical name of the local chain'.
now hit execute button.
You can see the list of process chains under Chain ID column.

<b>Metachain</b>
Steps for Metachain :
1. Start ( In this variant set ur schedule times for this metachain )
2.Local Process Chain 1 ( Say its a master data process chain - Get into the start variant of this chain ( Sub chain - like any other chain ) and check the second radio button " Start using metachain or API " )
3.Local Process Chain 2 ( Say its a transaction data process chain do the same as in step 2 )

Event in meta chain

Hi All,
I have a requirement like ,the last local process chain(L) in the metachain should trigger only after the completion of all local chains above it and the other process chain(A) which is not included in this meta chain.For this I have created a metachain like ,
1.it has 4 local chains in it
2.AND process type
3.Last local chain(L)
In this last local chain(L) ,I have included event(this event is included at the end of the other process chain(A) which is not in this meta chain) in its direct scheduling.
When I tested this process chain,in a way that, first I scheduled the other process chain(A), and the metachain.so the last loacal chain(L) waited for all its above local chains to complete even though the other process chain(A) which has event programme completed first.
But when I tested vice versa, that is,first I scheduled the metachain,then this last loacal chain(L) didn't wait for that the other process chain(A) to complete.
Can you please let me know how to meet this condition using event.
Thanks All

Hi,
As mentioned above, an event is used to trigger the process chain.
Just to give you an example,
Suppose that you dont want your daily process chain to get triggered on saturday.
In that case, you can write a program to check which day of the week it is, and return an event id through the program.
This program can be used in a new process chain, which will execute everyday.
This event id can then be used in the start variant of your process chain, using the option After Event.
Hence, your daily process chain will get triggered only if the Event id returns the day as Sunday to Friday.
It will not get triggered on Saturdays.
Hope this helps....

Local chain, Meta chain, and Remote chain

Hi,
Can any one explain me what exactly is the difference among the process chains?
Meta chain is a process chain that calls the other process chain
Local chain is the PC included in any other Process types?
Cannot differentiate Local and meta chaisn now !
same is the case with remote process chains
Raj

Hi,
Metachain is a process chain, for which you determine this start condition, that is fixed to another process chain. The process chain is started directly by this metachain.If you start the start process using a metachain, it is not scheduled after you have activated the related process chain. The process chain is only started when the metachain, to which it is linked, is running. rocess chains can be scheduled as processes in additional process chains, which are known as meta chains. If the process chain you want to execute is in another system, use the process type Process Chain Remote, called remote process chain in the following. A remote process chain is a local process in the calling system that calls a process chain in this system, using a destination in another system, that is to be executed there. The remote process chain communicates with the other system and synchronously starts the executed process chain. After terminating the process chain in another system, this is reported back to the meta chain in the calling system. sing a remote process chain as the process of a metachain, you can schedule a process chain from another system in a process chain of the calling system.
Using a remote process chain as the process of a metachain, you can schedule a process chain from another system in a process chain of the calling system. In addition to remote process chains, you can also schedule local process chains as processes in a metachain. A local process chain consists of processes that are scheduled in the same system as the metachain. You schedule it as a process in the same system as the metachain.

Transport collection for meta chain

Hi all,
I had a meta chain which carries 4 master chains.
now we made change in the order ( before order 1-2-3-4 changed order 1-3-4-2) of the 4 master chains in the Meta chain.
collected the meta chain and transported to test system but the changes are not reflecting in Test system.
could any one please tell, what are all i need to collect to transport the meta chain with new chains.
regards
sandy

Hi,
You only needed to collect the meta chain and not the other one's, if your transport was successfull then simply goto your target system open the chain in change mode and you will see the changes. Simply activate that chain and it'll be perfect.

Copy process Chain with Meta chain

Hi experts,
how to copy the process chain with Meta chain, since the process chain which I planing to copy it hold meta chain and also local chain, I coping for change the technical name for the PC, is it possible to copy meta chain and local chain along with PC?
and plz breif me about meta chain and local chain why we have to use them and where we have to use them?
plz explain with scenario.
Thanks,

Hi,
Once after the copy of the chains you need to change the start variant with the new one as the same start process can not be used in two process chains at the same time.
So Once after changing the start process for your MC and LC then you are good to go ahead to trigger the same.
If you trigger the MC then it will take care of trigerring the LC automatically.
In terms of changes in the process chain, you can get the last changed details in the log view but you can track the timestamp of changes from the process chain tables like (RSPC* and then press F4). But you can not track which process has been changed in this.
Thanks

Local Chain Multiple times in a Meta Chain

Hi,
I have a scenario in which I have to call the same local chain multiple times in a Meta Chain.
The system is not allowing me to add the same local chain in my meta chain more than two times.
System is throwing the below message:
Diagnosis
The link that you made between process CHAIN ZREBATE_LOAD and process CHAIN ZREBATE_LOAD is a reverse connection, because process CHAIN ZREBATE_LOAD already precedes CHAIN ZREBATE_LOAD in the chain.
System response
This kind of connection is not supported.
Procedure
Schedule a copy of process CHAIN ZREBATE_LOAD behind CHAIN ZREBATE_LOAD.
Can anyone tell if there is a way to call the same local chain multiple times in a meta chain WITHOUT making a copy of the local Chain?
I understand that if I make a copy of my local chain it will allow me to add it multiple times in the meta chain.
Useful tips will be awarded by points.
Thanks,
AT

Hi Siggi,
I did not know that promising points is against the rules..Sorry about that.
It is just that I see every other thread has that line at the bottom (unfortunately never saw anyone get a bashing on that)....will keep it in mind.
Well, coming to what I am trying to achieve...here is the scenario:
I have a chain where a table is being read and the data gets loaded for the quarter date in that table (table has quarter dates in it e.g.: 01012007 to 03312007). At one point the table has ONLY one entry for one quarter.
Now, the requirement is to load data data for two years (i.e. 8 quarters).
In order to automate, I have written a small program to update that table with the dates of next quarter. I have added this program as the last step in my chain.
Now, I have created a meta chain in which I want to call my local chain (8 times) so that all the quarters get loaded automaticaly.
I am able to call my local chain 2 times in the meta chain and it works exactly the way I want it to run. However, system is not letting me add my local chain more than 2 times.
I am getting the message that I mentioned in my thread.
I understand that if I make 8 copies of my local chain, the system will allow me to add those 8 chains in my meta chain.
My question is if there is a way to add a local chain multiple times (say 8 times) in the same meta chain WITHOUT making copies of the local chain.
Thanks very much.

I have one meta chain.that meta chain have 5 local chains 2 local is failed

Dear All,
i have one meta chain.that meta chain have 5 local chains 2 local is failed in the mddle. 3,4,5 chains were went successful.i knoe the solution hoe to correct. i want to execute rest of process of the second chain only. i dont want to 3rd , 4th and Fifth. i can not do Manully for evry process chain in the second chain because second local chain is very big chain. i can not do repeat also .suppose if i go for repeat again 3rd , 4th ,5 thsteps will be execut.
hoe can i solve this issue.please guide me.

Hi
Right click on the green block, from where the next block is not triggering. Take the variant and instance value.
Goto table RSPCPROCESSLOG and give the variant and instance value as input. Check the state field value. It should be G (i.e. successfully completed) then only next block will be triggered.
If you want to start next block manually, goto function module RSPC_PROCESS_FINISH, give i_logid, i_type, i_variant and i_instance values from RSPCPROCESSLOG table and enter i_state value as G.
After executing the function module, next block of the process chain will automatically start.

How to check the parent process chain of a meta chain

Hello Friends,
Recently I joined a new project, which is of environment BW 3.0. I am trying to find the dependent process chain's parent, but could'nt able to find them. I went through all the process chains manually to check whther the dependent process chain is mentioned in them, but could'nt find any......
Can any of you help me to know how to find the parent process chain of a meta chain ?
I really appreciate your time, will be awarding points to any answers.......
Thanks,

Hello Radhan,
thanks for your quick reply. I searched the table based on your advice, but i could'nt get the parent process chain's name. Can you throw some more ideas please..........
Thanks,
