Connecting two BW systems

Hi guys,
I need at the moment to connect another BW system to ours. The Data should be extract everyday from our BW to the secound one.
At the moment I have 2 points in my mind:
- RFC User
- Datasources
Is there any other things that I have to keep in mind?
Do you know maybe any "how to paper..." to this topic?
Best Regards
Erwin

Hi Erwin,
You can Access to one Particular Cube and provide access to only limited data by Authorization relevant fields.
You can define all these settings in PFCG t-code.
Create role and assign particular Users.
You can use tabs like Menu/Authorizations/User to configure above settings.
You can just get into PFCG t-code in your first BW system and see What kind of settings are there in the system?
Regards,
Suman

Connecting two BW systems to the one R/3 source system

Hi all!
I have to connect two BW Systems to one R3 system. In our last tests we have had problems trying to connect two BW servers simultaneously with R/3 source system because it allows only a logical system name for each R/3 client, and (We guess that we need to define tow diferent logical system name, one for each connection). This has been generating errors when we try to load data from R/3 to BW because, we guess, R/3 does not recognize the BW source system in the ALE connection for someone BW systems at transfer data. In this moment I have one connection active (BW1-R3). The BW2-R3 connection is already inactive. Does anybody know how perform this? we need solve the transfers problem as soon as possible.
Thanks! Judi

Ah...
please don't post twice the same question...in these forums we are always the same !!!
You can close this thread to avoid to look in two different posts...

When we connect two bw systems to one R/3 system?

Hi ,
When we connect two bw systems to one R/3 system,
could you please exlain what is the imact to SAP and BW in terms of query performance, batch performance,Develoment ,Quality system,security,BW Support.
Thanks in advance.

you can connect multiple BW to single R3 source system.
In the delta queue (RSA7 in source system), you have a field with the target system, so you don´t have problem if you have many target bw system, because the data selection is done by system field.
Challenge arises when you have multiple R3 feeding to single BW system and then you have to consolidate the master data say 0material fed from different source system R3 then you can consolidate data using consolidated infoobject.
The following components concatenate to the key of a consolidated InfoObject:
1)source system ID (two-character source system ID; permitted values are stored NW BI table RSSOURSYSTEM)
2)one blank character
3)backend object type (four-character backend object type; permitted values are stored BI table RSBWBEOTYP)
4)master data key value as stored in the source system
Note that the key of a consolidated InfoObject solely consists of non-integrated informations from the different source systems. Integration across source systems results from a (maybee repeatedly applied) data consolidation and cleasing process which unveils duplicate master data keys.
Hope it Helps

Can a R3 system connect two XI system?

Hi,gurus:
Can a R3 system connect two XI system?In SM59 we have to point the rfc to a single xi.Is it right?

If my scenario is about idoc,we can define two RFC in SM59,
and two partners in WE21 and two ports in WE20,right?
Correct..
If my scenario is about abap proxy,then we can define two RFC in SM59,
and two parameters in sxmb_adm in the R3 side,right?Then in the tcode:SPROXY,
we can see both interfaces in two XI systems,right?
this is not posssible...

Connect two ECC systems with one SAP CRM 7.0

Hi Gurus!
I have to do a customizing for connect two ECC 6.0 and one SAP CRM 7.0, only I need the organizational structure from both systems and they need update when the structure from CRM has changes. The business partner goes to ECCs system by PI interfaces.
Both organization models are different, so I have to maintain and update depending the changes in the business.
But I don't know if this is possible, I don't know if we can do this by Middleware, ALE or PI.
Can you please, give your oppinion about this topic?
Best regards,
Eugenia.-

Hi Eugenia,
Please see note 1084315 which descriibes the the multiple backend scenario.
This should be relevant here.

Connecting two BW systems to 4.6 C OLTP SYSTEM

hello experts,
i got issue while creating source system in BW SYSTEM.
My is i trying to conect single oltp source system(4.6C) to TWO BW clients
one system is having connection already... now i am trying to connect other system.
all the RFC Conections looks fine from the both the systems..
here the problem is i am getting error saying source system cannot to created.
as error occured in the oltp system... when i cheked in R3. THERE IS SHORT DUMP.
.....can pls help on ythis process... what steps do i need to follow
other issue.
same rfc connection between CRM AND BI client.
when i try to create crm source in bi...all rfc connetions are fine
i am getting error is source does not exist.
this is minor issue
i want help on the FIRST ONE.. THAT IS REALLY IMPORTANT
THANKS
NAG

Hi Roberto,
Thaks for your quick answer! that is usefull for configuring the system after the connection! but, I need that the connection work properly first. itsn't the case. We connect the both systems to R3 and defined the background user's for connection, but at moment to transfer data the process is not initiated in R3 (back job) for the BW2-R3 link. But for BW1-R3 does. then, we had changed the BW1-R3 link by changed the logical system name in R3, for connect BW2-R3 and this is working correctly. It is the problem: parallel simultaneous load is not working... do you any idea about this? which task we need perform... or some suggestions? thanks!

Connect two BW systems to one source system

Hi Experts!
I would like to know if I can set up two BW systems connect to one source system. We copied and built new BW system (BW2) from existing BW system (BW1). We need to have both system connect to one source system. When I execut Restore from BW2 - RSA1 - Source System, I'm getting a following prompt:
"Connection cannot be used. The connection BB is used in the DEV400 source system as a connection BW1400 to BW. Do you want to delete this connection in source system".
If I select "Delete" then it replace exising connection between BW1 - DEV and creates new connection BW2 - DEV. If I go back to BW1 and do restore then same thing happens as BW2 connection removed.
Is there anyway we can set up two BW systems connection to one source system with restore? Connection works fine since each one can connection with no issues. Just when I do restore, it removes other connection.
Thanks.

Connecting two SCL systems to one backend

Hi,
Is it possible to maintain 2 SCL system connections to one ECC system? We have already connected one SCL system to ECC as a backend and now we want to connect second one. Is it possible to do that?
If yes how to maintain Logical Ports call parameters for that?
Thanks
Domas

Hi Domas,
As pointed our by Holger, this is supported for inbound flows where your use case is to read (pull) some information from SAP into SharePoint. But use cases like reporting and workflow which publishes some items in SharePoint you cannot have the same ECC system.
But if you intention is only for DEV landscape setup and want to save a VM image and still want to support reporting & WF scenarios, then you could also create a new client which is the copy of your existing clients in the same ECC system.
Since logical port configurations are client specific you could practically connect same ECC system (but 2 diff clients) to 2 gateway systems.
Thanks,
Girimurugan

How to connect two BW systems to one ECC system?!?

Hi Experts!
We want to connect our ECC system (P11) to multiple SAP BW systems. Therefore we made a system copy of our productive BW System (P81) and create a new second BW System (T81). When I want to restore to connection to the P11 in the T81, Iu2019ll get the following error message:
u201CDie Verbindung CA wird im Quellsystem P11_001 als Verbindung zum BW T81CLNT001 genutzt.
Soll diese Verbindung im Quellsystem gelöscht werden? Nach erfolgreicher Löschung wird der Anschluss wiederholt.u201C
In English this message means something like that: u201EThe connection CA is used as a connection to the BW T81CLNT001 in the source system. Should this connection be deleted in the source system? This connection can be repeated after successful deletion.u201D
Now I ask myself: How can I connect our new BW System to our ECC System, without destroying the old connection to our productive BW system?!?
Have anyone of you an idea how we can handle this issue?
Thanks in advance!
Regards, Alex

Hi
This happens because of RFC settings duplication as your new BW system is copied from Old one.
First you restore the Production system connection by deleting the existing RFC. But this will delete the new connection you have created ( that is what your dialog message is saying)
Basically , before creating new connection you need to delete some table entries manually , then you can connect both the system to your same source system
Please find the link below where I mentioned the table names from where you need to delete duplicate entries manually.

Connecting two R3 systems to BW

Current State:
We currently have two R3 test systems defined as source systems to our BW test system. All the infosources, infopackages and process chains are connected to only one of those R3 test systems.
Desired State:
What I want to do is "copy" all these definitions to the second test system creating a parallel set of Infopackages and Process chains that pull from the second test system.
Is this possible to do via an SAP supplied program or do I have to do each one manually?

Hi:
Create a new Entry for the new R/3 System in BW QAS:
RSA1
Tools
Mapping of Source System ID
DELETE the OLD Mapping that you already have with Old R/3 System.
Now,
1) COLLECT all the InfoSOurces including Infopackages that you need and Transport them in QAS. If you chose this step, make sure yuo tell BASIS not to move them to PROD.
2) Re-IMPORT some of your old Requests that have those InfoSource/Data SOurce. This may not work because you likely mixed up your transports. Then, I would go with Option-1.
When you complete this step, you will have duplicated all you old R/3 Data SOurces to NEW R/3.
P-CHains have to manaully COPIED. Here, after Copying, change the InfoPackages to new R/3 system.

CONNECTING TWO SUN SYSTEMS

I am new to sun sytems, I recently purchase two systems ultra 60 and sparc 20 I installed both solaris 7, I also have 8port hub, what I would like to know is how do connect these two systems, I don't want go to the outside world yet just home network.
I connect the two systems trough the hub i am getting a link I can ping the machine I am in it but Ican't see the other machine.
this is what I did configuring the network.
# If config hme0 plumb
#if config hme0 plumb 192.6.6.1 netmask+ broadcast+ up
then I went to
# vi /etc/hosts and added that IP address
# 192.6.6.1 micheal
unfortunately I can't see the other system

Make sure both machines are on the same subnet and of course, that they do not have the same IP address.
Unit 1: 192.6.6.1 / 255.255.255.0
Unit 2: 192.6.6.2 / 255.255.255.0

Connecting two BI systems to one R/3 system

Hi Experts,
We are upgrading our BW 3.x to 7. This activity we are doing on a sandbox server. Now for integration testing we want to connect this BI sandbox to R3 QA system. RFC destination parameters are maintained in both the systems.
Now when we go for source system Restore option from DW workbench, it pops up with message -
"Connection AA is used in the ARQ100 (R/3 QA) source system as a connection ABQ100 (BI QA).
Do you want to delete this connection in the source system? Connection is restored after it has been deleted successfully."
I checked in RSBASIDOC table in R3 QA system, there exists this entry to ABQ100.
My question is - without touching the R/3 QA -> BI QA connection, can I create a connection between R/3 QA & BI sandbox? & How?
or Can we create new connection similar to AA for this new BI sandbox system?
I have already gone thru SAP Note - 775568, but it does not mention anything related to my scenario.
So appreciate help from experts.
Regards,
Vikram.

Hi WernerS,
Thanks for the reply.
Both the BI systems have diff Logical Sys names. And at this time I am not concerned about delta.
But as I mentioned earlier, while trying to restore source system from new BI sandbox server, it is asking to delete the connection from R/3 QA to BI QA which I dont want.
My question is How to establish this new connection without disturbing the existing R3 QA to BI QA connection.
Regards,
Vikram.

One R/3 system connecting to TWO BW systems

Hi ,
When we connect two bw systems to one R/3 system,
could you please exlain what is the imact to SAP and BW in terms of query performance, batch performance,Develoment ,Quality system,security,BW Support.
Thanks in advance.
Regards,
kranthi

Hi,
Well at first thought, i wouldnt go for the Landscape that you are suggesting. Because of obvious reasons:
1. Performance issues while loading, on reporting.
2. Data sources might work fine for one system and not for the other, then the whole setup is hit badly.
3. Security and management of the 2 systems, will be a big task.
4. Jobs would take a longer time if the Batch processes are not sufficient.

Two SCM Systems connected to one ERP System

Hello Experts,
Here again I got a doubt.
Is it technically possible to connect two SCM Systems via CIF to one ERP System?
Because I heard that we could connect more than one ERP System to one SCM System, but not vice versa.
If you have seen a system in production like this, what are the pros and cons of having such a scenario?
Expecting your valuable replies!
Thanks and Best Regards,
Suresh

Hi,
technically it's no problem to connect two or more SCM systems to the same ERP system. We have one for DP/ PP/DS, one for EWM and one for SNC connected to the same R/3 systems. You however might get problems with the bom explosion for planned orders being sent from SCM to R/3.
The bom explosion uses field MARC-APOKZ which is maintained automatically by CIF. If there are multiple SCM system using CIF for product master data the field might not be set up correctly and the bom explosion could be wrong.
As a solution SAP provided OSS note 1576703.

Two BW systems to one R/3 system

Hi,
We have connected two BW systems to R/3. The physical connection is working as it should, but we have problems loading data. The message we got is to do with basic idoc type "BW unknown in source system".
Can anybody tell me what to do?
Regards,
Harald

Hi
Is the 2 BW systems identical?
if they are check your midlewear (usually a Basis task).
If the 2 BW sys are not the same then u need to check the compatibility between R3 and the failing BW (could be Plug in's or SP's).
