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,

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.
Regards,
kranthi

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

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,

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

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 multiple CRM systems to one backend R/3 and vice versa

Hello experts
Can you tell me whether it is advisable to connect 2 CRM systems to a single backend R/3 and vice versa? Is it recommended by SAP? I require some notes or docs on this. I got some notes on this forum but they are all Internal ones which I am unable to see.
Please help!
Warm Regards
Debolina

Hi,
Though SAP does not recommend connecting multiple systems to one ECC backend. But still it has designed a procedure to achieve this.
Here is the excerpts of the steps required.
1. Execute report MCRM_SETTINGS for each CRM system connected to the ERP
system.
2. Check the entries of the table CRMRFCPAR of the connected ERP system:
The field REM_LOGSYS should be filled for every entry marked with
u2018Created by the MCRM reportu2019.
3. Activate the corresponding consumers in the table CRMCONSUM
(transaction SM30).
4. Internal and external number ranges for Business Partners have to be aligned
manually.
Hope it helps you!!!!
Good Luck.

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 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.

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...

Two NWDI systemes in one landscape

Hi all,
I was wondering if it is possible to have two NWDI systems in one landscape (sharing same SLD) and do track forwarding between these two NWDI systems?
The reason I want to do this is that I want to move the NWDI system to another platform. To avoid a big bang situation I would like for the developers to be able to "forward" the code from one server to the other as they like (over time).
Do any of you have eny experience in this area?
Thanks.
Regards
Paw Iversen

Hi,
First of all thanks for your quick reply.
Our situation is that we have a existing NWDI system connected to one SLD. We would like to install a second NWDI system connected to the same SLD. We would then like to close down the "old" NWDI system. But in order to save the development components from old SLD we need some form of transport to the "new" NWDI system. A possible solution I thought of could be to create new tracks in the "new" NWDI and forward the existing SCs from the "old" NWDI system to the "new" NWDI system.
The reason we want to do this is because we would like to move the old NWDI system to a new platform without doing a system copy.
My question is then if its possible to make this kind of forwarding between two NWDI systems (connected to the same SLD to share component information).
Best regards
Paw Iversen

Two BW Systems to One OLTP Systems.

Hello experts:
We are in the process of connecting two BW systems one OLTP system. Currently the BW system is connected to one OLTP system.
I have many blogs here about this issue. But I am unable to see any answers on how to set this up. Table RSBASIDOC table(in the OLTP system) has only one entry. How can add another entry in this table to point to two BW Systems.
As alwasy points will be rewarded.

Why it is better to filter in the BW system rather than in R/3 ?
I would like to avoid any changes in BW, because of:
- reducing data traffic
- in the source system we have more data(fields), that can be used as filter in EXIT_SAPLRSAP_001
The data sources are unfortunately the same for the both BW systems, so I cannot differ between them.
What do you think about these solutions:
1. Modification in the source system - to pass logical system of BW into EXIT_SAPLRSAP_001 (the logical system is available just before EXIT_SAPLRSAP_001 is called, but unfortunately is not passed as parameter)
2. Pass some dummy selection parameter from BW just to identify BW system ...
May be any other solutions ?

Two Mobile Server for one Backend ?

Hi,
we need two Mobile Server. One for internal access and one for external access.
Is it possible to have two Mobil Servers for one backend system and can I sync all the config between this two servers ?
Regards,
Gerald

Hi
Yes, you can mirror on the hardware,DB and OS level.
This is not possible with your mobile server.
<i><b>One for internal access and one for external access</b></i>
For external access you can expose one of the IP's as a static IP and for internal Access you dont need to expose it.
If you are planning to have two Servers then you will have to get as many licenses from SAP.
PS: reward points for helpful answers

Possible to connect multiple R3/Systems to one XI?

Hi,
is it possible to connect mutiple R3-Systems to one XI?
How does it work?
Regards
Stefan

Stefan,
You can certainly connect multiple R/3 systems to one XI.
1. If your R/3 system release is 4.7 then use point 8 from the configuration guide. (RZ70 transaction collects the system data and creates a technical system in the SLD)
2. If your R/3 system release is < 4.7 (means 46c or 46B, 40B) then you should create a technical system in the SLD.
3. For any other SAP product with ABAP stack (including R/3 47 system), you should check the SAP_BASIS release if it is 6.20 you should apply XI Add-on to use XI Proxy adapter. For SAP_BASIS < 620 you cannot have XI Proxy adapter. For SAP_BASIS > 6.20 you do not need any add-ons (from this point onwards it is NetWeaver)
To find SAP_BASIS release -> SPAM Transaction -> Click on Package Level.
Then create a business systems for each one of them and import them into the Int. Directory when needed.

PO No range when we ink two SRM system with One ECC system

Hello Experts,
We have a client requirement to link Two SRM Systems with One ECC system.
In this case what number range we need to maintain in both SRM systems for PO.
-The number range of ECC PO should get update whenver the PO is transferred from any of the two SRM system.
-We have Extended classic scenario.
-Also PO Doc type is going to be same.
Can we handle this by increasing the buffer of the number range in one of the SRM system?
Any idea...pls help urgently.
Best Regards,
Anil
Edited by: anil.s.verma on Oct 1, 2010 4:33 PM

Hello Anil,
Being in Extended Classic Scenario (leading PO being in SRM, R/3 PO number range is concidered as external because PO number is given by SRM), the only solution for you is to:
1- give same number range interval for PO (internal in SRM system 1 and SRM system 2, external number range in R/3), e.g. 3100000000 - 3199999999
2- in SRM system 2, fill in current number with (for example) 3159999999 and let empty (or current value) in SRM system 1
3- assign, in each system for your concerned transaction type, number range as internal in SRM and external in R/3.
In this way, you will avoid overlaping in R/3 between PO numbers coming from SRM system 1 and SRM system 2
Regards.
Laurent.

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).
