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.

Possibility of connecting multiple BW systems to single ECC system

Hi all,
I have a requirement in my company to connect multiple BW systems to single ECC system. Would like to confirm whether this may not be supported by all BW extractors in particular the delta mechanism?
For logistics extractor in ECC side in RSA7 it stores BW System as target which shows they support multiple BW systems as target, but for FI extractors which keeps delta timestamps in BWOM2_TIMEST table, it doesn't store the target system. I'm afraid if we connect multiple BW systems to single ECC system, some of the delta records might go to one BW system and some others go to the other BW system when we execute delta load in both BW systems.
Thank you very much in advance.
regards,
arie

Hi,
You can very well connect multiple BW systems to single ECC system and you will not miss any delta as well. In the source system for each delta data source a delta queue is maintained for each target system.
for e.g. I have two BW systems ABW and BBW connected to AEC system then for 0FI_AP_4 data source we will have DQ1_ABW and DQ2_BBW as two different delta queues (I am not following any naming conventions, actual names will be as per the target system logical name).
The settings maintained in BWOM2_TIMEST table are across the system and they define some global settings e.g. till what time the FI data should be extracted in BW system, for e.g. the time maintained is 2.00 AM then though you do extraction from multiple systems same data will be extracted till next time interval occurs.
In summery you can very well connect multiple BW systems to a single ECC system.

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.

Error connecting multiple BW systems to one OLTP system

Hi BW Gurus,
As part of a major project we had to create a copy of our production BW system and thus have two BW systems connected to one production R/3 system. Before we proceed with the production systems, we decided to try it out with our staging systems.
1) Created a copy of STG BW (already connected to STG R/3) and renamed it to TST BW.
2) Transaction BDLS, renamed the logical system ID
3) Made sure all partner profiles were available and active
4) Since there was no connection between TST BW and R/3 STG, tried to activate the source system in TST BW. As per OSS note 886102, tried the restore functionality but we are running into a strange error.
Table RSBASIDOC in the source system already has an entry for STG R/3 and STG BW with IDOC TYP ZSSA015 and Prefix "SA" and now it complains that since this prefix alrady exists, it cannot create another entry with the same prefix for TST BW and STG R/3. It gives us the option to delete the existing entry and create a new one for TST BW. This in turn de-activates the delta between STG BW and STG R/3 and we can successfully initialize with the new system.
This process turned the queue entry in RSA7 red for STG BW and created a new one for TST BW (green). Delta stopped working for STG BW.
How can I have both the systems connected and run delta process simulataneously? I have read OSS note 775568 but this is after the fact that the two systems are already connected.
If I have to start from scratch, can someone please outline the steps involved?
Do I have to restore the source system or is there an alternate way? I cannot see how the delta would work if there is no connection betweeen the two systems.
Do I even need to worry about initializing with the TST BW System or can I just run the delta process and it would automatically add another entry in RSA7.
Any help would be truly appreciated and rewarded!!
Thank You.
Sreedhar

Looks like a much bigger issue than that. We did create the partner profile in WE20 but that didn't help either. It still complains about the prefix. This 2 Character prefix value is actually derived as the concatenation of the first letter of the BW system name and starting alphabet in a sequence. In our example STG BW has prefix of SA and the basic idoc type is ZSSA015. Based on this, TST BW system should have prefix of TA and basic idoc type might be ZSTA016. The program initially looks at RSBASIDOC table for source system and finds value SA and complains that this cannot be used again.
I have seen messages in this forum where people have actually done this and hopefully someone would reply back as to how to resolve this issue.
My main question though is, do we have to restore or activate or do not have to do anything to the source system after the copy of BW systems? None of the above three options seem to work for us right now.
Any ideas?
Thank You

Is it possible to connect multiple R/3 systems to one APO system?

Hi,
Is it possible to connect multiple R/3 systems to one APO system?
Kind regards,
Kris De Smedt.

Hi Kris,
Yes, you can connect multiple R/3 systems to one APO system. All you need to do is to maintain connection parameters of all the R/3 systems with APO. (i.e. RFC Destinations, logical systems, partner profiles etc.)

Connecting to Multiple ECC systems via one Gateway system(Dynamic System Selection)

Hi Experts,
We have multiple ECC systems and one Gateway server. We want to connect to these different ECC systems using one GW system.
I have created System Aliases for these ECC system in GW system. For a service, i added 2 system aliases.
Now we are looking for the solution where UI can provide the system alias (it wants to connect) as a parameter while calling oData Service.
Please help.
Regards,
Rohit

Hi Rohit,
we have a similar scenario where we have two system aliases for one service. Both aliases point to the same system, but different clients; it should not make a difference though, having different systems. The feature you are looking for is Multiple Origin Composition (MOC).
There are a couple of things you have to consider:
in the SEGW the entity to be called has to be marked as addressable
the URI of the service needs to include the tag for MOC (;mo) --> http://sapgw.domain.org:8000/sap/opu/odata/sap/ZSOME_SERVICE;mo/entityset
Without the ;mo the call will be routed to your default alias. The ;mo will route the call to both systems. Using MOC will generate an additional key property into your entities --> SAP__ORIGIN. The property is the alias. If you want to route to a specific system you have to provide the SAP__ORIGIN like providing normal key properties in your requests.
This will look like this:
<content type="application/xml">
<m:properties xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices">
    <d:SAP__Origin>SOME_ALIAS</d:SAP__Origin>
    <d:Identifier>SOME_IDENTIFIER</d:Identifier>
    <d:Doublet />
</m:properties>
</content>
The original Entity only consists of the key property "Identifier" and the property "Doublet". "SAP__ORIGN" is added via the ;mo.
Hope it helped...

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

Multiple CRM systems to one R/3 system

Hi all,
Is it possible to connect Two CRM systems to the same R/3 system?
My gut feeling is, it is impossible to do that. Am I correct or is there a way to do it.
Any help will be highly appreciated...
Thanks
Jothi

Hi,
I it is very much possible to do this. SAP provides the functionality in the form of Multiple Backend Exchange feature. Please refer to SAP Note 853430 and also the link http://service.sap.com/crm-mep.
Also you can find a presentation in the link https://websmp107.sap-ag.de/~form/sapnet?_SHORTKEY=01100035870000579336&_SCENARIO=01100035870000000112&_OBJECT=011000358700002029062003E.

Multiple SAP Systems In One MSCS Cluster

We have installed a NW 7.0 EHP abap stack in a MSCS Cluster with 2 nodes.
This was installed as a standard Cluster Install.
We have now higlighted a requirement to install a 2nd (Java ) instance in this Cluster Group.
The NW 7.0 EHP1 documentation and Note 1321854 shows that multiple SAP systems in one MSCS cluster is supported.
The documentation, however, is not clear if the 2nd instance can be installed when the 1st instance was installed without the preperations for Multiple Systems.
There are no further documentation or guidelines to help.
Has anyone come across this situation or managed to install 2 SAP instances in one Cluster Group based on Windows 2003, SQL Server 2005.
Regards

I am not quite sure if I understood your problem completley. But let's see...
Usually you use on on MSCS Cluster Group per SAP instance. So you have your already existing NW 7.0 ABAP stack in a separated Cluster Group, and you create a new Cluster Group for your new Java system.
You can find more information about it in this guide here on SDN:
Link: [High Availability;
More information about High Availability Setups for SAP System can be found here on SDN:
Link: [High Availability]
If you want to use the same database for your clustered ABAP stack and your new Java stack you can do a MCOD installation.
Please see Link: [SAP Note 388866 - Multiple Components on One Database - Installation|https://service.sap.com/sap/support/notes/388866]
Hope this helps.

CS6 - Is it possible to rotate multiple objects independent of one another?

CS6 - Is it possible to rotate multiple objects independent of one another? In other words selecting say 9 object in a grid then rotating the all 30 degrees on their own axis.

I forgot Transform > Again won't rotate each layer about its own centre.
It can be done, though. Record an Action of a layer being rotated and followed by Opt+] or Alt+] to target next layer. It should look like the screenshot below. Use it by first running it on the lowest target layer in the stack then running however many more times is required.

Is it possible to connect a DEV System to more than one SAP Solution Manage

Hello,
My system DEV is already connected to a first SAP Solution Manager, I would also like to reconnect the same system so that it communicates and will be monitored by a second SolMan.
Is it possible to do so and the do the operation involve any risks ?
Thanks for your help
Regards
Ben

Hello,
This is possible in many scenarios. Often this is done to distribute load, for example on Solution Manager will do the Service Desk Function, one may do ChaRM, one may be doing Monitoring & Reporting, one may be doing Diagnostics.
In these cases a managed ssytem can be connected to many Solution Manager systems.
However as Mateus has pointed out, you cannot connect one managed to two Solution Managers and do SMD on both Solution
Manager systems, but you can have more than one Solution Manager doing Diagnostics.
Even in the case of EWA, while you can connect a Managed system to multiple Solution Manager systems and have then generate a report, one of the Solution Manager systems must be defined as the Master.
So the specific scenario may place some restrictions on connecting a managed system to more than one Solution Manager,
but for most instances it can be done.

Paul

Multiple CRM system with one R/3 system, possible?

Dear all,
I wanna see if multiple CRM systems can hook up to one R/3 system. My hunch is that this is not possible, because information exists in table such as R/3 CRMKUNNR for BP data would not be able to distinguish which system an entry would need to send to for syncing.
Am I right?
Thanks,
Kirby

Hi,
Well there is also the MDM (Master Data Management) application with SAP Netweaver. Which actually makes things a lot easier with a number of CRM installations with multiple R/3 instances.
Maybe you would also like to do some read up on MDM.
Thanks, Debasish

Multiple TREX systems with one portal

Hi all,
is there any possibility to connect more than one TREX system to a SAP Netweaver portal. Help and all other documents I found always talk about entering the name server into nameserver.address and it seems to me, that this is no multi value field.
We have a TREX system in place that does all the indexing regarding conten of the portal and connected third party systems. In addition there will be a second TREX system to index our content management system. Of course I know that it is possible to set up multiple hosts within one TREXsystem but the installation guide has several notes that indicate it might not work with the scenario and hardware we are having in place.
As far as I understand there is no chance to directly address the TREX web server from a portal I always have to go via name server. Any help or hint would be appreciated.
Thanks in advance
Holger Müller

I have implemented TREX 7.1 64-bit on a cluster (note that SAP doesn't support this). I have installed the first TREX on server1 and the second in server2. I have to do lot of registry tweaking in Windows sever 2003 to point these guys to the shared SAN storage.
I am using one as a master and second as a slave. So, I am getting high-availability for both search and also indexing.
I am using server1 as a primary name server address and server2 as secondary in Visual Administrator. Let me know if you need more info.

Multiple MiniSAP systems on one machine, with remote access

Hi,
I'd like to ask if it is possible to install multiple versions of MiniSAP (6.10, 6.20, 2004, 2004s) on the same machine? An important requirement would be to be able to access all these systems remotely.
Maybe the best option would be to install these onto different virtual machines which can be run at the same time. In this case how should I set up the router for remote access? Also, how can I define the SAPGui entries on my laptop to access these systems?
Many thanks,
Tamá

If you are using DHCP (in most cases yes), after setting up virtual machine you will get another IP adress for that virtual machine, so that you are able to connect to this machine and of course connect to SAP system running there. You don't need to do any settings on router.
In SAPGui you will create as many entries as you have SAP systems.

Multiple SAP systems on One database

Hello,
We are planing to install multiple SAP systems like SM, ERP on one database with multiple DB SIDs, it means each SAP system has its own Oracle instance. We know MCOD has only one DB SID (one oracle instance) for multiple SAP systems.
Is it possible to set up the landscape like this? Is it supported by SAP?
Can any body advice?
Thanks,
Kris

Technically, it is possible.
But SAP Does NOT support it. The only method to install one set of binaries (one ORACLE_HOME) that is supported by SAP is to use MCOD (all components are installed in one Database)
