BI System copy: 2 SAP BW system should be connect to same R/3 system

Hi!
We have copy one SAP BW system SR1 to another SAP BW system SR2.
SR1 was connected to SAP R/3 system R31.
As consequence the new SAP BW system SR2 has also in RSA1 --> source system the entry of SAP R/3 system R31.
We would like to restore the source connection in new SAP BW system SR2.
By doing so a pop up comes up with decision to delete an existing connection R31<CLNT>XXX or not to delete this connection to the first BW System SR1.
Question:
Can 2 BW systems (SR1, SR2) be connected to the same SAP R/3 system (R31) and what should we do in this casee with pop up (delete or not delete the existing connection to the source BW System SR1)?
Any helpful information will be very appreciated!

HI
> Can 2 BW systems (SR1, SR2) be connected to the same SAP R/3 system (R31)
Why not? One R/3 system can be connected to many BI/BW system.
> what should we do in this casee with pop up (delete or not delete the existing connection to the source BW System SR1)?
This pop up is coming because you created your SR2 system as a copy of SR1 system. If you have access to your R/3 system, you can check in table RSBASIDOC there will be only one entry R31CLNTXXX --- SR1CLNTXXX which is creating problem
What you can do is to run one FM RSAP_BIW_DOSCONNECT ( in the new system) and delete the entry for R31CLNTXXX and SR1CLNTXXX. Then also delete some correspondign entries from EDP13, EDPP1 and EDP21. Then in the new system , from RSA1 create new connection. I Before creating the new source system connection, in your new BI system you can delete the RFC connection for the R/3 system from SM59. During creation of new connection this RFC will be generated once again automatically. should work fine.
Remember, DO NOT delete connection from RSA1 which in turn will delete all the dataSources.
Please also follow SAP Note 886102 - System Landscape Copy for SAP BW and NW BI carefully before doing ANYTHING with RSBASIDOC.

System copy : how to backup your rfc connections, partner profiles ...

system copy : how to backup your rfc connections, partner profiles (we20) amd ports in IDOC processing (we21) ???
Hi forum,
if you want to copy your production system to your quality assurance system you can export users and later on reimport
it to save work. That's good.
But how about RFC connections, partner profiles and ports in IDOC processing ? Anyway to export and reimport it later on ?
Thank you for your help.
Kind regards
O.Eggert

Hi forum,
in the meantime I found out how to handle this matter. May be this solution is not very elegant, but it works.
As for RFC-Connections there are several tables beginning with rfc. e.g., rfccheck. But 4 of it only differ from one system
to the next. These are rfcdes, rfcdoc, rfcattrib and rfccheck. What I did is the following : I used
brspace -u sapsr3/<password> -f tbexport -t "RFC3"
and quite simply exported these tables. Then I deleted some of the RFC-Connections, both ABAP and TCP/IP. After reimporting
what I exported before all these destinations were availlable again. As for ABAP the password had to be reentered but this
can be avoided, too. Have a look at transaction /nsecstore. The tables behind it are RSECTAB and RSECACTB, rspectively.
Export it after having exported the rfc* tables and reimport it after having reimported the rfc* tables. Very important : enable
the option "consistent export" !!!
It worked this way although there might be better and more elegant solutions.
As for transaction we20 check sap not 182172.
Hope that I could be of profit to this forum.
Kind regards
Olaf Eggert
p.s.
import command : brspace -u sapsr3/<password> -f tbimport.
Them select what you exported before.

Activities post System copy - SAP CRM 5.0

Dear All,
We were having a 3 system (SAP CRM 5.0 SP8) landscape. CRM Dev(CRD), CRM Q (CRQ) & CRM P (CRP) on Oracle 10 and HP UX 11. We have the JDI 7 SP8 instance connected to the CRM dev systemand all the 3 systems were configured as the run time systems in the JDI.
Now we have added a new tier for the Intergation testing called CRM
IST viz CRI there by coming into 4 system landscape (CRD, CRQ, CRI,
CRP). The CRI server is a copy of the CRP box and has been just installed and given to us. We need to do all the post installation activities.
Can you please provide us the proper documentation/ccokbook/check points so as to what all steps to be carried out after this system copy. It would be highly appreciated if you can give us a proper documents & links. We need to give the system to the consultants and before that we need to carry out all the post refresh activities, please help us in this urgently.
Thanks in advance.
Awaiting response.
Thanks & Warm Regards,

System Copy SAP NetWeaver Process Integration 7.1 documentation incorrect

I don't want to move my system to another system. I just want to do a Database refresh. That option is not available when I run SAPINST.
I see the option for database refresh in the manual, but it's not a sapinst selection

With this procedure you can refresh the content of an existing database without having to copy the primary application server instance and to reinstall additional applications servers.
I'm using the latest SAPINST and I have the correct DVD from Service Marketplace.
This database refresh option appears in both the "distributed system" selection under system copy --> target --> distribute system.

Is that the correct choice? Why is the documentation wrong?

System copy - CUA how to keep (merge) some of the old target system users ?

Hi,
can anyone suggest if the following is possible and if so, the best way to enable the following within a CUA landscape :-
Standard SAP System Copy of Production to QA.
Cleanup of "Production" user master records in the QA system to remove users not required in QA.
Resend a set of test user id's which existed in the pre-system copy QA system (and still in the QA CUA master system) to the newly copied QA system to merge with the cleaned up QA user master.
Re-link the new QA system with the QA CUA master system to transfer the "merged" list of QA users into the QA CUA.
I've simulated the above on a test server but the process of sending down the sub-set of old QA test id's from the CUA master (using report RSCCUSND) does not create the users in the QA client even though the report itself appears to have transferred the users. Checking SU01 on the target CUA client shows no user has been created and there are no idocs passed from Master --> Client.
Other than either exporting the QA users to a transport before the system copy (for re-import after the system copy to replace the copy of the production user masters with the old QA list), or using the "production" users in QA following the system copy I can't seem to find a way of merging some of the old QA users with a cleaned up list of production users in the QA system post system copy.
If anyone knows of a way to do what I'm suggesting then please let me know.
Brian.

Hi Brian,
I don't think there is an option, directly.
However what I would do is.
Before System Copy
On the QA Side:
1) Create a new client in the QA and only copy user masters in the empty client.
2) In this new client, keep only those users I need after client copy.
3) Take help from ABAP guys to include all usr* table entries (with MANDT field selected only for the new client) into a transport request and save it for later use.
On the Production Side:
1) Export user masters of the production client
2) Create a new client in Production and re-import the user masters
3) Work on the new client to cleanse the unwanted users.
4) Re-export the new user master of the new client and save it for later use.
After System Copy
1) Import the exported user masters from the production server , thus overwriting the client with the users selectively chosen from the production user master.
2) Import the transport request to merge the older users from the QA.
I know this is a crude way.. anyways..
Hope that helps,
Siddhesh

BDLS Conversion after System Copy fails

Hi All,
We are doing a Homogeneous System Copy on a AIX 5.3/Oracle 10.2.0.4/ SAP ERP 6.0 environment.
After the system copy we had to run BDLS to convert logical system names in tables. Except for 3 tables namely EDPP1, TBD05 and TBD06 the BDLS run was successful.
We tried to convert the logical system names in these tables by running BDLS for these tables individually however they failed again.
The error was - "Error in field of table. Manual correction required"
I checked SAP Note 121163 and it is mentioned in this note -
"If the new logical system name already exists in the system, it can cause errors for tables in which the logical system is key field or
unique index (for example, COFIO1). In this case the number of converted entries is smaller than the number of selected entries."
And in this case a manual post-processing is required. How do I go about doing this manual post-processing?
1. Should I maintain these directly at the table level - which is cumbersome as there are a lot of entries?
2. Or using a small ABAP program?
Please let me know if any other information is required frommy side.
Thanks, Dibya

Hi,
Yes ofcourse, you need to check all settinfs, once you copy teh system you are going loose all RFC's and Source and Destinations ectc, so adject all that settings.

BI System Copy of disconnected systems

I am SAP BI person and need some suggestion regarding the BASIS expertise.
If I have two BI systems (Say BI-1 & BI-2). I do not have any transport path maintained nor any connection between these two servers.
If I develop some objects in BI-1 system, can I copy to BI-2 system using some mechanism or custom software. I can also go with the system copy.
Here I have two questions:
1. If both the systems are running on different OS platform
2. If both the systems are running on same OS Platform
What would be the possibility in above mentioned cases? Can I copy the system or objects?

Hi,
Here I have two questions:
1. If both the systems are running on different OS platform
Transport it, else copy the CoFiles and DataFiles from B1 to B2 and try
2. If both the systems are running on same OS Platform
What would be the possibility in above mentioned cases? Can I copy the system or objects?

After system copy

Hello
I have connected my Productive BW 7 system with a 3rd party DB.
After the basis perform a system copy from Productive BW to Quality BW are there
any after copy activities to refresh also the connections and the datasources for this connection to point to the
3rd party quality DB?
I mean for ABAP system we can perform through transaction bdls etc. some after copy activities.
Are there similar activities between BW and DB connect systems.

How to perform system copy using standard sap method (sapinst)

Hi guys
pls tel how to perform system copy using standard sap method (sapinst) and to perform enterprise portal RESTORSTION.
thanks
kamal

Hi Kamal,
I have done a system copy of the production portal to a sandpit system before. The system copy export import method works very well, and is easy. For my portal, the whole procedure took me less than 6 hours.
1. Go to this page: System Copy and Migration
2. See the videos "Demo: How to Perform a System Copy Export" and "Demo: How to Perform a System Copy Import".
This should give you the basic idea.
I did a systemcopy using sapinst. If I remember right, this is the steps I performed:
1. On target host, Installed a new Central services.
2. On source host: Ran sapinst system copy export for Central Instance and Database instance. This created two export files (depending on your database size).
3. Used the export files created in previous step to run the import step in target host.
4. Some post processing steps, like configuring sso, creating systems in system landscapes, configuring WD JCos etc.
Let me know if you need more help.
Cheers

SAP ECC 6.0 EHP5 with Opentext VIM 7.0 - Question on System Copy / Refresh

Hi
We are planning to perform a system refresh of our QA systems (platform: Windows / SQL 2005). The ECC system has Opentext Vendor Invoice Management 7.0 on it.
I was looking for some documentation explaining the Pre and / or Post system copy (refresh) activities specific to Opentext VIM, but could find none so far.
I have tried on Opentext website, SAP SMP and Google.
Are there any VIM specific tasks for system copy ?
Is there any documentation that you can lead me to ?
Any help / lead is appreciated.
thanks
Sree

There shouldn't be any specific procedures for the system copy as there is OpenText VIM add-on installed on the system. As the add-on's are stored in the database you just need to restore the database and do the post refresh activities.

Odd System Copy

Hello Experts,
I am performing a homogeneous system copy on linux w/ MaxDB. The source system is really more like source systems. Using one database instance (XDB), I have an ERP 6.0 EHP4 system (XS1) and an EP instance (JS1). My first step was to export the database using the Database Manager; then I made the export available to the target system. The system copy for the abap application server went without a problem. Now I am having trouble with the J2EE system copy.
My assumption was that the single MaxDB export contained both the ABAP schema (SAPXS1) and the J2EE schema (SAPJS1DB). Also, I assumed since XS1 and JS1 are two separate instances sharing a single database instance, then I would also need to complete two system copies. Were any of those two assumptions false?
My hope was to skip the recovery w/ initialization step during the J2EE system copy since the DB containing the J2EE backup should already be loaded in the target database host. The error I'm encountering on the J2EE system copy is "You can not use existing instance while installing with backup/recovery method." Sadly, that error message is very straight forward and doesn't leave much hope to complete both system copies using this method.
A system copy for both ABAP and J2EE stacks ins't the correct path, is it?
Any help is appreciated.
Kind Regards,
Zach Shay

Markus,
Update #1:
It appears that sapinst will allow me to do a system copy of the J2EE stack via the first method.
Standard System Copy / Migration (load-based)
What is a bit queer on the whole situation is the wording that sapinst is presenting me. sapinst asks me for a "Migration Export." I supply the directory with the label, "JAVA." Then sapinst asks me if I would like to use the existing database or create a new one. It allows me to select use existing database (which is a step past what is allowed via Homogenous System Copy)! However, sapinst then asks me for another Migration Export.... Unfortunately this Migration Export has the label "SAP:MIGJDMP:701:::*", and is a label not present in any of my export directories (or subdirectories).
The labels I have from the ABAP and Java exports are:
SAP:JMIG:701:*:*:*
SAP:MIGSDM:701:MIGRATION:*:*
SAP:MIGAPPS:701:MIGRATION:*:*
SAP:MIG:*:EXPORT(1/:*:*
Is this MIGJDMP Migration Export related to a database export via R3Load or something similar? If so, how do I get this?
\[reading more documentation...\]
Thank you,
Zach

MDM 7.1 installation / system copy

Hi,
New to MDM administration here so please help. I have a MDM 7.1 Production system running on windows and ms sql. Now i need to create a new QA system as a copy of this prod system. I am confused as to whether i should use the archive/unarchive procedure to move the repository content or shall i use the SQL backup/restore to copy the DB. I have about 8-9 small DBs in my MDM system -- around 1 GB each and I have one big DB around 200 GB that I believe has all the master data.
Shall i first copy the DBs and then do MDM installation or shall i only do a fresh install and then archive/unarchive the repositories ?? will archive/unarchive bring over all my data and configuration like connections to PI, ECC system etc ?
Also, i would like to know how to modify the connections etc in MDM to point to the correct QA systems after a system copy ?
Thanks,
