hi friends
i m facing problems when i
creating a new source system on BW in AIX pointing to an Oracle database, our bw oracle use 10idatabase ,and we want to connet to 9idatabase(Windows) to get data for BW
(1.)     in /oracle/P01/102_64/network/admin tnsnames.ora I hava add
SJPT =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 68.16.211.177)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = SJPT)
(2) and in etc/hosts I hava add
68.16.211.177 SJPT
(3) in p01adm> tnsping SJPT it is OK
(4)but when i

Creating New Source System

Hi All,
I am trying to create a new source system in BW for the new R/3 client which is a copy of PRD.
So now new R/3 client is 200 and also PRD is 200. I did all necessary steps and i found difficulty when i am assigning logical system based on client. I found key is only client, so as PRD system is already mentioned with client 200 i am not able to create new entries and i hope this causing me error.
So by creating RFC destination directly in SM59 and when i tried to create it says PRD Client already available. Though i have specified new client server name.
Kindly advise.
This is quite urgent.
Thank You.
Best regards,
Bhuvana.

hi,
it seems rfc connection between bw and r/3 not established properly, check with transaction sm59 (ask basis help if no authorization), choose r/3 source system rfc and menu test->authorization. check if user name and password, hostname/ip address are correct.
this doc 'bw r/3 connectivity' may useful http://help.sap.com/bp_biv235/BI_EN/BBLibrary/documentation/B84_BB_ConfigGuide_EN_DE.doc
hope this helps.

Change Default Background User In BW When Creating New Source System

Hi all,
I would like to create a new Source System in RSA1.
In Source Systems > SAP > Create > Connection of source system to BW
the Default background user in BW is u201CALEREMOTEu201D.
How do I change this to another user?

Just want to say thank you. I could fix a problem with your information.
I was searching to change the background user from ALEREMOTE to BWREMOTE as all our process chains were running on ALEREMOTE.

New Source System Client for BW

Hi All,
Currently we have R/3 QAS Clint 102 connected to BW QAS. We want to get rid of this Client 102 and connect a new QAS Client 100 (same server but different Client) to BW QAS. I created a new Source System (QAS100) in BW QAS and did a restore.
My question: How do I get all the Source system dependent Objects like InfoSurces, InfoPackages etc for the new Client 100 in BW QAS? Please help me and I promse to generously reward points.
Thanks, very much in advance.

Hi A.H.P,
I am pretty sure this will resolve the issue. I will come back again and reward 10 points once we apply a working solution.

Steps for creating new source system

Hi guys
We are on BI 7 and ECC 6 now...We are planning to get the data from other source systems (R/3 4.6)which are existed in different place.
Now my question is what are the steps to get the data from this new Source system and whats BI developer role for this...
Example: Inorder to establish the connection between BI and R/3 we need an RFC connection (Is this done by BASIS / BI )? If its BI , then what do I need to ask for ?
afterthat what are all the questions or points that I need to raise to the folks in the meeting...
Please advice
regards

Hi
refer to this link below
http://help.sap.com/saphelp_nw04s/helpdata/en/ac/4a4e38493e4774e10000009b38f889/frameset.htm
Exactly this will be taken up by BASIS team so that at any time if we have any issues with RFCs like RFC connection failure we will not get any data to our targets.
Then we have to raise ticket to basis stating this failure

New source system - same BI system - time estimate

Hello,
The project management of my current project has decided to create a new ECC QA system as copy from existing ECC QA with no data. The BI QA system will remain as it is.
How much work will this create for us in order to re-map the transfer structures in BI to the new system. Will I be able to use the same info sources (off course with new source system)? Any more work needs to be done?
We have about 8 info cubes including stock, sales, purchasing, PCA, loading data via 15 info sources + all masterdata..
Is this a quick and easy fix or a time consuming task?
Regards,
F C

Hello,
Yes, I agree. Just needed a second opinion! Thanks! This is a fresh installation so the amounts of data are quite small..
It should be possible to use the same info sources with some modification on source system and that's it.
Agree?

How to create a DB Source system in BW

Hi Guys,
Can anybody explain me how to create DB Connect source system in BW.
Points will be awarded.
Thanks,
Chinna

Hi Chinna,
Below are the steps to be followed for the SS creation in BW :
Prerequisites :
1.System Number
2.System IP address
3.ALEOLTP like userid and password this is the RFC user ID in the R/3 system. Usually set to communication - must be set to dialog in the R/3 Source System for the duration of the create/restore connection process. Note: the password must be in capital letters.(If all instances are in unicode system)
1.At the time of making the connection, the R/3 source system will need to be opened for client independent configuration.
2.If it is a connection create or restore, the personal userid of the person doing the work must have SM59 access.
Follow the naming convention which is being used in your system.
1.     Logon to r/3 source system using the r/3 RFC userid to check that the userid has been set to dialog user. It is mandatory that the r/3 source system userid be setup temporarily as dialog to create the connection. If not contact the requester to have this done before continuing with the next step.
Note: When re-checking to ensure that the r/3 userid is a dialog user, you may get prompted for new password. Change password, and make a note of the new password. Use this new password in the steps that follow for the r/3 RFC userid.
2.     Logon to BW system using your own userid.
3.     Enter transaction RSA1, In Source Systems, right-click on Source Systems as shown below to create new connection.
4.     In the screen select the appropriate Source System connection type. Suppose your are creating connection for r/3 instance, so in this case we pick the very first option.
5.     A popup window will get displayed asking for the necessary information. To fill in the appropriate information in the that screen you need the following information concerning the r/3 source system.
     IP address (Application Server) &
     System Number
Get this information for the r/3 source system from the SAP Logon Pad.
6.     If Parameters have been incorrectly entered then the following error message will appear : Check connection parameters for the source system.
7.     Re-check and re-enter correctly. If all is good then You will see the following prompt : Please log on as an administrator in the following screen.Click green check to continue.
8.     This will bring you to the r/3 logon screen. Logon using the r/3 RFC id. Once logged on click Check in Check RFC destination dialog box.
9. Consider the r/3 RFC destination screen.
10. Check to make sure that BW system information (Userid, IP address, System Number etc) is correctly showing in the Technical Settings and Logon/Security tabs. Next do the following,
     Step 1: Enter password for the BW RFC userid id.
     Step 2: Save Settings
     Step 3: From Test Menu , click on authorization. Ensure there are no errors
     Step 4: Back out of screen.
11.     System may ask you to logon as administrator again. Logon as in Step 10. This time click on Use in Check RFC destination dialog box.
Connection related processing will start up at this time, and continue for a little while (can be a couple minutes or more).
12.     Subsequently, a dialog box will show up on the screen.
13. Pick option, Replicate As Well.
Replication and activation of data sources & transfer structures will begin.
With the completion of this step you will have successfully established this source system connection. To confirm, right-click on the new source system entry and click on check
14. If the connection is good, the following message with the source system ID will display at bottom left corner of screen : Source system connection is Ok.
Hope this will be helpful to you.

Transport InfoSources to New Source System

Hi.
When implementing BW in our QA environment, all InfoSources, and their related InfoPackages, Transfer Rules, Update Rules, etc.) were created using a temporary R3 QAS source system mapping (ex.TMP). We are now removing this temporary client and I now need to change my InfoSources (along with customized Start Routines, InfoPackages, etc.) to point to a new QAS source system (ex. PRM).
Note that this new source system is already identified as a source system for BW and all DataSources created on TMP have been transported to PRM. Subsequently, all DataSources have been replicated from PRM to BW.
However, I'm having trouble on the BW end. I can't easily
transfer the InfoSources, etc. to the new source system. I've asked some BW / Basis folks and they suggest transporting the InfoPackages out-of and then back-into the BW QA client. Is this possible? Is there a better way to push my InfoSources, InfoPackages, etc. from the old source client (TMP) to the new one (PRM)? Thanks!

Dear Dave
Please do not attempt to change the logical system name your self, as I feel that you have not tried it before.
This is some thing that your basis people have to do. Depending on the size of database this change can take from 2-24 hours (not exact times, but just some thing to show the magnitude of the task).
Good luck

BW: Connect to new source system via special transport

Hello everyone!
I have a BW system connected to an R/3 source system. I have made a copy of the source system. Now I want all my models to be connected to both source systems. I heard that this can be achieved via special transport (i.e. place all source system dependant objects into a special transport request to be imported back into my BW system, but with the new source system assignment). Does anyone have any documentation on how to do this?
Best Regards and Merry Xmas!
Luís Andrade.

Hi Luis,
There are two parts,
1) If you want to transport all your objects from current R/3 system to newly created r/3 system then you can create a TR and use it in SCC4 transaction during client copy. In the same fashion you can use RSA1---> transport connection and use the TR for system copy. After that once you release this TR all the objects will move from one system to another.
2) But if you have already moved all the objects in source system but now you want them to replicate in BI then go to SAP BI system select your source system and then from the context menu choose replicate datsources option, it will fetch everything from respective source system in BI.

Add new source system to BI

Hello,
Our requirement is to load data from a different R3 client to which we dont have a connection yet.
The idea is to create a new connection but keep the existing one.
Is there any automated tool to do this? We would like to avoid the manual creation of all infosources and transformations from the new source system, but to copy them from the existing one.
We found that there is a tool for replacing the current source system with another one (BDLS), but we just want to create this new one in paralel with the current source.
Thanks!!
Pablo

Hi,
what you can do is, create a transport request containing all source system related things like the infosource/datasource assignment, transfer rules... and import that transport back into your dev system. Before the import you should maintain the settings for source system after transport accordingly.

New Source System Issue

Hi
We are trying to connect new Source System to BW. It is ECC 5.0.
When I try to activate the Source System, it generates the following error:
<b>EDI: Partner profile not available
Entry in inbound table not found
Entry in outbound table not found
Entry in outbound table not found</b>
I checked WE20, it looks good. This is very similar to the current R/3 System (4.6). I was able to REPLICATE the DATASOURCE with no issues.
Can you please let me know, how this could be resolved.
Regards,
GPK.

Hi Guru's
The OSS note mentioned was a good one. I did check that OSS to ensure we were on track. There was no loop hole i got in regards to this issue.
I cannot say why it worked for me but I could tell what I did.
1. Deleted the source system, I creted.
2. Created the Source System back again.
3. It worked, but the only difference I noted was that, the icon of the source system is like the BW and not like the r/3 icon. I don't know WHY??
Thank you all for your support and advices.

GPK.

Activating transfer rules for new source system

Hi
we are having 2 R/3 source system in BI. I had activated all the transfer rules with the first source system and now i have created a new source sytem connecting to a different R/3 client. I tried to change the transfer rules point to the new source system using the program RS_TRANSTRU_ACTIVATE_ALL giving the new source system and the infosource name. But i get the error "No Transfer Structure Selected" when i execute the prg.
how can i change the source system without creating the transfer rules for the new source but use the existing transfer rules and just change the source system assigned to it????
Regards
Sujai

Hi Sujai,
There are many cases when this program is used.
When the Trans rules get de-activated due to impact,we need to first replicate the data source and activate the TR using this program.This generally occurs during the data loads in prd.
It does not makes sense to transport it when there r no changes done to the TR.So simply,u can use this program to activate.
If the program does not work,then you are left with the transport option.

Connecting MSSQL as new source system

Dear all,
We want to connect a MSSQL server as a new source system in SAP BW 7.0.
Does anybody has a good "How to..." Paper which helps to connect MSSQL step by step to SAP BW?
Thanks a lot.
Regards
Daniel

Follow the below mentioned steps to create a dbconnect source system.
1. Goto RSA1 -> Source systems. Right click and Create
2. Give some name and description and hit enter
3. a. Con Name : Any name (SQLSRV, etc)
b. DBMS : MSS
c. UserName : Any username which is present in the SQL Server. Eg: SA.
If you have to use Windows Authentication, there is a seperate method :
For windows authentication, you will have to add your Admin login of BI Server to the SQL Server Security logins group (For Eg: If BI Server name is BID and the admin login for this server is BIDADM, you need to add BIDADM to Logins/Users group of SQL Server and also for the specific database).
d. Password : Anything.
e. Con Env : MSSQL_SERVER=<sql server name> MSSQL_DBNAME=<database name> OBJECT_SOURCE= DBO.
For Example:
MSSQL_SERVER=ps14apollo MSSQL_DBNAME=PROJECTSERVER_REPORTING OBJECT_SOURCE=DBO
Here ps14apollo is my SQL Server name. Similarly ProjectServer_Reporting is my database name. DBO should be the Object_Source for most of the SQL Server dbs. I think it should work in your case as well.
f. DB RECO = select or let it remain unselected.
g & h Max Connections & OPT Connections = 0, for unlimited connections.

RFC destination BW could not be created in the source system R3073

I'm creating a source system for our BW (version 7.0) dev client.I'm linking it to our R/3 4.7 QA client. From RSA1 I select create source system, I enter the system information and in the next screen I'm prompted to log on as system administrator. I'm in QA now and the system automatically crated the RFC connection. I test the connection and it runs ok. I log on to the BW client from QA and it logs on just fine. When I exit the screen I get the following message:
RFC destination BW could not be created in the source system message number R3073
Why is this happening? The connection tests just fine.
I'm using RFCREMOTE user in BW and ALEREMOTE in QA with the same password
Any ideas?
thanks

Hi,
I cannot tell you surely the settings for SCC4 now (I can't connect to my sys).
Nevertheless, create your R3QA RFCDEST manually in your BWDEV with SM59.
Create your BWDEV RFCDEST manually in your BWQA .
Perform test and authorization test within SM59 from both sys.
When creating the source system in BW the system will detect the RFC and ask you if you want to use it; accept an proceed the the rest of the procedure.
hope this helps...
Olivier.
