Change source system from A to B

Hello,
We have a lot of infosources which have a connection to datasources from source system A. Some of that infosources contain formulas. Now we have to change to source system B with the same datasources and even the same content. What´s the best way to change without losing or filling in again the formulas and is there a way to do it not seperately for each infosource but for all infosources together, so simultaneously?
Kind regards,
Jos

Hello Jos!
Have a look at this document:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/0e38e10f-0401-0010-2ea1-f6fad5969c47
It contains recommended scenarios for client copies and such. I think it will be useful to you.
Kind Regards

Change Source system Tech.Name

Production : PRE -
> PRB
PRE-Production : PPE -
> PRE
We make a copy of our production BI to Preproduction BI (PPB) we follow note # 886102. We want to connect this system to our pre production ERP (PPE).We already run BDLS change the logical system name we created new RFC created which is pointed to new R3 system .Problem is when we are going to run Tcode RSA1 in source system it shows old Tech name PRE600. We are unable to activate the source system.
We can create new source system (PPE),but All our BI objects mapped with old source System (PRE600). I am afraid to change thousands of BI objects ( change source system from PRE600 to PPE600).
Is there any work around we can change the Logical Source system Tech.Name? or some batch job which change the source system name for all BI objects.
Appreciate your earliest reply.

Change Source system ID

Hi Experts,
We did a system copy of BW system alone, and when we tried to restore the connection with the source system, i am getting the following message.
Source system cannot use any of the proposed connection names
Message no. RSAR362
Diagnosis
Every connection to a source system is named using a unique two-digit identifier. Source system DEVCLNT030 does not accept any of the proposed values.
The last proposed value was BA.
System Response
Source system has not been connected.
Procedure
If you want to recreate the source system from BI information, then you can only use a single value, namely BA, because the connection already has this name in BI.
Delete the existing connections in the source system or contact a BI consultant.
BDLS was successfull, and returned no errors.
I checked the source ID in the RSA1 and it exists, how do i change this value.
Thanks in advance
Praveen

Hi Praveen,
Login to ur SAP R/3 or ERP Source System and go to table RSBASIDOC.
Put the R/3 logical System Name and BI logical system name as parameters and see the table values, i am sure the 2 digit unique identifier value will be the one giving u the problem.
This error comes after system copy of source system as ur system still behaves as Production System (the one from which it is copied).
Execute function module RSAP_BIW_DISCONECT in SAp R/3 System with parameters as ur R/3 logical System Name and BI logical system name and option forced delete as X. to delete entry from RSBASIDOC table.
now go to BW system RSA1 > Source System> restore ur system.
Hope it helps
Thanks

Does not allow to change source system in Variant

Hi Gurus,
I am creating a variant for the program RSIMPCUST, but it does not allow me to change source system name. It is showing me gray color. Do you how to fix this issue ?.
Thanks
Liza

Hello Liza,
Did you try my solution?
[Re: Change source system name in variant in BWQ]
There are solutions to change variants properties, but that particular program has the logsys parameter not able to change, so you cannot change the value of that variant (only with debug).
It's best to go for that solution I already provided to you...

How to design EDW for source systems from different Time-Zones

How to design EDW for source systems from different Time-Zones?
Suppose IT landscape has a global BW in New York, and source systems in americas, europe and asia, then how the time-zones effect on time related things like delta selections on date or timestamp etc.

As you said BW is global in NY, your source system must be global too. People from various locations can connect to same source system and thus timestamps for delta is always maintained as 1 single time. We have same scenario in our project. Our R/3 system is used by users in US and Europe. So we run deltas twice in day to make sure we got deltas from both locations.
If scenarios was such that all locations connect to separate R/3 system, then obviously you have multiple queues. That is unique delta queue for each source system so deltas will be pulled as per data in respective queues.

How to Delete a Source System from BW System

Dear All,
I have a request to delete a UDC based source system from a BW system. Can you please let me know the steps to be followed to delete a UDC source system.
It would be helpful if you provide steps to delete a SAP Source system also from a BW system.
If there are any such documents for both the cases, please provide me the link.
Thanks to all.

Hi,
      Go to RSA1 T-code
      Click on source System on Left window
      select the Source System
      right click on it and Delete.
      click yes if you want to delete the PSA table as well

Change source system name in variant in BWQ

Hi Gurus,
I created a process chain for global seetings for unit of measurement and fiscal year variants and transported to BWQ.
In BWQ, I found the source system name in variant is showing ERD source system name, but I need to change it to ERQ source system name. Any advice how to change source system name in variant in BWQ I would appreciate it.
Thanks
Liza

Hello Again Liza...
I had the same problem but I didn't need to include in process chain...
So to execute periodically you can change it in debug mode, not the best solution...
But since you need to use it in a process chain, you should copy that program to one of yours Z.
Do this:
Go to transaction se38 and insert the program name "RSIMPCUST".
Click on the button of "Copy" (Ctrl+F5).
Change the source program name to ZRSIMPCUST (or whatever you want)
Click Enter
Click the button to mark everything (F8)
Click Enter
On the next window of the name of the include click enter (leave it blank)
Click on the button Change of your Source Code
In line number 54 you'll find this in Selection Screen part:
PARAMETERS: logsys TYPE rsa_logsys MODIF ID p01.
PARAMETERS: logsysnm LIKE tbdlst-stext MODIF ID p02.
Delete those two lines and insert this ones:
PARAMETERS: logsys TYPE rsa_logsys.
PARAMETERS: logsysnm LIKE tbdlst-stext.
Now click on Activate button (Ctrl+F3)
Now you have a new program just like the old one but you can change the source system to whatever you want!
Please assign points,
Diogo.

Will accepting an update aotumatically change ny system from 7.1.2 to 8? i do not want ios8

Yes. That's what an update does. It changes your old version to the new version.
If you don't want the new version, don't install the update.
Why don't you want iOS 8?

How to change the Source system from ONE DataSource?

Hi,
I'm trying to change a DataSource's source system (active with dtp and transfer rules), but it's not possible to do it in change mode because the field 'Source Sytem' is not enabled. I know I can use the BDLS transaction but I understand that this is for change all Datasources and I only want to change one of all.
Thanks for your help

Hi Marcel,
As I understand apart from file and web services all other data sources are replicated from underlying source system. BDLS transaction is used to change the source system but in case of system copy activity and it is necessary because the data sources points to old source system.
In your case as I understand you will have to replicate the current data source directly from underlying source system and then build the rest of the flow. May I know how you have got this single data source for which the source system is different?

Durgesh.

How to Change Source system type of ECC6.0 in BW system

Hi BW Experter,
   I connected ECC6.0 PRD system with BI7.0 PRD system , the connection is successful,
but the source system type of ECC6.0 PRD is not collect . The ECC6.0 PRD is as a
BW system type in the source system list of bw system .
   I found that Tcode RSA1 has ever been run in PRD ECC6.0 , So I did a connection testing of
ECC6.0 QA with BI7.0 PRD .
     Step 1. Connect ECC6.0 QA with BI7.0 PRD , ECC6.0 QA was as SAP system type in source system list of bw system .
     Step 2. Run tcode RSA1 in QA ECC6.0
     Step 3. Delete connection of ECC6.0 QA with BI7.0 PRD .
     Step 4. Connect ECC6.0 QA with BI7.0 PRD again , ECC6.0 QA was as SAP system type in source system list of bw system .
   I want to know how to change ECC6.0 PRD source system type to SAP .
If it can't been change to SAP ,Is there any impact when ECC6.0 PRD is as bw system type in source system .
Thank you for your help .

I got the soulution from note: 1087980 - ECC Source systems appearing in BI folder
Summary
Symptom
Source system connection for an ECC system appears in the BI folder, rather than in SAP folder, as expected.
Other terms
Wrong folder,RSA1, RSBASIDOC, RSAP_BIW_DISCONNECT
Reason and Prerequisites
Transaction RSA1 was inadvertently used on an ECC system , thereby creating a 'Myself' source system entry in RSBASIDOC table
Solution
This is just a display issue and does not cause any operational issues. Therefore, it need not be corrected, especially if the ECC system in question is used as a BI system as well.
If it is absolutely required that the ECC source system appear in the correct folder, perform the following steps.
1. Check that an entry with SRCTYPE 'M' exists in table RSBASIDOC table of ECC source system.
2. Note the values for SLOGSYS and RLOGSYS. It should be same.
3. Run the function module RSAP_BIW_DISCONNECT in the ECC system.
   NOTE: Never run that function module in a BI system!
4. Enter the following values :
I_BIW_LOGSYS   <RLOGSYS> as noted in step 2
I_OLTP_LOGSYS <SLOGSYS> as noted in step 2
I_FORCE_DELETE <X>
< DO NOT ENTER ANY VALUE IN THE FIELD - RFC target sys !!!!! >
5. Go to RSA1-> Source systems in the BI system connected to the ECC system.
6. Select the ECC source system and select RESTORE in the right click menu.
Now the ECC system should appear in the SAP folder.
If running RSAP_BIW_DISCONNECT results in an error like OTHER_ERROR, please check if a valid RFC connection exists in transaction sm59.
If the myself source system connection cannot be deleted in any case, log a service marketplace message with SAP Support.

Change source system in Infosource

Hi
I am working on BI7. I have one isse. For an infosource source system has been assigned to client 100. I would like to change it to 200. Pl let me know how to make this change.

Hi
I didn't get your question,how a infosource is assigned to source system,your data source will be assigned to source system and your infosource and data sourece will be assigned to each other..
delete the datasource from source system 100 and create a data source in 200 and assign it to your infosource(i am considering both 100 and 200 source systems are assigned linked to your BW system via RFC(SM59))..
Hope it helps
Thanks

Change Source System in Transfer Rules

Dear All,
I need to change the Source System assignment in Transfer Rule from System "A" to System "B", as the System "A" no longer exists.
I came across the T-Codes BDLS/BDLSS but aint sure if this can help me rectify the issue.
Request you to please provide some inputs.
Regards,
Nitin S.

Hi
if you change the source system you may face the problem.
first you can replicate the Dat sources on B, then you can map the info source with your respective data source.
else it will not allow you for thr mapping.

Disconnet a Source system from RSA1

Hi!
I changed all the neccessary BW objects from one SAP ECC system to another one in my SAP BW system via tcode BDLS (e.g. EC1CLNT500 --> EC2CLNT500).
Now I would like to delete the old entry of EC1CLNT500 in RSA1 --> source systems.
When I do so I get the following error:
Source system cannot be deleted in Content system
Message no. RSAR670
Diagnosis
If a source system is deleted in the Content system, the shadow tables
for all source system-dependent objects for this source system release are also deleted. You can configure a user as a non-Content user by using a SET-GET parameter. You can then use this user to delete the system, and then the above-named objects are not changed duringdeletion.
System Response
The function is completed.
Procedure
Logon as user ACTIVATE, and repeat your actions.
Can some one tell me how to proceed here?
regards
Jürgen

Hi!
The table RSBASIDOC does not have the entry for new SAP BW system that I would like to disconnect.
Only the value of the old SAP BW system is there...
How to proceed?
Thank you!

How to change source system in SAP BI

Hi,
In Sap BI we are having a source system ECC1CLIENT100, based on this we developed all the data modelling, now due to some reasons we made a copy of the souce system ECC1CLIENT100 to ECC2CLIENT100 and we removed ECC1CLIENT100 from SAP BI connections, Now what changes we have to do to connect the ECC2CLIENT100 to BI in the place of ECC1CLIENT100, please give me step to step what to do for sucessfull operations, Both the clients are having different IP, SYSTEM ID,
Thanks in advance,

Hi Bazi,
-->you need to maintain RFC to the new source system
-->delete old source system
-->create source system connection from RSA1
--> Run BDLS to point the data sources to new source system. This should be run on both BW and ECC.
You will need to run this BDLS several times
