Logical system name changes

All,
Has anyone faced a scenario where you need to change the logical name for any SAP system?
For instance:
System      Logical Name                                                    System      Logical name B
BW                      A                     system is pointing to            ECC                  B
ECC will be upgraded and system name will changed to C
Is that possible? If so do you forsee any issues? Can we switch ECC B to ECC C with no issues?
I appreciate any help.
Regards

Hello Mike,
please elaborate a little more your inquiry. Are you talking about the ALE logical name changing? For this, please check the following notes:
#544509 ALE: Converting the name of the "logical system"
#121163 UTI: Logical System names
If you're referring to a domain name changing (like a Windows domain name change) or a hostname change, please refer to the following notes:
#96317:   Host names during R/3 upgrade, tips & tricks
#1275273: Hostname change on 7.10/7.11 java stacks
#757692:  Changing the hostname for J2EE Engine 6.40/7.0 installation
#8307:    Changing host name on R/3 host: What do you do?
#1070561: SMD: Best practice for planned domain name changes
and on the following SDN threads:

Re: Domain name change
Re: Change the Domain Controller

Or, lastly, you're talking about a SID change? On this case, you must perform a system copy to change de SID, please refer to the following note:

I hope this information helps.

  • Logical system name change

    Hi all,
    Now my BI development is pointing to R/3 development. R/3 logical sytem name is bbbclnt100. Now all my datasources are pointing to this logical system. Our basis people are going to change the logical system of R/3. Please tell me the repercussions? what will happen to my datasources?
    Thanks in advance

    Anni,
    Change logical system name and run BDLS job to adjust. Do not change souce system. If you change source system all transfer rules will get deactivated.
    Check: [Conversion of Logical Systems|http://help.sap.com/saphelp_nw70/helpdata/en/33/c823dbaea911d6b29500508b6b8a93/frameset.htm]

  • Logical System Name changing

    Dear Team,
    We had upgraded BI system from 3.0B to BI 7.0. At the time of upgrade dev
    copy(shadow system) logical system was not changed because most of the data is coming from ETL. Now we want to test the extraction from R/3 Dev.
    R/3 Dev is already connectwed to BW dev 3.0B, Now we need to test
    extraction from R/3 Dev to BW dev copy server( NW2004SR1 ).
    Here we are facing a problem with Logical system. While upgrading the
    same logical sys was copied to BW dev copy.
    What is the procedure to change the existing logical system name in BW
    dev copy and establish connectivity with R/3 dev?
    what is the impact if we run BDLS transaction.
    Thanks& Regards,
    Satish.K.Neni

    Hi Satish,
    Go to transaction SALE -> Basic settings -> Logical systems -> execute "Define logical system" to create a new logical system -> then execute "Assign Logical System to Client"
    That should solve your problem

  • Logical system Name Change Via Transport

    Hi All,
    Recently we made changes in parallel processing profile customizing table  (/SAPAPO/SDP_PAR) and created entries for Macro Jobs and CIF.
    For Application "CIF Delta Report", Logical system is mandatory and in Dev we gave the APO Dev Logical System Name (AD1XXX). Now when we moved the changes to Quality, expectation was that Logical system name for CIF Entry in the table would change to AQ1XXX - However, it still shows as AD1XXX there. Moreover AD1XXX entry is not a valid entry in Quality System and even when we see Drop Down values for that column (Press F4) - Only APO and ECC Quality systems names are appearing.
    Please suggest how can this logical system name be corrected. One option is running BDLS, but when this TR moves to Production there also we might end up in same scenario (Logical system as AD1XXX instead of AP1XXX) and running BDLS in Production wont be approved.
    Please suggest if there is any other option to handle this.

  • SLD Logical System Name Changes not taking effect in IDOC

    All -
    I've had to change a logical system name in the SLD, everything appears to be okay but new Idocs are still posting with the old LS name - any suggestions as to where to look for the old name would be most appreciated.
    Thanks!

    Hi Dennis,
    After changing the logical system name in SLD have you done "Compare with  SLD" from Service --> "Adapter-Specific Identifiers" for Business system in Integration Directory?

  • Changing logical system name on ECC

    Hi,
    We have made copy of production to our test environment.  Next, we created a number of copies of the test environment.  We now want to hook the copies up to BI, XI etc. where we don't have multiple test environments, which means that a single BI test instance will support several ECC test instances as an example.  This means that our ECC instances will have to have their logical system name changes changed in addition to the obvious SID change.  We have a fairly comprehensive landscape with GRC, XRPM, BI, SolMan, CRM connected to our ECC instance.  What areas of concern would you consider important to test once the logical system name changes are done?  We are looking at the ALE, RFC connections, BI connections.  We included the [help.sap.com information |http://help.sap.com/saphelp_nw04/helpdata/en/33/c823dbaea911d6b29500508b6b8a93/content.htm] in our thinking, but since that did not really explore landscape wide issues....
    Thank you,
    Mike

    Hi
    As prelim checks:
    Check if these changes are maintained in SCC4 client details as well, and check if all the RFCs are working fine.

  • JDBC to Idoc scenario - change of logical system name

    Hi,
    I have a JDBC to idoc scenario that worked. Now i had to change the logical system name from my sender system from ABC_123 into ABC123 in the SLD (Business System - Integration - Logical System name). I did so and also refreshed my Cache.
    Afterwards I started the process, but it failed in the Receiver system. The idoc is correct expect of the partner name. My receiver system expect ABC123 - as I changed in the SLD - but PI send ABC_123.
    If io look in SXI_CACHE - Services my Business System still got the "old" name (ABC_123).
    Did i miss something resp. how can i load the current configuration from SLD?
    Thanks in advance
    Michael

    Hi Michael,
    Again Import the changed logical system in the Integration directory of you PI system.
    And check the scenario (Sender Agreement, Receiver agreement ) what system they are reflecting.
    If they are showing old system then you have to replace the business system in all the scenario.

  • How to change or rename the logical system name T90CLNT090 IN BI 7

    HI Expert's,
    i am really digging for the solution of changing or renaming the logical system name technical name T90CLNT090.
    in our company we are using ecc5.0 with bi 3.5 and ecc6 with bi 7. In BW 3.5 having a connection with R/3 and the technical name of the myself bw source system(logical system) is T90CLNT090.
    In bi 7 also the logical system name is same as T90CLNT090. Because of the same system name(Logical name) it is not active in BI7 and also it's giving error when i am activating the DSO Object as Transfer structure prefix for source system T90CLNT090 is not defined.
    because of this i am not able to create the source system between r/3 also.
    so how to change this source system name for T90CLNT090.
    regards

    Hi,
    Pls follow this OSS note : 325525.
    Note 325525 - Copying and renaming systems in a BW environment
    Summary
    Symptom WARNING: THIS NOTE HAS BEEN REPLACED.  FOR MORE CURRENT AND MORE COMPREHENSIVE INFORMATION SEE NEW NOTE 886102.
    You want to copy and or rename one or more systems (database or client copy). One or more of the systems is a BW system or is connected to a BW system.
    Caution: This note only deals with problems that occur in the BW source system connections. Other problems that occur in the BW environment (indexes) are NOT dealt with. See URL http://www.service.sap.com/bw --> Services & Implementation --> System copy & Migration.
    Other terms BW, source system, OLTP, database copy, client copy, system infrastructure, transport system, connections, RFC connection, trfc, transfer structure, IDoc, ALE customizing, logical system name, system changeability, renaming systems, system copy
    Solution Several scenarios are possible in this environment. Find the scenario relevant to your situation below and execute the steps listed or read the note(s) specified:
    Scenario 1) You do not want to copy a system but only want to rename one (changing a logical system name).
               Solution scenario 1): Execute Transaction BDLS both in the client to be renamed and in the connected BWs or BW source systems. To do this, see Notes 121163 and 369758.
               Check the RFC destinations in all connected BWs/BW source systems as described in Note 524554.
               Reactivate all partner agreements that carry the new logical system name after renaming.
    Scenario 2) You want to copy the entire system infrastructure connected by the BW source system connections (that means the entire system group) by a database copy. SAP recommends this procedure for copying systems.
               Solution scenario 2):
    If you want to rename one or more of the copied systems, then execute Transaction BDLS both in the client you wish to rename and in all the connected BW and BW source systems. See Note 121163.
                        Make sure that an RFC destination exists with the new logical name in every connected BW or BW source system.
                        Reactivate all partner agreements that carry the new logical system name after renaming.
    Change the hosts in the appropriate RFC destinations so that they refer to the correct computer. For this, see Note 524554.
    Scenario 3) You want to copy a single BW system of the group by database copy.
    Scenario 3)a) You only want to exchange the hardware of your system but do not want to rename the system.
                         Solution scenario 3)a): You do not need to execute follow-up work regarding the system connections, except for adjusting the IP address in the RFC destinations of the connected system.
    Scenario 3)b) You want to keep the original system of the copy so that you have two systems after copying.
                         Solution scenario 3)b): See Note 184754.
    Scenario 4) You want to copy a single source system of the group by database copy.
    Scenario 4)a) You only want to exchange the hardware of your system but do not want to rename the system.
                         Solution scenario 4)a): You do not need to execute follow-up work regarding the system connections, except for adjusting the IP address in the RFC destinations of the connected system.
    Scenario 4)b) You want to keep the original system of the copy so that you have two systems after copying.
               Solution scenario 4)b): See Note 184322.
    Scenario 5) You want to import a client copy in a source system.
               Solution scenario 5): See Note 325470.

  • RSA1 - Source system connection : Change in logical system name

    Dear friends,
    Can you please tell me how can i change the logical system name for a source system connection.
    There is no change in source system & source system connection check works well, just we have decided that from current logical system name SID_100 should be changed to SIDCLNT100.
    Can i do this by running BDLS in BW for RSBASIDOC table from SID_100 to SIDCLNT100 ?
    thanks
    ashish

    HI Sunny,
    This is not the same problem, may be similar though..i am not getting a way.
    let me describe u in a bit more details.
    Currently, we have a working source system connection to a system SID_CLT.  there is no change in source system.
    now, can i change this system connection technical name from SID_CLT to SIDCLNT*** .. 
    thanks

  • How to change logical system name

    hi,
    there is no logical system name for business system in sld on integration tab.

    hello all,
    I'm actually having the same issue.  This issue is NOT the popular adapter-specific identifier problem where the business system in the ID needs to be compared with the SLD.  This issue is that the within the SLD on PI 7.0 the Logical System Name of a given business system is not present although the logical system name of the specified technical system does appear.  You cannot change the LSN of the business system since it relies completely on the LSN of the associated technical system.
    I used Jochen's approach before and it worked, but i've tried this again since i'm having the same issue.  Only now it doesn't work.
      i solved this issue by deleting the old BS and recreating it
    Thanks,

  • Change logical system names after system copy

    Hi!
    We successfully installed SAP ECC 6.0 system as system copy.
    All the logical system names of old system have been copied to new system.
    Question
    What is the approach to change the logical system names for new SAP system?
    a) just via tcode SCC4
    b) via BDLS
    c) other tcodes, reports
    Thank you very much!
    regards
    Jürgen

    Hi,
    Go though the system copy guide.
    http://service.sap.com/instguides
    After system copy,
    If you need to change logical system names in the system that results from the copy, change the logical system names as described in SAP Notes 103228 and 544509.
    https://service.sap.com/sap/support/notes/103228
    https://service.sap.com/sap/support/notes/544509
    Before running BDLS to change the logical system name, you have to define the correct logical system name in the new copied system. in tcode BD54.
    - while running BDLS, execute in background.

    Debasis.

  • Changing Default logical system names of a model.

    Hi
        How could i change the

    Hi shah kond,
    you can change  rfc destinations of model in 2 differnet ways.
    firs one: right clcik on project
              from the context menu select propeties
              it will open a dialogbox from that select dynpro references then click on jco references tab
    by using add and remove buttons u can add and remove joc destnations
    2.expand ur model class double click output class.now seelct properties view.there u can change the jco destination
    hope this will use ful for u

  • Changing the default logical system names for adaptive RFC models

    Hello,
    When I create an Adaptive RFC model the dialog that asks me to specify the model name, package, source folder, etc. has default values in the "Default logical system name for model instances" and "... RFC metadata".
    I know I can type in another name there but I'd like to change the default name to something that fits our naming conventions. Can I change that? If so, can someone tell me where?
    Thanks in advance!
    David.

    Suresh,
    Thank you for your response. However, that is not what I was looking for. Sorry if my post was not clear.
    I knew that I could change it AFTER the import. I also know that I can type in something else besides the default DURING the import.
    What I am asking is if there is a way to change some configuration setting so that the 'default' that comes up in the drop down DURING the import is something different than what comes 'out-of-the-box' with NWDS.
    Hope that clears up what I'm looking for.
    David.

    Hi,
    Goto tcode SCC4.
    Switch to change mode. (System will prompt that this table is cross client. Continue)
    Select your client (in this case 200). Click on details button (next to change mode button)
    Enter the proper logical system name in Logical system field.

    I want to Use my IDES SAP ERP 7.0 as my BI system for training purposes,when iam executing the transaction RSA1 in the system it is giving message
    "Logical system name has been changed for
    system"
    I Have changed the entries in table "RSADMINA" and maintained the Client no as 100 (My base client for BI) which i have copied from 001.
    When iam executing the Transaction RSA1 in 100 it is giving above mentioned error ,whereas in 001 it is working fine.
    Please Help . ..
    I tried to change the system logical name by "bdls" but it doesnt worked........

    Hi Deepak,
    Check the entries in table RSLOGSYSMAP (this is meant for correct conversion of logical system names for tansports).
    You can easily maintain the entries using tcode RSLGMP.
    Hope it helps.
