Changing Default logical system names of a model.

Hi
    How could i change the
     Default logical system name for model instances:
     Default logical syatem name for RFC metadata:
    values for existing model? without recreating the model.
     Thanx

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.

Default logical system names for application and metadata in models.

hi,
I have a dbt in web dynpro java. When we create a model, we give the logical system names. When our developement is over, do we have to change these names because in test system and subsequently production system, the backends will be oviously different than developement ?
how do we change them and re import after changing? in abap we cant change our code in test and prod systems right so how is it in web dynpro java ?
thanks

Hi Jeschael,
thanks for the reponse.
When I create the model, I give the default logical system names and on the next screen I give the
ip address of the backend system, client , login, password etc
Even though the logical system names wud be same in Dev, Test and Prod systems, the ip address, login password is different so how do I give it ?
thanks

Finding "Default Logical System Name Model Instance" in DC Project

Hi,
While Creating an Adaptive RFCModel, one defines the
Default Logical System Name for Model Instance & the
Default Logical System Name for RFCMetadata.
In which file can I find these settings at a later stage in the Project File Structure.
Ofcourse, I can view them in the WedynproContentAdministrator under the Jco Destinations.
But is there anyway to access them in the NWDS?
Regards
MK

Hello MK,
You'll find the Logical System Names of the JCo destinations in the file ".wdproperties" under the project structure.

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.

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

Change of logical system name

Dear Experts,
I have following situation in ECC 6 EHP4 system:
a system copy of PRD system was peformed on QAS. POst system copy BDLS was NOT run, and logical system of QAS client was maintained manually.
Now client 300 in QAS has logical system as QASCLNT300 (after copy it was PRDCLNT300). The problem is that many accounting documents still point to PRDCLNT300 and hence can not be viewed now since log sys is QASCLNT300 now.
I can not run bdls now bcoz for BDLS target logical system should be new. Also for last few months new accounting docs has been generated for QASCLNT300.
Is there any way around? pls suggest
-Thanks,
Richa

This is a situation , where you cannot run BDLS now and you face issues with accounting docs .
As far as I feel , you will have have to redo the system copy and run BDLS again. The logical system name should never be maintained manually in SCC4.

Is it possible to change the Logical System name in ID

Hi,
I am doing a file to Idoc scenario. My requirement is to overwrite the logical system name, which is set in SLD for sender (system). Is it possible to overwrite it in ID or in mapping somewhere.
Thanks,
Dehra

Hi Dehra,
Go through the below help file of SLD. It will give you information regarding logical name as well:

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.

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.

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?

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.

Scm:Logical system Name is changed. cannot access BW system.

Hi,
plz help me to solve thi problem.
SCM : Logical system Name is changed. cannot access BW system. system throw an error "Logical System has changed".

Hi Raj,
We can create the Logical system name in SALE or BD54 and we can assign the same logical system name in SCC4 for that particular Client.
If you want to change the logical system name after a client copy or System copy. Use BDLS.
Thanks,

Logical system name to be updated while client copy--URGENT HELP REQUIRED

Hello All,
I have a query regarding the "Logical System name" updation during Client copy.
When we make a client copy(SRM Masters) for the Production system(SRM),the Old Logical system name for backend(which is attached to the SRM masters) gets copied to the new Client (Copy) which needs to be updated.
There is a std transaction BDLS through whcih w e can change the current Logical system name to a new one but this seems to work fine for System copy but not for Client copy.
So when i make a client copy of SRM masters for Production system,is there any other std way wherein i can change the "Logical system name " for the backend or do i have to write a CUSTOM program wherein entries for the Backend Logical system name in tables like CRMMLSGUID will be updated with the new Logical system name?
Any help on this is appreciated.
Thanks & Regards,
Disha.

Disha,
Yes, I did it twice and it worked fine.
The R/3 GUID is sent by the OLTP system (R/3) in R/3 message header.
SRM checks this GUID in CRMMLSGUID table.
If is not the same one, then replication process fails.
The only solution I found was to delete this entry. It is automatically recreated with the new GUID with the next replication, with FM CRMT_OLTP_LOGSYS1, called in BAPI_CRM_SAVE.
Look at OSS note 588701 & 765018 for deletion of CRMMLSGUID.
The issue is exactly ours: around system/client copy.
In an CRM environment, this is more critical, because we make a huge use of the middleware. But in our case, and especially after system/client copies, we can go, even if SAP does not guaranty anything, because we don't care about "old" replicated data (I don't care about old BDOCs, that should even be deleted after processing).
We have to take some risks sometimes...
