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

Question

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.
