ERROR : You can only work in client 900

Question

Hi,
There are 2 clients in the BI environment.
Client 200 & Client 900.
Client 900 is used for testing.
Client 200 is used for development environment.
We are able to use Client 900 without any problem.
But when we login in client 200 and execute t-code RSA1"
following error occurs.
"You can only work in client 900
Message no. BRAIN009
Diagnosis
Your SAP BW system can only operate in client 900.
Procedure
Log on in client 900."
Can someone suggest solution for this.

hi,
check oss note 522569-BW: Working in several clients (especially APO 4.x/SCM 4.x)
and thread
Re: Is it posible to work with multiple clients in BW?
hope this helps.

Symptom
You cannot work in several clients in the BW system or in a system that uses BW as a basis (for example: APO Demand Planning).
Other terms
MANDT, client, source system, APO, SCM, ERP, Bank Analyzer
Reason and Prerequisites
In BW, master data IDs and dimension IDs are taken from number ranges. The BW objects against which the number range intervals are client-specific are cross-client objects. As the IDs must be unique, these may only be determined in one client. This means that BW can only operate in one client.
The BW objects are cross-client. They can be accessed and changed to the same extent in all clients. BW is displayed identically in all clients. In particular, there is only one Myself source system as this is used to generate the change log for ODS objects. Therefore, when the Administrator Workbench is started, the system checks to see whether you are working in the same client in which the Myself source system was created.
Some extractors from the APO system only work in the client in which the data was created (this is due to the fact that the LiveCache is used). As the Myself connection does not change the client, the extraction of this data must be started in the same client in which the APO data was generated.
For more information about client-dependencies for SAP APO and SCM 4.x, refer to the paper "SAP APO 3.x & SAP SCM 4.0 Multiclient Capabilities" in http://service.sap.com/scm -> mySAP SCM Technology -> "Installation, Upgrade, Migration, System Copy, Client Dependencies". The direct link for the paper is: http://service.sap.com/~sapidb/011000358700006688312002.
Solution
Particularly in SCM/APO it can make sense to use several clients for BW in the SCM/APO system, because the SCM/APO Customizing is client-specific. CAUTION, this note only applies to SCM Releases as of 4.0. For Releases below SCM 4.0, see note 384057.
In SCM as of 4.0 (BW 3.0), it is possible without a BW modification to log on in several clients and to also use the BW functions in these. In addition to this note, you must also take some restrictions and other information into account. This information is maintained centrally in the paper mentioned at the beginning of the note.
BW 3.0B
           Import Support Package 2 for Release 3.0B (BW3.0B patch 02 or SAPKW30B02) into your BW system. The Support Package will be available once Note 493971 "SAPBWNews BW 3.0B Support Package 02", which describes this Support Package in more detail, has been released for customers.
Proceed as follows:
The default client must still appear in the BWMANDT field in the RSADMINA table. Under no circumstances must this entry be changed. Otherwise it may be impossible to use the data in all InfoCubes and all master data tables. Numbers are taken and only created in this client.
Using transaction SM59, create an RFC destination for this default client with the following attributes:
RFC destination (name)
Connection type:         R/3 connection
Client:                  Default client from the RSADMINA-BWMANDT table
The connection must have a password or it must be set as a Trusted System. It must be possible to log on using this connection without additional passwords being requested.
Enter this RFC connection in the BWMANDTRFC field of the RSADMINA table.
When you work in different clients, you must take the following restrictions into account:
BW releases lower than 3.5
BW does not support the connection of new source systems (also file source systems) outside the BW standard client. Only one "myself" source system can be created.
It is considered possible to connect a client other than the BW standard client to an external BW as a source system. Although you can do this using note 609167, this involves restrictions that are mentioned below in the "BW Release as of 3.5" section.
Proceed as follows if you want to upload data into your new client (also ODS update and file source systems). This is not valid if note 609167 has been implemented):
                     In your new client for all source systems, from which you wish to upload data into non-BW standard clients, create partner connections as an IDENTICAL copy (including names) of the partners in the BW standard client.  If you are setting up the new client for the first time, you can use the client copier (transaction SCCL).
                     Create the BW background user (generally, BWREMOTE) with the S_BI-WHM_RFC and S_BI-WX_RFC profiles. Make sure that the name is the same as the name in the BW standard client.
BW releases as of 3.5
BW does not support the connection of new source systems (also file source systems) outside the BW standard client. Only one "myself" source system can be created.
The Administrator workbench can only be called in the BW standard client.
You cannot upload data into a client other than the BW standard client.
                    As of BW 3.5 with PI BASIS 2004.1 or higher, you can connect another source system besides the BW standard client as a separate source system to BW (extraction from another client within the system), provided the BW standard client and BW background user have been entered in the Myself destination. See note 538052.
Authorizations/roles
Like users, authorizations are also client-specific. If you work in several clients, you must ensure that the necessary authorizations and roles exist in the other clients.
Client copy
No client copy may be performed in the BW standard clients. This would destroy the versions of the number range intervals and thereby make the BW data inconsistent.
