Homogeneus system copy error

Question

Hi all,
I have already functionally a SAP instance PRD ECC 6.0(ABAP only) on server with Windows Server 2008 R2 X64 and Database MSSQL 2005.
I tried to make a Homogeneus System Copy with Backup/restore method on same server but i have some errors.
I made the Backup of the MSSQL PRD Database and I saved it to another partition.
I created the QAS Datafiles on SAP DB partition and i loaded The NEW DB on MSSQL. For new Database QAS i selected SQL_LATIN1_General_CP850_BIN2 for collation option.
I launched the SAPINST procedure and I selected the Homogenes System Copy Backup/Restore option.
I selected the existing QAS DB that i already restore on MSSQL SERVER and then I pressed NEXT button.
Now I have this error:
Administrator@WIN2008SAP2: Input Error
User tables belonging to the dbo schema were found in the database QAS.
SOLUTION: You can only install an SAP system in a database with no user object belonging to the system schema dbo.
If there already is an SAP System in the database(MCOD), or you install a Java ADD-in, you might have to convert the existing system to its own schema, or contact your SAP support.
I looked on PRD System and it is a MCOD system. What shoud I do now? I did the wrong steps for HSC for MSSQL????
Any help appreciated, Thanks
M.C.

Please check which tables exist in your SAP database with schema dbo:
select name from sys.objects where schema_name(schema_id) = 'dbo' and type = 'U'
If this shows only the tables sysdiagrams and dtproperties:
This error can be caused by the existence of the table sysdiagrams.
This table is created by monitor operation at the SQL Server Management Studio.                                           
It can be deleted without risks as described below:                             
   drop procedure sp_upgraddiagrams                                      
   drop procedure sp_helpdiagrams                                        
   drop procedure sp_helpdiagramdefinition                               
   drop procedure sp_creatediagram                                       
   drop procedure sp_renamediagram                                       
   drop procedure sp_alterdiagram                                        
   drop procedure sp_dropdiagram                                         
   drop function fn_diagramobjects                                       
   drop table sysdiagrams

P.S.
The table will be created again automatically when a new Diagram is created in object explorer.
P.P.S.
Newer sapinst shouldn't encounter this problem anymore, the check in control.xml was changed to consider this table as 'harmless' (as it already does with dtproperties).
