DB connect source system creation in BI

Question

Hi,
I would like to create a DB connect source system to an external MSSQL 2005 database in RSA1.
The external MSSQL 2005 database is setup using Windows Authentication mode.
Question: Which user actually should I specify when creating the source system in RSA1? or which user should I assign the db_ddladmin role in the external MSSQL database?
Many thanks,
YJ.

Hi,
Please note the following with regard to the user:
To avoid problems loading data, proceed as follows:                   
1. Create a special login for the extraction. You should add this login to the db_ddladmin database role in the 
corresponding database. This generates a similar DB user at database level. The user you use must have the 'CREATE VIEW'
authorization at least.  This is contained in the role mentioned above.
2. For the extraction, you should only use DB views that were  created under this DB user. (refer also to type conversion, naming       
convention and so on)                                                    
3. Assign the necessary authorizations (SELECT at least) to the  selected user in the source tables, or the columns of these tables.      
4. Use the specially created login in the logon information when you set up the DB source system in BW.   
You will find much more detailed information on how to setup the connection and known problems and issues in the
attached note 512739.
Best Regards,
