If multiple PCs are accessing the meta repository there needs to be a standard naming convention such that all PCs use the same ODBC Source name.
TIP: The same ODBC source name must be used on all PCs that use this connection. All users need to log into Data Warehouse Designer using the same ODBC source name as the ODBC Source on the data warehouse connection. If the ODBC source name on the data warehouse connection differs from the log in ODBC source name, you will not be able to drag and drop existing data warehouse objects to create new ones.
