Hi
I have reports based on Our DB, wich I save on Enterprise, the Info View user runs the reports, it asks the password at database logon, inputs the User ID, the Password, and the report with data appears.
Server Description Our DB Server
Database Type OLE DB (ADO)
User ID aaa
Password ****

Now I have a report based on .xml with I saved on Enterprise. When the Info View user wants to run the report, it asks as well
Server Description xml
Database Type ADO.NET (XML)
User ID
Password

I have no ideea what User ID, Password to input or where could I set it. Can you help, please?
