SQL Password Changed.SAP DB List Empty

Hi All,

          I changed The Password of sa User in SQL Server.

          Then I logged into SAP Site User Portal,selected the SQL Server Authentication ,Click Edit Given Username : sa and Entered New Password and Saved.

          Refreshed the Databases and Logged out.

          Now If I Open SAP the Databases are Initially Listed out but not logging In ....Error "Invalid Username )r Password"but the Password is Correct Only.

     Now I click the Refresh Button and The Database List is Empty.

If I change the Old Password in SQL Server and updated the Same in Site User Portal Also..Now the Databases are Listed and Logged in ...In SAP B1

     so if i change the Password in SQL Server,it is not reflecting in SAP even though Updated in Site User Portal.

Please help in this Regard
