Hi Friends,

I have created a System Object in portal" MDM_System_alias" and want to retrieve Alias from webdynpro java view. Based on this this object i have to retrieve the UserMapping of 'userID' and 'Password'. and 'Server name' and 'Repository' and other MDM server properties.

Could you please provide your valuable pointers.
