The remote server is the model containing the target tables of the external shortcut or replica. The remote server is defined using a data source in the proxy tables model; this data source provides access to the remote data on the server.
Note: the same data source can contain information for several models that share the same remote servers.
When you attach the ProxyTables extension file to the model containing the proxy tables, a new command is added to the contextual menu for the physical data model item. The target models must be open in the workspace in order for the command to build data sources for them.
