This part of the new window, along with its supporting procedure, shows you can make the same tables part of more than one ProDataSet, as long as each ProDataSet has its own unique set of buffers for those tables. You can fill commonly used data just once, on the server or on the client as needed, and then subset it in this way without any need to copy the data to each new view of that data.
In the next section, you will extend this procedure to show an alternative to this, namely, how to create a new ProDataSet that actually uses an existing one as a Data-Source, and creates new temp-tables with only a subset of the columns in the original ones.
