>? parameterized view the view in DE has been set for nodataonload .t., If the set of records coming from a table that has 50,000 records. My question, Is the set of records I have asked for the only records traveling the network or did all 50,000 records come over and only display the records I ask for.

If the view is optimizable, then the entire index is sent over the network. That is processed to determine which records are to be returned and then only those records are retrieved over the wire.

If the view is not optimizable then the entire table is sent over the wire for processing.

HTH.
