In this workflow we select one car maker and type of drive wheels. We then move to a CASE Switch to process differently the groups of data. If you select "alfa romeo" as the car maker and 4wd as the type of wheel drive, the switch branch will have no data. The Empty Table Switch node then disables the data and prevents the execution of subsequent nodes with no data, thus avoiding errors and warnings.
