Mar 30, 2011 4:05 PM in response to A. Richardsby henkrek,So it's good practice to always choose a value for the fields you might want to use for filtering.
Most of my lookups contain the value 'Undefined'. So in case I can't or don't want to specify a value for a certain field I'm giving it in some occasions the value 'Undefined'.
The value 'Undefined' also comes in handy when you want to trigger on the change of a certain field. While it's impossible to reset the field to the (non)value [NONE] a reset to 'Undefined' makes it possible to re-run the modify subscription with the trigger on the same field when needed.
