NONE > Required on input and Zero > Required on input

Select a value from the Required on input property list.
Yes
If the data object is NONE or Zero, the map uses the value in the Special Value property when it validates the item in the input.
No
Do not use the value in the Special Value property. No special values or input requirements are defined when data is NONE or Zero.

When the map builds the item in the output, the item might be either the value in the Special Value property or the default value for NONE or Zero. For example, if an item contains all pad characters and no actual data, the default value for NONE is used when that item is built in the output.
