I'm working with ArcGIS 10.2 for Desktop and OS Windows 7.
I need to set numeric vales from Zero back to NULL, but I can't from the field calculator.
I'm working with a vector file and I need to display NULL in one column that shows 0 (Zero) as default value.
I am adding the error messages that he received

Error at bottom, translation: The values of the selected column can not be set to null because the field in the database is defined as "Not Null".
