2.6.2 Marking the Field as Unique

Check against 'Unique' if the field that is being defined has to be unique. Consequently,
  • If the usage allowed for the field is 'Product', the new field will be unique across modules
  • If the usage allowed is 'Function Id', it will be unique for the particular function id i.e., if you have specified a function ID, the new field can be used only in the specified Function ID screen).
