Description: once an NSN is in use we cannot update required information. Recommended: give us a method to change requirements. Example: if Date of manufacture is no longer required it should delete Date of Manufacture data on update. If an item that was not required becomes a requirement, it should fill that data with a default place holder "UNKNOWN" until that data can be updated. Mission Critical: Highly important. If I make an error and items are received before it is found I am stuck having to enter unnecessary data or can't add required data. Benefits: time savings and accuracy Users: all users.
