Ensuring Name Uniqueness for Options and Choices
You can use two preferences to control the uniqueness of the names for options and choices:
The Option name uniqueness preference specifies whether the name for the option should be unique within:
The product or library where the option was created (this is the out-of-the-box setting)
The hosting organization for the product or library where the option was created
The entire site
The Choice name uniqueness preference specifies whether the name for the choice should be unique within:
The option for which the choice was created (this is the out-of-the-box setting)
The product or library where the choice was created
The hosting organization for the product or library where the choice was created
The entire site
You need to be a Site Administrator to set these preferences.
