Choice lists are one of the basic input elements available in Service-now.com. They are very simple to personalize and add or remove any options you need for your application. Something I see fairly often is the need to use the EXACT same choices in different tables that may not be directly related as extended database tables. Another scenario is where you have a choice list defined on a standard field and you want to use that same field and its choices in a service catalog ‘Select box’ variable. Service catalog record producers often have this requirement. In these cases, you may be tempted just to manually re-create the entire list of choice list options for the new field or ‘Select box’ variable. As long as the lists are the same, you can save yourself some setup time (not to mention the ongoing headache of maintaining the same information in 2 places) by making use of the ‘Choice table’ and ‘Choice field’ options.
