A code value is a unique value, such as a business term, code, or lookup value. Code values are organized into code lists. Each code list contains code values from a single source application or industry standard list. You can add code values or import code values into a code list.
You can add or edit code values in a code list by locking the code list or without locking the code list. When you lock the code list, you restrict other users to make concurrent edits to the code list. When you don't lock the code list and edit a code value, other users can edit other code values in the same code list. The edited code value is locked for other users until you publish or discard the draft code list or an approver approves the updated code list.
Later, you can create crosswalks to map code values in a pair of code lists. Crosswalks provide a way to translate between the different code values each application uses for a business term.
