Overview Example See Also ## Overview An update map shows mappings for required, optional, and key elements. In an update map, optional elements are displayed with a question mark, and key elements with a key symbol. A key element is usually required. ##### Optional and Key Elements in an Update Map If you remove a mapping from a key element, it becomes disabled with a warning icon . ##### Mappings to LINE_ID and PROD_ID Deleted Removing a mapping might also cause create, update, or delete procedures to become disabled . However, you can correct either of these conditions, by handling unmapped required values. ## Example If you need to remove a mapping, you can do so in either the update map or query map. To remove a mapping in the update map: Click the Update Map tab. Right-click the mapping line, then choose Delete. If the element becomes disabled in the update block on the left, resolve it. To remove a mapping in the query map: In the Query Map tab, right-click the mapping, then choose Delete. Handle any required unmapped values in the update map. ## See Also ##### Concepts Understanding Update Maps ##### How Tos Change a Mapping Revert Customizations Handle Unmapped Required Values
