1.	What is dictionary override in ServiceNow?
Answer» Dictionary OVERRIDES allow for overriding various field PROPERTIES in an extended table. Consider an example of a changing table that is extended from the task table. There is a status field in the task table which is set as read-only. If you USE this field in CHANGE form, it will be in read-only mode. By using the dictionary override, we can ALTER this to non-read only.
