Overriding extended data elements of parent event definitions
A child event definition automatically inherits the extended data elements of its parent event definition. However, in the event definition editor, you can choose to have your child event definition override one or more extended data elements of its immediate parent or any higher-level parents in the same inheritance hierarchy.
To override extended data elements of parent event definitions:
Procedure
- Open your child event definition in the event definition editor.
- In the event definition editor, click the Add
Extended Data from Parent icon
. The Select Contents window opens. By default, the window box shows the name of the immediate parent event definition and all of its extended data elements that are not currently overridden in the child event definition.
- If you want to show the names of all parent event definitions in the same inheritance hierarchy as well as all of their extended data elements that are not currently overridden in the child event definition, select the Show all parent events check box.
- In the Select the contents to add list, select one or more extended data elements of one or more parent event definitions that you want to override in your child event definition. If you are overriding an extended data element that contains nested child extended data elements, you can only select the parent extended data element in the Select Contents window. Although both the parent and its child extended data elements will be added to your event definition, you can later remove any of the child extended data elements that you do not want and they will be transparently inherited from the parent event definition.
- Click Finish. The overridden extended
data elements are added to the child event definition. The overridden
extended data elements are flagged with the This extended
data is inherited from the parent event definition symbol
.
What to do next
After you have overridden some extended data elements of one or more parent event definitions, you will probably want to change the values of the extended data elements as described in the topic "Changing extended data element values."
