Changing extended data element values in event definitions

In the event definition editor, the Properties view displays values associated with extended data elements. You can use the Properties view to set or change the values.

This topic describes how to change extended data element values that are accessible from the Properties view.

If you want to learn how to specify data types for extended data elements in the Viewer page, see the topic "Specifying data types of extended data elements."

To change extended data element values:

Procedure

1. In the event definition, select the extended data element for which you want to set or change values.

2. Click the Properties tab to open the Properties view.

3. If the data type of the extended data element is not an array, then position your cursor in the Default value field and type in a default value. This field is optional. The default value will be used during content completion for an event that is missing a required extended data element. If you are overriding an extended data element from a parent event definition and you do not specify a default value, the default value will be inherited from the parent event definition.

4. If the data type of the extended data element is an array, then optionally complete the following steps:
   1. Beside the Default values field, click the Add button to add a value variable to the Default values field for the first element in the array.

   2. In the Default values field, ensure that the value variable is selected and then type in the default value that you want to use for the first element in the array.
   3. Repeat the previous two steps for each element in the array. The default values will be used during content completion for an event that is missing a required extended data element. The Default values field is optional. If you are overriding an extended data element from a parent event definition and you do not specify a default value, the default value will be inherited from the parent event definition.

5. If the extended data element has a data type of noValue, you can optionally specify minimum and maximum occurrences by completing one or both of the following steps:

   1. In the Minimum occurs field, type the minimum number of instances of the extended data element that must appear. This field is optional. The default value is 1.

   2. In the Maximum occurs field, type the maximum number of instances of the extended data element that can appear. If you want the maximum number of instances to be unbounded, you can type unbounded in the field. This field is optional. The default value is 1.
   If you are overriding an extended data element from the parent event definition, any values specified in the Minimum occurs or Maximum occurs fields will override the values specified in the parent event definition.
