Key Reference indexing

The Key Reference indexing feature operates similarly to automatic indexing. The Key Reference feature is useful for automatically populating the index information, changing the index information frequently, or both.

Note: When you modify document indexes that are created by using the Key Reference feature, updating index field data on one document might automatically update data in the same field on other documents with the same key index value.

When you modify a data field value on an existing index record, ApplicationXtender finds all index records with the same key value and makes the same change to those records.
When you modify the key field value on an existing index record, ApplicationXtender modifies only that document; all other documents having the original key value remain unchanged.

EXAMPLE: Key Field Versus Data Field

Assume that for the HR application, the ApplicationXtender system administrator has configured Employee ID as the key field and Employee Last Name as a data field. If you modify the Employee ID field for an index record, the other documents with the same employee ID are not affected. However, if you modify the Employee Last Name, the value changes in all other documents with the same Employee ID.

Note: The Auto Index or Key Reference functionalities are available for indexing only if the ApplicationXtender system administrator configures the ApplicationXtender applications with fields enabled for Auto Index or Key Reference.
