Managing data fields

You can add, change, or delete fields from the list of exposed data fields in your roster, queue, or event log definition.

About this task

Exposing a field makes it available for use in a search filter or when defining an index. Adding a data field to the list of exposed fields does not create the field. The workflow author creates the data field. In the same way, removing a field from the list of exposed fields does not delete the field, but it makes the field unavailable for the listed uses.

Important: Exposing workflow fields adds to the system overhead, both in space and performance. Additional performance impact can occur in the following cases:

Event logs: Exposing workflow fields affects the transmission of information to Case Analyzer, as well as the size of the Case Analyzer store and the performance of Case Analyzer.
Workflow rosters: Exposing workflow fields that change frequently can degrade performance. In addition, all fields that you expose are displayed by default to the user. If an exposed field does not exist for a particular work item, a default value is displayed.
