Configure time period categories

You use time period categories to manage the data structures of different kinds of time period definitions. You can create new categories, and update or remove existing ones.

Category types

All categories fall into a set of types defined in globallist timeperiodCategoryTypes based on the codes table. The out-of-the-box types are described in the following table. You can configure the types to suit your needs.

Type	Description
Maintenance Window	Maintenance period.
Neutral	Information period.
Freeze Period	Blackout period.

Category workflows

Each category has an associated workflow, which is created for the timeperiodDefinition table. Before creating a time period, make sure you have already created a workflow for it. For details, see Configure a time period workflow.

Category configuration

To create a new time period category, follow these steps:

Click Time Period Management > Configuration > Time Period Categories.

The Time Period Categories search form opens.
Click New.

An ID is automatically assigned to the new category.

Complete the following fields.

Whether a user can use a category or not is also dependent on the Allowed Categories setting in the user's Security Role. For more information, see Time period security areas and roles.
