You can use the <b>Create Custom Business Process Event Task Definition</b> and <b>Create Custom Business Process Type</b> tasks to create custom business processes for workflows specific to the needs of your organization and for which Workday doesn't provide delivered business processes.

You can also use:

-   The customBusinessProcessConfig REST API to create custom business process types.
-   The customBusinessProcess REST API to create and launch custom business process events.


You can use these tasks or the REST API to define:

-   The pages used for each event action. Example: Approval, Revise, and Event Details.
-   The available event actions.
-   The target business object. The only target business object currently supported is Worker.
-   The initiating allowed action. Example: You can use a use custom task to initiate workflow in a custom business process.
-   Worker-based effective dated custom objects.


Business Process Administrators can use Workday to:

-   View the custom business process type and configure the business process security policy.
-   Create or edit the default business process definition.
-   Build custom reports based on the Action Event business object.


When creating or editing the default business process definition, Business Process Administrators can:

-   Configure these steps:

    -   <i>Initiation</i>.
    -   <i>Action</i>.
    -   <i>Approval</i>.
    -   <i>Integration</i>.
    -   <i>Service</i>.
    -   <i>Edit Additional Data</i>.
    -   <i>To Do</i>.
    -   <i>Checklist</i>.

-   Configure condition rules, notifications, and custom reports based on the Action Event business object.


If you enable approval and associated approval actions, Approvers can:

-   View any data submitted within a custom business process event on the approval page.
-   Send back a custom business process to the Initiator for revision.
-   Deny a custom business process.


Business Process Administrators can also cancel a custom business process event.
