Once a catalog item has been requested, the mechanism that determines the approvals and tasks that are triggered in the application is the flow12.
A flow is a graphical representation of a business process that consists of one or more actions, such as approvals, tasks, notifications, scripts, etc., that are executed based on certain conditions and triggers12.
A flow can be associated with a catalog item to define the fulfillment process for that item, such as who needs to approve it, what tasks need to be performed, and what notifications need to be sent12.
A flow can be created and managed using the Flow Designer, a low-code development tool that allows users to design and test flows without writing any code12.
A flow can be activated or deactivated, versioned, and published to make it available for use12.
A flow can be monitored and debugged using the Flow Execution Details and the Flow Logs12. Reference:
