Which node is used to flow a purchase order for approval or disapproval based on cost?

The Task Node is crucial for managing the flow of actions and decisions within a workflow, particularly in the context of purchase order approvals. In this case, when a purchase order must be evaluated based on its cost, the Task Node is employed to facilitate the decision-making process. It can be designed to present the purchase order for review, enabling stakeholders to approve or disapprove the order based on the specified cost criteria.

In a workflow, the Task Node encapsulates the activities that need to be executed, such as sending notifications, executing specific business rules, or conducting checks on the purchase order data. This allows for a structured approach to handling purchase orders, ensuring that the necessary evaluations and approvals are systematically addressed.

Other nodes serve different purposes: Interaction Nodes are used to handle external interactions or communications, Wait Nodes pause the flow until a specified condition is met, and Sub-process Nodes encapsulate a separate workflow that can be executed independently. Each of these nodes contributes to the overall workflow, but for the specific task of assessing a purchase order for approval based on cost, the Task Node is the most appropriate choice.
