# Node Submission Rules

> This article explains the purpose of node submission rules and how they are triggered, including the difference between task completion execution and node completion execution. It also covers how to apply these rules through actions such as Accept and Decline, with links to related documents on Formula usage and service guides.

Node submission rules use formula validation to determine whether a user can perform an action when submitting a process or when an approver handles a process.

## Trigger Methods

<Note>
  **Difference between task completion execution and node completion execution**:

  If an approval node has multiple approvers, each approver counts as a separate task, while the node itself remains a single unit.
</Note>

### Task Completion Execution

As shown in the figure, this rule is triggered when the actual action on the manual node is "Accept".

Similarly, "Decline", "Save", and "Return" can be configured in the same way.
