# Node Connections

> This page explains how to configure node connections in the Premium workflow designer, including the steps, methods for configuring line execution rules, and usage examples. Control workflow routing rules by setting conditions or using code mode to ensure the workflow runs according to the intended logic.

Node connections are the lines that link nodes in a Premium workflow. They define the routing rules between nodes.

## Steps

1. Open the Premium workflow designer.
2. Select two nodes that have been configured but are not yet linked.
3. Select one of the nodes, then click an arrow in any direction to connect it to the next node.

| **Rule**                   | **Description**                                                                                                                                                                                                 |
| -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Configure by condition** | Use form fields and system fields to set condition rules. The workflow proceeds along this connection line to the next node only when the configured conditions are met.                                        |
| **Code mode**              | Enter a parameter value directly or use a Groovy expression.<br />**Note**: The Default value is **true**, which means the workflow proceeds directly to the next node along this line under any circumstances. |

## Usage Example

When the value of the form component "Reimbursement amount" is less than 1,000, the workflow routes to the "Supervisor" for Approval. When the amount is greater than 1,000, the workflow routes to "Finance" for Approval.

As shown below, when the reimbursement amount is 500, the workflow routes to the Supervisor for Approval.

When the reimbursement amount is 2,000, the workflow routes to Finance for Approval.
