It’s commonly employed to ensure synchronization of data and communication with remote services is completed before advancing to the next node. By double-clicking the Wait node, you can specify the **amount of time** and **the time period** (minutes, hours, and days). The minimum time value is 1 minute, and there is no maximum limit. ![](https://cdn.document360.io/08a474ca-8fb4-4c3c-9cd8-665242086cd3/Images/Documentation/wait_node.PNG) You can monitor workflow executions currently paused by a Wait node under the [Running workflows tab](/v1/docs/workflow-logs#running-workflows). ### Wait output | ![](https://cdn.document360.io/08a474ca-8fb4-4c3c-9cd8-665242086cd3/Images/Documentation/then.PNG) | The **then output** serves as the point where all subsequent workflow nodes should be connected. | | --- | --- | **What happens if you change or inactivate the workflow?** - Inactivation: If you [inactivate](/engine/docs/workflow-configuration#activate-and-inactivate-a-workflow) the workflow, new runs will stop, but **workflows that are already waiting will continue**. - Impact of changes: Workflows run based on a snapshot taken when they start. Any **changes you make will only apply to new runs**, not to workflows that are already waiting. --- ## Variable assign The Variable assign node stores information as **transport data in the subsequent nodes** until the workflow is completed. Variables are useful when a value is only relevant during the execution of the current workflow eliminating the necessity to store it for a longer term in an entity attribute field. - Set the **name** of the new variable This name is used to reference the variable in subsequent filters and actions. - Define the **value** of the variable Use volt expressions for advanced-level calculations of variable values. ![](https://cdn.document360.io/08a474ca-8fb4-4c3c-9cd8-665242086cd3/Images/Documentation/variable_assign.PNG) *These examples illustrate how the date of the purchase can be calculated and stored in a variable.* ### Variable assign output | ![](https://cdn.document360.io/08a474ca-8fb4-4c3c-9cd8-665242086cd3/Images/Documentation/variable_assign_node.PNG) | The **success** output serves as the point where all subsequent workflow nodes should be connected. | | --- | --- |
