-The Set Variable task allows you to create workflow variables or update them with new values. The task is used to track a shared variable at the workflow level across tasks, and these variables can be accessed or overwritten in any subsequent task in the workflow.

+Variables can be initialized and updated at any point in the workflow. Once a variable is initialized, it can be accessed in any subsequent task using the expression `${workflow.variables.variableNameHere}` (replacing variableNameHere with the actual variable name). Initialized values can be overwritten by a subsequent Set Variable task.

+## Limitations
+
+The scope of the Set Variable task is limited to its workflow. An initialized variable in one workflow will not carry over to another workflow or sub-workflow and will have to be initialized again using a new Set Variable task. In some cases, you can consider setting up global [environment variables](/developer-guides/using-environment-variables) to manage frequently accessed variables across workflows.
