The JS7 - Variables are used to execute the job using different parameters on the order or on a Workflowparameterize the execution of jobs in a workflow.

If the job resources with this the variable are assigned attached to the whole workflow or on the jobs.workflow, the variables will be available for all the jobs in the workflow.
• As an In Order Variable: You can declare variables with a workflow and assign or modify values when adding an order to the workflow while adding an Order. The default and require value is assigned to the order.

The folder 03_VariablePassing contains the workflow based on the variable passing. You can add the order from the action menu of the workflow and from the history you can review the detailed information about the workflow.

Workflow

The 03_VariablesPassing folder contains workflows used to pass variables.  In the job script, the two variables are used with the name BOOKING_CODE and FLIGHT_DESTINATION.  The value for the BOOKING CODE does not change during the whole workflow.

The variables are not editable during adding the Order as they declared within the job script.
