You have opened the Process Development perspective in the SAP NetWeaverDeveloper Studio and have expanded your project in Project Explorer view.
You have created a task.
A start deadline indicates by when the task processing must have been started. The task must be started by users before the deadline is reached, otherwise compensation actions are triggered based on the nature of the deadline (critical or non-critical).
By default the task has no start deadline. You can define a default start deadline by defining an offset related to the task activation time or by using an expression to evaluate absolute time of type xsd:dateTime.
You have an option to set the task to an error state when the start deadline is reached.
You have defined a default start deadline for the task. You can select the Raise critical exception when deadline is reached checkbox if you want to raise a critical exception when the task has not been started before the deadline is reached.
