You can define a default completion 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 completion deadline is reached.
You have defined a default completion 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 completed before the deadline is reached.
