You can create a Workflow, in which deadline on the downstream task can be specified by the upstream task. It makes easy to tell information about deadline such as "This translation must be done by October 2nd" and "this quote must be created till tomorrow". And also available to make it send an 'alarm mail' to the members in the team as one hour before the deadline.
Here we suppose a simple Workflow which has only two tasks, 'Request task' as the Upstream task, and 'Processing task' as Downstream.

In the [Process Data Item] screen, add a process data item of Date type or Datetime type. (name them [Sample] as following)
*The 'time' of a deadline is 23:59 when specified in Date type.
Set the permission of the 'Deadline' data item to "Read Write" in the [Permission] setting page, for a processor of 'Request task' can specify a deadline.
Open the property screen of 'Processing task' in Process Diagram page.
* List of Date type and Datetime type process data item will be indicated in the pulldown
