Request/Demand (assignment field)

When you use “Assign Resource” dialog box for assigning resource you can see small field with mark “R/D” . This is the Request/Demand field.

Assign Resource

When you mark resource as “Demand” it indicates that the specified resource must be used and not substituted. When you mark resource as “Request” it indicates that the specified resource should be used unless the resource is over allocated. Request/Demand field is manually entered and can be used to specify how and which resources can be assigned to tasks when the Resource Substitution Wizard is activated.

The default option is “Blank”, indicates that any qualified resource can be assigned to the task.

This option can be best used with Task Usage or Resource Usage view when you want to display or change the resource substitution type for an assignment.

Note that the Request/Demand field is disabled for generic resources.

In Project Professional 2010, connected to Project Server 2010, it was possible for project managers to assign resources to tasks and then specify whether that assignment was a Request or a Demand, depending on their view of which resources could carry out that task. Running the Resource Substitution Wizard would then attempt to level resources.

The Resource Substitution Wizard is no longer available in Project Professional 2013, so one would assume that there would be no need to be able to specify a Request or Demand field for resource assignments.
