Hi Norman,
Request/Demand is an assignment field in Project. The following information
is from MS Project help in 2003.
===========================================================
Request/Demand (assignment field)
Data Type Enumerated
Entry Type Entered
Description The Request/Demand field provides choices for how resources
are to be assigned when using the Resource Substitution Wizard. You can
request that a specific resource be used if not overallocated, require that
only a specific resource be used, or use any qualified resource that results
in the shortest schedule.
Best Uses Add the Request/Demand field to the sheet portion of the Task
Usage or Resource Usage view when you want to display or change the resource
substitution type for an assignment. The Request setting indicates that the
specified resource should be used unless the resource is overallocated. The
Demand setting indicates that the specified resource must be used and not
substituted. The blank setting, which is the default, indicates that any
qualified resource can be assigned to the task. This resource is the one that
results in the shortest schedule across all projects.
Example You assign a resource to a task. You know that this resource is
the only one capable of performing the task. To keep this resource assignment
when you run the Resource Substitution Wizard, you select Demand in the
Request/Demand field for the assignment.
Remarks This field is also available in the Assign Resources dialog box,
the Resources tab in the Task Information dialog box, and the General tab in
the Assignment Information dialog box.
The Request/Demand field is disabled for generic resources.
============================================================
Hope this helps. Let us know how you get along.
