MS Project cannot resolve overallocation for a resource

[MarkS]

Hi,

Using a combo Gantt / Resource view, I am going through the project's tasks
to "optimise" the project. In my schedule I am have set levelling to manual.
When I try level on a selected resource, I get the response that "Microsoft
Project cannot resolve the overallocation of (Resource) on (Date). I have
set no contraints on the tasks - all default to start as soon as possible. I
have however got the resource starting (set using available from) a date post
the task that is causing the conflict. I would have thought MS Project would
have pushed the task to commence only after the date the resource is
available? I am not keen on manually pushing the task date as that imposes a
task constraint. Any suggestions?

thanks,
Mark

Hi,

When I try this Leveling does push the task into availability territory.
I have seen this message mostly when the work requested on a single task
during a leveling period exceeds the availability as expressed through the
max units.
Could you verify that?

Hi,
Many thanks for your assistance. I created a two-task test project and
encountered the same problem (I guess I should have tried this test first).
The problem was that the "level only within available slack" box was checked
(something I must have done unintentionally as it states the default status
is cleared).
Thanks,
Mark
