% of work load

[SuzMills]

I have a resource that is only available for 35% of her time, my task is a 20
hour task, I have flagged her units for the task at 35%, her work day is 8
hours giving approx 2.8 hours per day to do the 20 task that means the
duration should be around 7 days, however my plan shows the task duration of
Aug 15 - Aug 17. I have no date constraints - what am I doing wrong

Assign her to the task itself at 35%.

Remove the resource from the task, set the task to be "fixed work" in
any task form, then reassign the resource at 35%.
Hope this helps in your world.

so can you help me pleassssssssseeee?

When you "flagged" her units at 35%, was the task type set at "fix Duration"?
If so, the work probably reduced without you knowing it. You would need to
make sure it was fixed work when you changed the unit to 35%.

I figured it out - I had duration opposed to work populated with the 20
hours...so I'm good thanks very much

When you make the first resource assignment to a task, Project assumes you
had the % you assign in mind when you made the original duration estimate.
So I'f I have a task that is 20 hours duration and I assign Joe to it 100%,
it stays at 20 hours. But if I assign Joe at 50% it ALSO stays at 20 hours.
If I assign him at 10% or 72% or anything, the same 20 hour duration will
remain as long as it's the FIRST assignment.
