Problem: Gantt View Data do not Agree with Resource Usage View data

[n]

When viewing through resource usage the data associated with one of two
resources assigned to a single task, the start and stop dates do not
agree with the Gantt view. The work appears to have been compressed
into the first three months of what should be a 7.5 month long
duration. ?



For the Same task:

View Start Stop Duration Work Units


Gantt 29Jan07 14Sep07 7.5 mons 704 hrs N/A

Resource Usage 29Jan07 14Sep07 N/A 528 hrs 60%
(Resource #1)


Resource Usage 29 Jan 07 29 Mar 07 N/A 176 hrs 40%
(Resource #2)



Other task parameters:

Fixed Units
Effort Driven: NO
Constraint: ASAP
Start Determined by Start to to Finish Predecessor relationship

Have you manually entered actuals on this task in the Microsoft Project
plan? And if so, did you republish the assignments using the following
steps:

1. Click Collaborate - Publish - Republish Assignments
2. Select the "Overwrite actual work entered by resources" option
3. Click the OK button

Let us know.

The Gantt view represents the duration of the entire task. The second
assignment that's troubling you simply doesn't span the duration of the
entire task. If you wanted it to, you would have needed to assign the
resource at a lower percentage of units. Doing the math, based on 40% of an
8 hour day, Resource #2 completes the assigned work in 55 working days,
whereas Resource #1, at 60% of an 8 hour day finishes in 110 working days.
Exactly twice as long as the second resource assignment.

I don't know what your working day is set to and I don't know what calendar
settings and exceptions are governing these assignments, but they seem more
or less accurate and plausible as stated, although I'd expect resource #2 to
finish a calendar week or two later than stated with typical calendar
exceptions and resource #1 to complete the work a little sooner unless
vacations and company holidays are pushing out the date.

The bottom line here, is that the math mostly makes sense even in absence of
a complete set of facts. You need to apply the task usage view and zoom to
weeks over days to understand the work distributions which determine the
durations of each assignment. There are likely gaps in the work contours of
both resources, or leveling delays, or something like that causing the
extended durations.
