PRJ: Can't Enter Duration in Replace Resource Dialog Box
This article was previously published under Q113312
SYMPTOMS
In Microsoft Project, when you replace a resource using the
Replace
Resource dialog box, and you enter a duration value in the
Units column for the resource, such as 8h, you receive the following error message:
Units must be between 0 and 100 and in hundredths or greater amounts.
-or-
There is a problem with the value.
This is not a valid units value or is outside the range for this field.
Units must be a postive number between 0 and 10,000 (or 1,000,000
percent) with up to two decimal places.
: To locate the
Replace Resources dialog box, point to
Resources on the
Tools menu, and click
Assign Resources. In the
Assign Resources dialog box, click the
Replace button.
CAUSE
By design, when you assign a resource to a task, the units of the resource
assigned are converted to a number of units, even if the value you enter is
a duration such as 4h. However, when you replace a resource, the units
value is assumed to be in terms of units because the resource has already
been assigned to a task.
Note that when you replace a resource, the replacement resource is assigned
to the default units value (1.00). If you want to replace the resource with
the Units value that the original resource was assigned, you must enter
that value in the Units column for the replacement resource in the Replace
Resource dialog box.
WORKAROUND
To work around this behavior, use the
Remove button in the
Resource Assignment dialog box to first remove the resource, then use the
Assign button to assign a replacement resource with a duration value in the
Units field.
MORE INFORMATION
NOTE: If you attempt to enter a work value for an existing resource
assignment in the
Resource Assignment dialog, Microsoft Project behaves as follows:
For a resource driven task, the units will be increased or decreased by
the same proportion by which you are trying to increase or decrease the
work, but the work will remain the same. For example, if a resource is
assigned at 2 units and 80h of work, and you enter a work value of 120h,
the resource will be assigned at 2 units x (180h/120h) = 3 units, but
work will remain at 80h.
If the task is fixed duration, the behavior is the same except that work
also changes to the value you entered in the units column. In the
example given, you would end up with the resource assigned at 3 units
and 120h.

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
Thank you for using kbAlertz.com Feedback System.
