Tagged: duaration task calendar. I use task calendars a lot in my schedules. The task calendar is Monday thru Friday 2 shifts at 10 hours per shift. Project is calculating the duration at 31 days but the duration should be Are the tasks with the task calendars set to ignore resource calendars? If not,the resource calendar could be restricting the amount of time a resource spends on the task. For example, if the task calendar indicates the task could be worked on M-F for 20 hours each day, but the resource calendar says the resource can only work 8 hours per day, the resource calendar will only allow the resource to be allocated to the task 8 hours a day, regardless of the task calendar.

Checking the Ignore Resource Calendar option on the task tells project to disregard the resource constraints and schedule the task solely on the task calendar. Yes I do have Ignore Resource Calendar checked. Also the duration shows 31 days when from start to finish date is only 22 days.

Daniel, Notwithstanding the excellent points Darryl has made, I suspect your issue is a bit simpler. Some other scheduling tools include these conversion factors as attributes of particular calendars rather than of particular projects; that approach has its own issues. The duration of that task is hours. This converts to a There are two general ways to avoid or reduce the confusion: a Specify durations of tasks with non-standard working hours either task or resource in hours rather than days; b Use a custom duration field with a formula to display an alternate duration depending on the applied task or resource calendar.

That formula is a one-off for the specific conditions you named. Been a little while since we talked about this. I have named my calendars 4d1s, 4d2s, 5d1s, 5d2s, 6d1s, 6d2s and 7d1s. All are 10 hour shifts. If I want my custom duration field to take into account the resource calendar, what would the nested formula need to be? If its important for such things, then you either need to add an intelligent calendar-name extension to each resource name as I showed earlier, or do the whole thing with vba.

Good luck, tom. Setting up tasks. On Standard Calendar. I have set-up for fixed duration. How can I get the duration to accurately reflect the duration? Name required :.

Let me start by saying that I’m open to the possibility that I’ve misunderstood how to set something up or that Projects wasn’t designed to do this or even that this IS a “correct” answer and I’m just not thinking about it correctly.

But beyond the gripe that there should be an option to force individual tasks to start on a new business day because frankly, that’s how things work in the real world sometimes , I cannot figure out how Projects is giving me the number it’s giving me and I’m about a half a day into trying different settings and combinations of settings to get this to resolve.

I’ve confirmed the behavior by creating a generic version of one of the summary tasks in a new file and got the same results. I have a group of tests I’m trying to schedule that all have component parts, i. Summary Tasks and Performance Tasks. A group of these tests involve long durations of continuous testing. By continuous I mean 24 hours a day, 7 days a week. There are preceding and following tasks that are part of each test for setup, tear down, report writing, etc.

By regular I mean 8 hours a day, 5 days a week. Everything is set to auto scheduling and I have a resource defined, Lot A, that has its calendar set to “24 Hour” that’s been assigned to Task B.

All in told, I count days total, start to finish. BUT the summary task which shows the correct start and end times says the duration is days??? I tried setting all of the calendars explicitly for each task including the summary task. Still get days. What’s weirder is if I set the calendar for the summary task to 24 hrs, the duration jumps to I think I kind of understand where that might be coming from. If you consider each 8 hours of the to be a day that would turn the into days, but how the other 2 days become 7.

Either way though, this doesn’t make any sense. So what am I doing wrong? Is it me or Projects that has this has this wrong? How can it show all the correct start and end times and then turn around and have the duration of the summary task wrong? Very nice detailed explanation. You’d be surprised by how many users post the most cryptic questions that often take multiple responses to understand exactly what their asking.

The “answer” to your dilemma is actually quite simple. Project has one definition for a “day” and that definition applies to the Duration field. Perhaps the best way to see how Project is calculating the Duration value is to create a custom field formula. You are using the default definition of a “day” which is 8 hours minutes and since the summary line uses the Standard calendar, the Duration is calculated as shown below.

The schedule table displays earliest and latest dates, free float and total float. Other views such as the Detailed Gantt view display the total float. How satisfied are you with this reply?

Thanks for your feedback, it helps us improve the site. Thor, Trevor gives some excellent advice. Here are some specific things to check: 1. Make sure all the summary tasks above task A have no late-finish constraints. Any of these situations could give you unexpected results. Good luck, tom. Thank you Trevor and Tom! Thanks again! In reply to thor’s post on March 24, Good luck. If this is user error i. Select “Paint House”, and bring up information shift-F2. Now, in the Work column, specify 5 days of work for the task.

With that task selected, bring up task information again shift-F2. We would now expect the Duration for “Paint House” to be 5.

However, the Duration is unchanged. This is discrepant, right? At this point, the Duration calculation appears unpredictable. Only the Duration should change when I alter the resource allocations. Is this a bug too? As you have discovered, if you want project to divide the work up based upon assignment units, you need to assign each resource separately. You are correct, project calculates resource work only upon assignment. After a resource is assigned then Project will recalculate one of variables of work.

Project will not redistribute work if you change assignment units with multiple resources being assigned. You can manually change work, and project will usually recalculate duration unless as in the circumstance you note, there are multiple resources assigned and one resource is still working on the task.

To your point about changing work on a Fixed Work task — it doesn’t unless you change a resource’s assignment units to zero. If you don’t want the resource to work on the task, remove them — and as long as the task is effort driven it is if the task is Fixed Work the total work will stay the same and will be redistributed to the remaining resources based upon their assignment units.
