Not Enough Common Working Time

Question

I'm using MS Project 2010. I have a number of work plans created, linked to a master work plan and am using a single master resource pool. When the master resource pool file is opened, the message below is shown. Has anyone encountered this and knows what is causing it/what the solution is?

Answer 1

Hi,

The task must also have a Task Calendar.

The working time in this task calendar all coincides with nonworking time in the resource's calendar from the pool. For instance, if the task calendar forces the task to be done during the weekend, and the reource calendar is standard, there is no way to plan the task satisfying both demands.

The solutons are in the message!

Greetings,

I ran into this same issue and finally figured out the cause (for my case, at least).

Somehow, a task had been assigned a "Start No Earlier Than" date, and I had scheduled it for earlier than that.  Once I figured out this was causing the issue, I removed the constraint and the error went away.

Hope that helps!

Hello,

This calls for another question. How did you "schedule it for earlier" ? What data put you in? Normally I would expect to see the SNET constraint changed?

Hi,

You must have A (at least one) task with a task calendar in your work plan. You can find it when you insert the column Task Calendar - it will by default say None but if you have assigned a Task Calendar to one of the tasks you will see it there.

Now at least one of the tasks with a task calendar will also have one or more resources attached.

With the pool closed, these resources will have their calendar taken from the work plan itself, and visibly this calendar has no exclusion with the task calendar (if it would you would have the message already there and then). ut when you open the pool, the resource will  now inherit its calendar from the pool- and that one does have this sort of exclusion with the task calendar. Hence the message.

Hope this clarifies,

Jan,

Thank you for the quick reply. In my master resource pool file I do not have any tasks so I'm still not sure what you mean? I would appreciate more detail to help me resolve this.
