Task Re-Assignment Changes Work Hours RRS feed

  • Question

  • We are using Project Professional 2010 and Project Server 2010. The PM assigns a Fixed Work task to a generic resource. The task has more than one resource assigned to it.  The resources are spread out from many departments. When the department Resource Manager for one of the Generic Resources re-assigns their generic resource to a named resource the amount of work for ALL resources changes. This happens whether the task is started already or not. And, the amount of the work change seems to be inconsistent - sometimes it goes from 5 hours to 0.3 and other times to 89 from 5.  It is also inconsistent about which resources it changes - it is not an even spread across the recourses.  We are not using the "Department" feature.  The resources have the same calendars, same max units and the generic/named resources seem identical in all settings.

  • Hi

    How do you exchange the resource? Using the "replace" in "Assign Resource" dialog?

    Regards

  • The Resource Manager goes into PWA, edit mode and does the Replace in the Team box. And, it does re-assign but the hours just go whacky (whether there is work or not already on the task).

  • Hi Collin

    this is strange because work of fixed work tasks should nog change. Are you sure you do not have fixed duration?

    we had some issues with changing work/duration as well. When you change a resource for a fixed work tasks, project 2010 changes the duration if it is > work. I find this choice quite strange. You may want fixed duration when dealing with fixed work tasks, right? This is impossible to set. Why cannot we fix two variables and make one free (units)? So unless you have units=100 , you are in trouble when replacing recources.

    Anyway, In our case we have duration often longer than work, so the units are not Always 100%. a VBA code is used to replace resources and the same code recalculates the units based on the given amount of work and duration for a task.  Keep in mind that units are rounded to 2 decimals, so you can get a slight change in the duration after you set the recalculated units.

    Good luck!

  • Hi Collin,

    he replaces the resource in the "build Team" Dialog? Not on the task itself?

    In PWA there is no "replace" of a resource on task Level. You remove the resource and by that delete the assignment. Then you assign a new resource. This leads to recalculation of the units

  • Hi Maxim,

    Colins issue is inside PWA and not in Project Professional.

    The golden rule in Project is that "unit" is the top Parameter, followed by work. So if you have a fixed work task and Change the work, the Units will stay the same as before. If you have a fixed Units task and Change the Units, the work will not Change.

    If you have  a task with duration and work set, Project will calculate the Units to fit into it. And if you use the replace resource dialog in Project Professional, the units should stay as the have been before. And yes, this is also the case if you have 80% units on the assignment and the new resource is only available for 50%. This is something that you need to take care for yourself - the red man indicator on the task helps you with that.

  • Hi again,

    I apologize for not being more clear.  The method of reassignment is done by the Resource manager going in PWA into the Tasks screen and then re-assigning the task via the Task Reassignment page.  In the Task Reassignment page they get a list of names and can replace the assignment with the new person's name . 

    These tasks are definitely Fixed Work but more often than not the duration has been adjusted - but they are still designated Fixed Work.

    Also - the Resources are staying at normal 100% of units - there is no indication of them being over or under in the Resource assignments - they just stay at the name (but, yes, the little red man of overcapacity shows up when it should).
