MS Project 2010 Tips – Splitting In-Progress Tasks

99 Tricks and Traps for Microsoft projectSetting an In-Progress Task

When the Split in-progress tasks option is enabled in the Tools, Options…, Schedule form, a task will Split automatically when a task commences before its predecessor finishes.

Microsoft Project is inconsistent when the Split in-progress tasks option is used with tasks that are assigned with one of the following options:

  • An Actual Start and 0% Complete — these tasks are not split, or
  • An Actual Start and % Complete set between 1% and 99% Complete — these tasks are split.

The two examples below are from the same schedule, both with the Split in-progress tasks option checked, one with 0% and one with 1%. You will notice the task assigned 0% has an earlier Finish  date than the task assigned 1% Complete, which has split.

Note: You therefore need to pay careful attention to any warning messages Microsoft Project presents.

Microsoft Project 2010 Tips and Traps – Resource Calendars

99 Tricks and Traps for Microsoft projectResource Calendars

Each resource is created with its very own editable calendar. Here are some important points:

  • Each new resource is assigned a copy of the current Project Calendar as its Base Calendar.
  • This Resource Base Calendar may be changed in the Resource Sheet or Change Working Time form to another Base Calendar.
  • Any change to a Base Calendar will be reflected in any Resource Calendar.
  • The Resource Calendar may be edited to suit the availability of the resource. Days may be made non workdays to represent holidays, etc.
  • Normally the duration of a resourced task calculated from the Resource Calendar.
  • A task will finish at the end of the longest resource assignment when there are two or more resources assigned to a task that have different end dates due to different Resource calendars or assignment durations.
  • When a Task has been assigned a calendar and the check box in the Task Information form Advanced tab Scheduling ignores resource calendars is checked the task duration is then calculated from the Task calendar.
  • The Finish date may be calculated differently after a task is assigned one or more resources when the Resources Calendars are not the same as the Task Calendar.
