(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

As well as viewing the Original Duration column, also include the following:

  • Original Duration (OD)
  • Actual Duration (AD)
  • Remaining Duration (RD)
  • At Completion Duration (ACD)

This will help to explain how the various duration values are used. As a rule

  1. AD+RD will always equal ACD
  2. OD = RD when the activity has not started
  3. AD = ACD when the activity has finished

Note that none of the above refer to durations from any baseline projects. For that you need to Look at BL/BL1/BL2  Duration values as well.

if you dont want it to do that then remove it.

What the expected finsh date will do will automatically calculate the duration from the date that the activity is schedule to start to the expected finish date that you entered.

If your activity has not started, That is what it is supposed to do.
