Kumar,

that's the same thing: Duration = (Finish-Start)/Default hours per day

therefore:

  • Task A starting oct/1st, finishing oct/5th with a 8h/d calendar will represent 5 days and 40 hours
  • Task B starting oct/1st, finishing oct/5th with a 24h/d calendar will represent 5 days and 120 hours, but MS Project will display "15 days" (120/8)

Hello Alexandre,

Thanks for your reply.it was useful Info.

But i was not looking for the irregularities in the bar length.I was facing the problem with the Duration column.

for ex If A activity is starting on 01-Jan-2012 and Finishes on 05-Jan-2012.So this means in the duration column it should show as 6 days.But in my project the duration is showing as 10 days.this is because in my project the default working duration is 8 hrs but for the turaround i have to work 24 hrs per day.

so here i am facing the problem.....is there any solution for this..

 

thanks

Hello Kumar,

I remember that Paul E.Harris had suggested a way of doing a few years ago, but I cannot find it

Herebelow my answer for the 1st part of your question, I hope somebody will answer the second part:

You will use 2 custom fields to display the correct duration of tasks and length of bars:

1. Use the task custom field "Duration1" and create the following formula:

IIf([Task Calendar]="24 Hours";[Duration]*3;[Duration])

2. Use the task custom field "Finish1" and create the following formula:

IIf([Task Calendar]="24 Hours";ProjDateAdd([Start];[Duration1];"24 Hours");[Finish])

3. In the Format Bar Styles dialog, change the "To" field value for the Critical and Non Critical tasks from "Finish" to "Finish1"

The task bars will have a correct display, should the calendar be 8h/d or 24h/d

Now, I hope somebody will tell you how to manage the links correctly
