Predessor and sucessor Finishes and Start Same date

I have also faced a similar problem some time back and my mistake was with calender settings. Predecessor activity ends at 15.00 hrs that day and calender defined is up to 18.00 hrs on the same day. So, the successor activity will start at 16.00 hrs on the same day n there by resulting the same date. But, in version 7 they have enhanced this by giving an option to display it in minutes.

Go to user preferences--->Dates n display time (If possible minutes). It enables you to find the exact time at which the predecessor activity is ending and the successor activity is starting.

Then you may opt one option among the following 

1.Go to calenders and adjust the "time period" accordingly. Your "time period" definition should match with your detailed work hours/day. For example you might have assigned 10 hr/day and in your detailed work hours/day, it might be anything other than 10 hrs..

2.And also check the same calender is been assigned to the activities, WBS n to the project.

3. If you get this problem when updating the actual dates then check the staus bar of activity details; exact date and time.

Dear haresh ,

The problem is mainly with calender only for solving this problem simple way . assign allactivities to standard calander and in standard calander just click standard will change to default calander and use the same calander to all activities then you will get answer.

or if you want why it is happining  change the date format using user preferences and change the date format with time you will understand why it is happining

Dear All,

I have done all the changes in settings, but no positive results. I have changed the working hours both in User preferences, Project start date, calendar, schedule time, all but I am facing this problem wherein the successor is starting at the same day of predecessor.

I went to user preferences, and activated the option to show minutes. When I analysis the situation if predecessor activity is completion on 24^th August 2010 12:00pm , then the successor activity is again starting at 24^th August 2010 , 2:00pm. Kindly given remedial solution to this problem.

As a default, in P6, Project planned start date would be at 00.00 hrs that day. Change that time to your calender start time. Also check the time at which the first activity in that particular WBS is getting started. I think, that is the reason why the predecessor activity is ending at 12.00. And you might have defined 12.00-2.00PM as a non work period. So, successor is starting at 2.00PM on the same day.
