wrong FINISH DATE

Posted Thu, 2019-09-19 05:37 by Warren Sika

I am preparing a recovery program using P6 and I am facing the issue of having a wrong FINISH DATE.

The activity (selected) has remaining duration of 2 days and its predecessor's Finish Date is 25 Sept. With this scenario, I believe the activity has to have a FINISH DATE of 2 days after the 25 Sept - means Sept. 27. But the calculated P6 Finish Date is 23 Oct which is 28 days difference. I have FS relationship. Not only this activity but so many in my program as well.

You can see in the gantt chart how it behaves.

I tried different Duration type but same outcome.
Why? Can anyone help me? Is there any way to do this?

Im using a Retained Logic. I think progress override is not a good option as it breaks the sequence of the work.

All calendars are set to 6 days.

Anyone who wants to check the entire program, I can send. Comment your email.
