Primavera P6 calculating Finish Date at 8 AM if it has FF relationship with Negative Lag
In my projects, the finish date of an activity ends at 8 AM instead of 5 PM. This occurs to activities where LAG has negative days. Here below I have created an example project with the same scenario. As you see in the below image, the finish date of third activity ends at 8 AM even it has a full Planned Duration in it.
The following project has three activities;
- The Activity ‘1’ successor is ‘2’ and ‘2’ successor is ‘3’
- The Activity ‘2’ is a Finish Milestone, ‘1’ and ‘3’ are Task Dependent Activities
- Lag of -1 day is assigned to predecessor of ‘3’ rd activity
- Standard 5 Day calendars assigned to all activities; There is no exception in the calendar;
Finish Date ends in AM If I Scheduled the project on 24-Jun-17
Adding negative day lag will remove the corresponding working hours per day from the date and shows Finish Date in 8AM.
