How to remove the gap between actual bar and remaining bar in schedule update in Primavera P6

In the schedule update of Primavera P6, there is occasionally a gap (empty space) between the actual bar and the remaining bar as illustrated in picture below.

he reasons and solutions for the issue are described in this article.

Reason 1:

Primavera P6 schedules and displays the activities on Gantt chart very accurately, and up to the level of minute.

By default, the Data Date (blue line) is displayed at 00:00. The activities usually start at 08:00. That’s why there are gaps between the Data Date and the remaining bars.

Solution 1:

• Go to menu Edit -> User Preferences. Select the option to show the time:

When running schedule (F9), set the time of Data Date to 08:00:

Finally, the gap has gone:

Solution 2:

• Right click on Gantt Chart -> Select Bars
• Change the value of Timescale of “Remaining Work” and “Critical Remaining Work” to “Current Bar”:

Select the “Actual Bar” and click the Shift Down button until its position is below the “Remaining Work” and “Critical Remaining Work” bar:

Finally, the gap has gone:

Explanation:

• The “Current Bar” in Timescale represents the Start Date to Finish Date;
• So, the “Remaining Work” and “Critical Remaining Work” bar are actually displayed from 29-Jan-20 to 02-Feb-20;
• However, the “Actual” bar are displayed on top of “Remaining Work” and “Critical Remaining Work” bar. Therefore, the “Remaining Work” bar seems to start from the Data Date.

Reason 2:

The activity started out-of-sequence and Schedule Option is set to Retained Logic as illustrated in picture below.

Solution:

The gap could be removed by switching to Progress Override mode in Schedule Option. Then, the start date of remaining work of activity B will move to the Data Date.

Finally, the gap has gone:

Important Note:

The decision to change from Retained Logic to Progress Override mode has to be reviewed and approved by all relevant parties of the project.
