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

Reason 1:

Primavera P6 schedules and displays the activities on Gantt chart in a very detailed and precise manner – 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:

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.
