Planned Dates change with Early Dates

Hi Mangesh



Herein I give you some definition of activity date. Hope it can clarify you queries after researching them carefully.



Start

For an activity that has not started, the current start date of the activity. Set to the remaining start date until the activity is started, then set to the actual start date.



Finish

For an activity that has not started, the current finish date of the activity. Set to the activity planned finish date when the activity is not started, the remaining finish date when the activity is in progress, and the actual finish date once the activity is completed.



Early Start

The earliest possible date the remaining work for the activity can begin. This date is calculated by the project scheduler based on activity relationships, schedule constraints, and resource availability. The Early Start equals the Remaining Start unless you preserve the scheduled early dates during leveling.



Early Finish

The earliest possible date the activity can finish. This date is calculated by the project scheduler based on activity relationships, schedule constraints, and resource availability. The Early Finish equals the Remaining Finish unless you preserve the scheduled early dates during leveling.



Late Start

The latest possible date the remaining work for the activity must begin without delaying the project finish date. This date is calculated by the project scheduler based on activity relationships, schedule constraints, and resource availability. The Late Start equals the Remaining Late Start unless you preserve the scheduled late dates during leveling.

Planned Start

For an activity that has not started, the date the activity is scheduled to begin. This date is set equal to the early start date by the project scheduler but can be updated manually by the project manager. This date is not changed by the project scheduler once you apply an Actual Start date.



Planned Finish

For an activity that has not started, the date the activity is scheduled to finish. This date is set equal to the early finish date by the project scheduler but can be updated manually by the user. This date is not changed by the project scheduler once you apply an Actual Finish date.
