Actual Duration in P6

Suresh
To your first question: Main difference is the data date in Primavera (all versions): This is "today", but activity’s calendar will be regarded. So duration %-complete is calculated from Start to data-date. MSP doesn’t know a common status date: one activity might have status April 1st, another Mai 5, another ... If you import this can lead to differences - or, you had some discipline using MSP.
Second question: For costs and units you decide per project how it’s calculated Tab calculations. For the durations it depends on duration type and the percent-complete type and the data-date of course.

Dieter,
Its not cleared actually.

The question is in MSP the Acutal Duration calculates
Actual Duration = Original Duration * % Complete

But how will P6 calculate the actual duration ?

Suresh
Primavera calculates different. This is from the P6 "Hint Help":
Duration % Complete: The percent complete of the activity duration. Computed as (Original Duration - Remaining Duration)/Original Duration * 100. Always in the range 0 to 100. The Original Duration is taken from the current plan, not from the baseline.
The actual duration is the difference between "Actual Start" and the Data-Date. The data-date is the current status of a project: earlier is past, later or equal is planned for the whole project. MSP here is a little chaotic.
