Hi Friends,

Here I got it in Prief alltogether in one place:

Percent Complete Type The activity percent complete type is one of "Duration", "Units", or "Physical". The percent complete type controls whether the Activity % Complete is tied to the Duration % Complete, the Units % Complete, or the Physical % Complete for the activity. Set the percent complete type to "Duration" for activities which are duration driven, for example, administration tasks and training classes. Set the percent complete type to "Physical" for activities which are work-product driven, for example, creating a document or a product. Set the percent complete type to "Units" for activities which are work effort driven, for example, providing a consulting service.
Activity Percent Complete Fields

Physical % Complete The activity physical percent complete. The physical percent complete reflects the actual progress made on the activity’s work products so far. Physical percent complete can be manually entered by people familiar with the status of the activity’s work products or it can be based on the completion of assigned Steps. Always in the range 0 to 100.

Duration % Complete The percent complete of the activity duration. Computed as ((Planned Duration - Remain Duration) / Planned Duration) * 100. Always in the range 0 to 100. The planned duration is taken from the current plan, not from the current baseline.
Duration % of Planned The activity actual duration percent of planned. Computed as (Actual Duration / BL Duration) * 100. The value can exceed 100. The BL Duration is the activity’s at complete duration from the current baseline.

Activity % Complete The activity percent complete. This value is tied to the activity Duration % Complete, Units % Complete, or Physical % Complete, depending on the setting for the activity’s Percent Complete Type, which is one of "Duration", "Units", or "Physical". Always in the range 0 to 100.

Schedule % Complete The Schedule % Complete specifies how much of the activity’s baseline duration has been completed so far. Computed based on where the current data date falls between the activity’s baseline start and finish dates. If the data date is earlier than the BL Start, the Schedule % Complete is 0. If the data date is later than the BL Finish, the Schedule % Complete is 100. The Schedule % Complete indicates how much of the activity duration should be currently completed, relative to the selected baseline.

Note: Summary Schedule percent complete when displayed on an organize band, will ALWAYS be calculated as (BCWS* 100) / BAC, regardless of what earned value technique is selected for the activity’s WBS.

Performance % Complete Performance percent complete is used to compute earned value and may be based on the Activity % Complete, on the 0/100 rule, on the 50/50 rule, etc., depending on the technique for computing earned-value percent complete for the activity’s WBS. The Performance % Complete specifies what percentage of the activity’s planned worth has been earned so far.

Note: Summary Performance percent complete when displayed on an organize band, will ALWAYS be calculated as (BCWP * 100) / BAC, regardless of what earned value technique is selected for the activity’s WBS.
