to get earned value you have to use Physical % comple. However using physcial % complete does not update the remaing duration like duration % complete does.

for example a 6 day activity started and is 50% complete using physcial % complete remaining duration is still 6 days

however a 6 day activity started and is 50% complete using duration % complete the remaining duration is now 3 days

a trick to make this easy is to use duration & complete then run a global change where physical % complete is equal duration % complete.

Roozbeh,

I supposed what Rodel is saying is that you cannot roll-up physical percent complete unless you convert it to performance percent complete, wherein you will need costs.

For me, one of the advantages of using "physical percent complete" is that you can play with the "steps".

cheers

Roozbeh,
If you don’t have cost whether Duration or unit % complete type is use it will not roll up to summary and equivalent to zero only for Performance Percent Complete. Check it to confirm. The duration Percent complete that you are saying is based on Duration Progress and not Activity Progress Summary (weighting).

For Example:

Roozbeh,
All activity types are represented by Activity % complete without rollup and Performance % complete with rollup summary.

All of them will not have summary or equal to zero summary if the program is not cost loaded.

Physical is used using Physical actual effort, duration is normally used for duration base (fixed durations or duration driven) and units are resource effort (fixed unit or unit/time). All of them can be rollup in a summary using Performance % complete especially if mixed activity type is used. If all activities are perform using durations then Duration % Complete type is applicable to rollup summary in summary band which is the same approach for units if resources are measured against fixed unit or fixed unit/time. If measuring Physical effort or Actual effort of progress then Physical is more appropriate to use which allow you to progress activity different to duration or units. Using Physical % complete doesn’t synchronize the update of duration and units which requires manually update or adjustment for both.

Ex: Act 1 = 5 days with 40 units.
If Act 1 Physical effort progress = 80% but the remaining duration might still have 2 days to go which is not the same as duration % complete and possible have 4 units to go which is also not the same as unit % complete.
If duration % complete is used = 80% progress will automatically returned 1 day remaining and if using units = 80% progress will automatically returned 8 units remaining.
Both duration and units might not reflect physical effort or actual progress which is totally reflect wrong earned value except if both are measured correctly and reflect actual progress.
