Hi Suresh

We can not get activity % complete from UDF through Global change fuction.

I suggest that you should update progress directly to physical % complete field, instead of UDF.

But’Physical % complete’ is not rolled up, because it is a
discrete, user entered value assigned to an activity. Since
’Physical % Complete’ does not relate to the duration,
units or costs of the activity, there is no common
denominator to use for the summary.

However there is a workaround to roll-up physical % complete to WBS level.
Workaround:
It is possible to configure the Activity’s ’Performance %
complete’ to equal the ’Physical % complete’.
Performance % complete can be rolled up to the summary
bands. However, to achieve this, the following three
statements need to be true:
1) The ’% Complete type’ of the activities must be
set to ’Physical % complete’. This option is located
in the General tab in the Activities View (Note: this
will set the ’Activity % complete’ value to be equal
to ’Physical % complete’. This will also impact the
Earned Value calculation.)
2) The ’Technique for calculating performance %
Complete’ needs to be set to Activity % complete.
This option is located in the Earned Value tab in the
WBS View (Note: this will set the ’Performance %
complete’ value to be equal to Activity % complete,
which equals Physical % complete).
3) Finally, in order for the Performance %
Complete to be rolled up to the summary band(s),
costs need to be assigned to the activity. These
costs must also be present in the Primary baseline.
Please Note:
At the summary level, the Performance %
complete is calculated as follows:
Performance % Complete = (BCWP * 100) / BAC
(Where the BCWP is the Budgeted Cost of
Work Performed and the BAC is the Budget At
Completion)
BCWP is calculated as Activity % Complete *
Baseline Total Cost
By setting the 3 conditions above, the Activity %
complete will equal the Physical % complete thus
ensuring that the summary value for Performance %
complete is calculated with regard to the Physical %
complete, weighted by the activities’ cost.

Thanks & regard

Dear Suresh!
Actvity have 3 percent complete type : duration, units, physical.
Depend on which type you choose for activity, the value will reflect in "Activity % complete" column.
The main factor you should focus when analyse updated schedule is "Activity % complete" column, not physical % or duration %.
Duration, unit, physical % column is just used for temporary store.
Calculation of Earned value will base on activity % complete.
So, there will be no confict if your duration and physical % are diferent. Because Primavera just look at Activity % complete for calculation.

Please feel free to contact me if you have problem

Thanks
