Problem with Primavera P6 version 8.3.2

change the duratrion type to fixed duration and units/time  

Helo Mohsen,

The reason for that is P6 does not work like you are assuming.

After loading the non-labor units, I assume you entered the % progress on units progress.

Based on this, the first time you enter a % progress (day 10%) for non-labor units P6 calculates correctly and places the 10% of non labor units on actual, keeping the non-labor units at completion equal to the budgeted units. The actual at completion is the value that P6 uses for computing the relative weights till summary level, as basis for progress calculation.

The error you described starts with the second value of progress (say changing the 10% to 20%). The calculation is made not anymore based on budgeted non-labor but on actual non-labor field which makes the value at completion not anymore equal to the budget you entered (thus changing the relative weight of the activity)

Several ways allow to correct the problem. One simple method is before registering the new progress enter a 0% (Zero %). After the zero enter the new value (in previous example it should be, 10 -> 0 - 20)

values passing from non-labor to labor units I never saw. Most logical explanation coming to my mind: could it be a mistake when entering the units in the wrong field ?

Hope it helps
