Actual Units for Assigned Resources are not correct as per physical %

Hi,

I need some help from your rich experience in updating resource loaded program.

Actually i am facing some issues while updating the resource loaded items. When I update the physical %ge complete of the task, I think the assigned units will also updates by its own and same with remaining units. But in my cast, it is not happening and I need to update them manually which is very time consuming. Some time the material resource gets updated but the labour resources are never line up.

Below is the example for that:

One item has assigned resources as follow:

Labour      -   500 hr

Material    -  1000 units

Nonlabour -   250 Hrs

Now when I update the item with physical %ge as 50% complete, my atual resources for labour is 0 hr, Actual material - 500 units and actual nonlabour - 125 hrs. Activity type is task dependent and duration type is Fixed Duration & units. We are using enterprise version and my admin don't know either if it is because of some incorrect settings or what?

I will really appreciate your help on this.

Many Thanks
