Glad I could help 

1st go to projects directory and make sure that you project is highlighted 

now goto the calculations tab and make sure that on the right under resource assignements that when updating Actual unit or costs tats Subtract Actual from at completion is checked

now make sure that recalculate actual units and cost whne duration % complete changes

no make sure that link actual and actual this period units and cost is checked.

this will update your actuals based on the duration % complete but since you are physical % complete you wil hev to run a gloabl change after each update 

to do this do to tools Global change then on the right select new

give the title make it Change Duration % complete to equal physical % complete

the parameter should look like this 

Where  Physcial % complete is greater than 0

then duration % complete = physical % complete

then on the right select Change 

then select Yes

then on the lower right select Comitt Changes

then close it and close the global change

now your actuals have been updated

now you can run your reports 

prior to next update select Tools then Store Period Performance 

now update your schedule using physcial % complete as you usually do

when done your the global change again.
