7. Choose Tools, Global Change and run the 1st Global Change. (See below) This will set the Actual Material Units to zero.
8. Run the 2nd global change (See below) which sets the activity status to Not Started.
1st Global Change:
Subject Area:
Activity Resource Assignments
Then:
Actual Material Units = 0

2nd Global Change:
Subject Area:

Where Activity Status is not equal to Not Started
Then:
Activity Status equals Not Started
If this process is not used you may encounter the following error:
"Cannot set status to Not Started if activity has actuals."
