You can assign a resource distribution curve to any resource or role assignment on activities with a duration type of Fixed Duration and Units/Time or Fixed Duration & Units. Resource usage and costs are distributed evenly during an activity unless you specify nonlinear distribution using curves.
To assign a resource curve:
- Click Projects.
 - On the Projects navigation bar, click Activities.
- On the Activities page, to set the Duration Type to Fixed Duration and Units/Time or Fixed Duration & Units, click Customize View and click the Columns tab.
 - On the Columns tab:
- Expand General in the Available Columns section.
 - Double-click Duration Type.
 - Click Save and Apply.
 
 - On the Activities page:
- Select Fixed Duration and Units/Time or Fixed Duration & Units from the Duration Type list for the activity whose curve you want to configure.
 - Click the Assignments detail window.
Note: You must assign a resource or role to the activity.
 
 - In the Assignments detail window, double-click the Curve field, and click Select.
 - In the Select a Resource Curve dialog box, select a curve and click OK.
 
 
Tips
- If you assign a resource curve to an assignment with a manual curve, the manually-entered future period values will be overwritten.
 - Resource curves do not support expenses. The Accrual Type will continue to spread the expenses.
 - If the Curve column is not available, add it to the detail window.
 - You can also assign resource curves to resource or role assignments from the Resources Assignments page.
