The benefit rate for personnel is determined by the UW sub-object code you select in Personnel Details. If an individual working on your proposal will change roles mid-way during the lifespan of your project, you need to add that person to your budget twice: once for each role they will occupy. Select the appropriate UW Sub-Object Code, or role, for the person, and then enter the % effort for each budget period. For periods in which they do not occupy the specified role, enter 0% effort. The correct benefit rate will automatically be applied according to the role and percent effort you specify.
