Modules and Views → Configuration → Attributes Setup → Attributes → Timephased
A timephased attribute (or field) is used to store information whose value can change over time. There are several types of timephased attributes: Timephased - CURRENCY, Timephased - FTE, Timephased - HOURS, Timephased - NonLabor, and Timephased - UNITS.
Add a new timephased attribute. From the Type drop-down, select Timephased - CURRENCY, Timephased - FTE, Timephased - NonLabor, or Timephased - UNITS. If you select Timephased - FTE or Timephased - UNITS, you can assign rates to the attribute. If you select Timephased - FTE, you can use it with a labor attribute map.
Labor attribute mapping is done using attributes that are based on the Timephased - FTE attribute type and have the Mappable option selected.
