Time-Phasing is a required process for line items when Time-Phase is checked in the Project Setup screen (Projects > Project Setup – General tab). It does not impact line items associated with a change with a Submitted, Partially Submitted, or Approved status.
Time-phasing may be performed as follows:
Manually at either the objects or line item level.
Systematically by assigning a Start Date, End Date, and Curve (Scope, Budget, and Forecast- changes) at the objects or line item level. If a line item has a Manual curve, then the Cost, Hours, and, Quantities for those objects must be spread manually using the Time-Phasing tab. The Costs, Hours, and Quantities of objects associated with any other curve types may be systematically spread using the Time-Phase Unapproved Change action. The results of the Time-Phase Unapproved Change action can be viewed on the Time-Phasing tab. However, if the curve is not Manual, data cannot be updated.
To streamline the time-phasing of line item data while maintaining maximum control of per period values, one of the non-manual curves, time-phase the data, then assign the Manual curve to allow for per period control of values.
If the Project Exchange Rate Table is not established in Project Setup screen, the system cannot calculate Cost in Project Currency.
