Project and Financial Plan Period Amounts: How They Are Calculated Using Daily Spread Basis
Calculating Distribution Factors for Spread Curves: Examples
Spread curves let you distribute quantity, cost, and revenue amounts automatically across accounting or project accounting periods. You assign a spread curve to each resource class. Planning resources (in the planning resource breakdown structure) inherit the spread curve setting from the associated resource class. You can change the spread curve for the planning resource and for any corresponding task assignments, or budget or forecast lines.
You can create spread curves, use predefined spread curves, or edit them as required. The following is a description of spread curve components (spread points and distribution factors) and predefined spread curves.
Spread curves, other than Daily Spread Basis contain 10 spread points. Specify distribution factors for any combination of the spread points.
Note
When using a daily spread basis, amounts are allocated to each period based on the ratio of the days in the period to the duration of the task assignment.
During financial or project planning, spread points are distributed proportionately across periods. For example, if amounts are to be spread across four periods, Oracle Fusion Projects allocates the combined value of 2.5 spread points to each period. The spread points for each period are the total number of spread points divided by the total number of periods (10 / 4).
Distribution factors are prorated according to the spread points allocated to each period. For example, if $100 is to be spread across four months for a planning resource that uses an even spread curve (where amounts are distributed evenly), then each period is assigned $25. The amount assigned to each period is the total amount multiplied by the spread points for the period (2.5 * 10).
Important
Spread points without values are assigned a zero distribution factor and hence corresponding periods are not allocated any amounts.
The following table lists predefined spread curves provided by Oracle Fusion Projects.

Daily Spread Basis |
Ensures the spread is based upon the number of days in each financial period throughout the duration of the task assignment. Amounts are proportionally distributed throughout all periods for the duration of the task assignment. |
None |
Assign the Daily Spread Basis spread curve to a resource class or planning resource to proportionately distribute budget, forecast, or project plan amounts across periods based on the ratio of the days in each period to the duration of the task assignment.
You cannot define spread points for the Daily Spread Basis spread curve. Therefore, distribution factors are not calculated. Task assignment start and finish dates determine the number of days in each period, including the first and last periods, and consequently the allocation factor for each period.
Note
Assignment start and finish dates are included in the number of days in the period.
When calculating period amounts, Oracle Fusion Projects performs the following steps:
Determines the number of days in the first and last period within the task assignment duration using assignment start and finish dates.
Determines the number of days in the other periods within the assignment duration.
Determines the total number of days for the duration of the task assignment.
Calculates the allocation factor for each period using the following formula:
Period Allocation Factor = Number of Days in Period / Task Assignment Duration
Calculates the periodic amount using the following formula:
Amount = Period Allocation Factor * Total Resource Cost or Revenue
In this example, a company uses an accounting calendar with periods that are identical to calendar months. A resource is assigned to a task for 121 days, from February 21 until June 21.
The following table shows how the task assignment days are determined, and the resulting allocation factors.

Distribution factors are prorated according to the spread points allocated to each period.
For example, if $100 is to be spread across four months for a planning resource that uses an even spread curve (where amounts are distributed evenly), then each period is assigned $25 each. That is, 10 spread points spread over 4 months equals 2.5 spread points per period. Each spread point has a distribution factor of 10.
The following is a description of how distribution factors are calculated for full or partial periods.
To continue our previous example: Say our planning resource was using a back-loaded spread curve rather than an even spread curve.
Note
Default distribution factors for a back-loaded spread curve are as follows: 0-5-10-15-20-25-30-35-40-45. Hence the total distribution for the spread curve is 225.
The following table describes how distribution factors are determined and amount allocated over the four planning periods.

Transaction start dates associated with a planning resource or task frequently do not coincide with the start or end dates of a period. In such a case, the actual number of planning resource or task transaction days determines how spread points and constituent distribution factors are allocated to full and partial periods.
Assume that the dates for a task assignment cover only 15 days of the first month (a 30-day month) of a four-month planning period. That first month represents the value of 0.5 spread points.
In such a case, the spread point value for each full period is calculated by dividing the total number of spread points (10) by the number of periods corresponding to the transaction (3.5). In other words, spread point values are as follows:
Full period : 10/3.5 = 2.8571
Partial Period: (10/3.5) * 0.5 = 1.4287
