About Using the Spread Option for Cost Projections
When entering projections in the PM Cost Projections form, the spread determines how plugged values entered on the projection code are distributed to the phases/cost types.
When you set a spread option for projections in PM Company Parameters, the selection is applied to all of the projections made in that company. The following describes each of the options.
Prorated
If you select Prorated, the plugged amount is distributed based on a weighted average of the percent complete units on the phases/cost types associated with the selected projection code (in PM Projection Codes).
For example, assume a projection code is associated with three phases and each phase is associated with the same cost type.
Phase |
Cost Type |
---|---|
1000- |
6 |
1001- |
6 |
1002- |
6 |
When a projection is then entered on the projection code in PM Cost Projections, assume the Phase/Cost Type tab contains the following information.
Phase |
Cost Type |
Percent Complete Units |
---|---|---|
1000- |
6 |
30 |
1001- |
6 |
40 |
1002- |
6 |
80 |
Total units |
150 |
If 200 units is entered in the Percent Complete Units field on the Grid tab of the PM Cost Projections form, the 200 units will be distributed to the Phase/Cost Types tab in the following way.
Phase |

( 80 /150 ) * 200 |
106.6666666666667 |

200 |
Defined at projection code
If you select Defined at projection code, the plugged amount is distributed to the phases/cost types based on the spread percentage set up on the projection code (PM Projection CodesPhase/Cost Type tab, Spread % field).
For example, assume a projection code is set up with the following phases/cost types.
Phase |
Cost Type |
Spread % |
---|---|---|
1000- |
6 |
20 |
1001- |
6 |
30 |
1002- |

50 |
If you enter 200 units in the Percent Complete Units field on the Grid tab of the PM Cost Projections form, the system will A distribute the 200 units in the following way.
Phase |
Cost Type |
Calculation |
Percent Complete Units |
---|---|---|---|

60 |
1002- |

50% * 200 |
100 |
Total units |
200 |
Modify How Plugged Values are Distributed
When you enter a plugged amount on the projection code, the plugged values are distributed to the phases/cost types based on how you configured the spread. However, you can also change how plugged values are distributed, for example, if you need to change how a variance is spread to the phase/cost types when the projections are being entered.
For instructions about modifying the distribution for plugged values, see Modify Plugged Amount Distributions for a Projection Code.
