Attention: For information on how to use the Selected and Secure checkboxes of these options, see Using the Selected and Secure Checkboxes.
Field Description
Spread ETC according to This field provides you with two options for statistical forecast spreading:
  • Existing ETC spread: Select this option to base the forecast spread on the existing forecast spread when performing forecast calculations.
  • Budget: Select this option to base the forecast spread on the current budget spread when performing forecast calculations.

    Cobra uses the value of this option if you run the Calculate Forecast API process and do not include in the SpreadETCMethodId setting in the API script.

    Cobra displays an error if the Secure checkbox for this option is selected and the value of this setting does not match the value of the SpreadETCMethodId setting in the API script.

Allow negative ETC Select this option to instruct Cobra to calculate all negative Estimate To Complete (ETC) values. Otherwise, Cobra sets all negative ETC values to zero.

Cobra uses the value of this option if you run the Calculate Forecast API process and do not include in the AllowNegativeETC setting in the API script.

Cobra displays an error if the Secure checkbox for this option is selected and the value of this setting does not match the value of the AllowNegativeETC setting in the API script.

Scale retain EAC This field provides you with three options for scaling Estimate At Complete (EAC) values.
  • None: This is the default selection. Selecting this option instructs Cobra not to scale the EAC to a particular value.
  • Currency: Cobra uses the value stored in the EAC field in the control account/work package pane of the Project view to calculate the forecast further so that the total EAC currency value is equal to the EAC field value. When this option is selected, you can edit the EAC by selecting Update EAC from the shortcut menu in the Project view.
  • Hours: Cobra uses the value stored in the Hours.EAC field in the control account/work package pane of the Project view to calculate the forecast further so that the total EAC hours is equal to the Hours.EAC field value. When this option is selected, you can edit the Hours.EAC by selecting Update EAC from the shortcut menu in the Project view.
  • Hours and Currency: This option is a combination of the Hours and Currency options. As Cobra calculates the forecast, the resource assignments whose first result is Hours are scaled so that the total hours match the value stored in the Hours.EAC field in the control account/work package pane of the Project view. The resource assignments whose first result is not Hours use the EAC_NONLAB field to calculate the forecast further so that the total currency value EAC is equal to the EAC_NONLAB field value. When this option is selected, you can edit the Hours.EAC and EAC_NONLAB by selecting Update EAC from the shortcut menu in the Project view.

    Cobra uses the value of this option if you run the Calculate Forecast API process and do not include in the ScaleRetainEACId setting in the API script.

    Cobra displays an error if the Secure checkbox for this option is selected and the value of this setting does not match the value of the ScaleRetainEACId setting in the API script.
