Process models

Property × Yield conversion

In a previous release, the Auto Calculation option was introduced for Property × Yield predictions in Base + Delta models. This ensures that predictions of this type are recalculated automatically whenever the yield changes.

If you have models that use of the original Property × Yield calculation, you now have a single-click method to convert the original calculations to the new Property × Yield Auto format, as well as updating the numeric entries by dividing out the yield to only display the property values. To take advantage of the new method, enable the Property × Yield Conversion optional feature on the Features page under the File menu in the Model Explorer.

When this feature is enabled, the Convert Prop × Yld button is added to the Home ribbon tab when in the Predictions section of the Model Structure tab in the Process Units page of the Plan environment.

Click this button to convert the existing Property × Yield predictions to the improved Property × Yield Auto predictions in the selected process model, and to rescale all the delta values for the relevant predictions. The process model must be editable for the button to be enabled.

Converting to the new Property × Yield Auto format is optional. The original Property × Yield calculation method remains supported.

You are encouraged to try this feature and give feedback on the workflow and use case before the functionality is finalized in a future release. For more information about optional features, see the Manage Optional Features section in the Overview > Configure AVEVA Unified Supply Chain help topic.
