Define blending specifications for your case

Each product in Plan is a traded material, and is defined by the allowed range of property specifications for that material in a particular market. Specifications are normally configured on a global basis in the Model Explorer. Individual criteria can then be overridden in cases in the Blending > Specifications grid.

Note: The Specifications tab shows the outputs from the model as a whole during the planning period. This differs from the Blend Detail tab, which shows the output for a specific blender.
Values for a given product may differ between the two tabs, for example if additional inventory of the product is available in the plant.

Note: TBP interpolation
If you create a property specification for true boiling point (TBP) at a certain percentage, and that TBP property is not specified for one or more streams upstream of the blender, the input TBP for the blender is calculated by interpolating the cumulative yields at those temperatures available for all input streams.
For more information see TBP blending in Plan.
