Saving of Formula View Data in the Property Tree

Use

You can save the calculated data or manually entered data for most formula views in the property tree . The data is saved in the property tree for the substance of the primary output if the primary output is a substance, and in the property tree for the formula if the primary output is a stream.

Also, the system automatically saves the data for the Input and Output formula view in the property tree for the formula when the recipe workbench is in edit mode and you exit the Input and Output view.

Prerequisites

  • You are authorized to change the data of the primary output or the formula.

  • In Customizing for the Environment, Health and Safety component in the IMG activity Specify Value Assignment Types , you have created the value assignment types in which the data for the formula views is to be saved.

  • In Customizing for the Environment, Health and Safety component in the IMG activity Set Up Property Trees , you have assigned the created value assignment types to the property tree of the primary output or the formula.

  • In Customizing for Recipe Management in the IMG activities Specify Parameters for Explosion Scope and Define and Assign Values to Environment Parameters , you have specified the created value assignment types at the relevant places.

Features

The following table shows which data the system saves in the property tree when you choose the corresponding function in the formula view:

Formula View

Data Saved in Property Tree

Usage with Which Data Saved

Input and Output

Density

Density (aeration)

Proportion of total solids

Default usage for view, that is, the usage you specified in Customizing for Recipe Management in the IMG activity Specify Formula View Parameters

Composition

Composition data

Default usage for view, that is, the usage you specified in Customizing for Recipe Management in the IMG activity Specify Formula View Parameters

Nutrients

Composition data for all nutrients for the reference quantity 100g before losses are taken into account

Usage on whose basis the system performs calculations (is equivalent to the data source specified in the Data Source field)

Diet Suitability: Summary

Values of all diets

Usage on whose basis the system performs calculations (is equivalent to the data source specified in the Data Source field)

Key Figures

All key figures

Default usage for view, that is, the usage you specified in Customizing for Recipe Management in the IMG activity Specify Formula View Parameters

We recommend that for the default usage for the view, you use the same usage as that with which the system also determines the key figures.

Costs

Usage you selected in the view

If the system has calculated an evaporation or absorption in a composition, it does not transfer it to the composition to the property tree. In the same way, it does not transfer streams to the composition in the property tree. A warning is then displayed.

If the primary output of a formula is a stream, the system uses the data it calculated in the Input and Output formula view for the total solids and density. If these calculated values change, this affects all formulas in which the stream is used as the input. Therefore, the system recalculates all subsequent stage formulas in the recipe.

In the property tree, you can only enter compositions to an accuracy of four decimal places. A higher level of accuracy is possible in the formula. This means that there may be a loss of accuracy when formula data is transferred to the property tree. With the Business Add-In (BAdI) Conversion of Formula Data to EH&S Data , you can convert the data to be transferred into other units and thus prevent or at least reduce losses of accuracy when saving data in the property tree.

Activities

To save the data for a formula view to the property tree, in the formula view choose with the quick info text Transfer to Spec. of Pr. Output .
