Object documentationValue Assignment Category Composition

 

Lists the ingredients of a specification with their concentrations or quantity data.

Example Example

Ingredients are substances that are still present in a substance after the manufacturing process has finished.

End of the example.

 

Individual value assignment types are assigned to the value assignment category Composition. These value assignment types can be sorted into groups in the property tree. The value assignment types can be set up based on the following criteria:

  • Type of composition components

  • The accuracy of the quantitative values

In the standard system, the composition is shown as a table (ALV grid control).

Example Example

Typical value assignment types of the category Composition are:

  • Exact chemical composition

  • Exact composition from products

  • Composition according to TSCA (Toxic Substances Control Act)

End of the example.

Structure

If you activate the Total pushbutton, the total for the components in a row is displayed at the end of the table and in the title bar. If you have chosen dimension PROPOR (weight proportion or volume proportion) as the reference value, a message is also displayed in the title bar indicating the percentage by which the sum of components exceeds or falls short of 100%. If the Total pushbutton is not activated, the total for the components is not displayed at the end of the table. The information is still displayed in the title bar.

Note Note

If you choose dimension PROPOR (weight proportion or volume proportion) as the reference value, a message is displayed in the status bar if the total exceeds 100%, assuming you have changed the values for the composition. If you save the change, a warning message is displayed.

If the Total pushbutton is not activated, messages are not displayed in the status bar and the total is not displayed at the end of the table.

If different units of measurement of a dimension are specified for the components, an SI unit must be assigned to the dimension. If no SI unit is assigned, the sum of the components cannot be calculated.

End of the note.
