Example

The following sample C# code illustrates how to define, query, and use the wwActualChars object.

The example populates a list of ingredients, populates a list of units to which the material has been assigned whenever a material is selected, populates a list of lot tracking information defined for the selected unit, and finally populates a list of actual characteristics for the selected lot tracking instance. The global variables are defined so that they are available throughout the entire program.
