Understanding the Net Change Processor Business Service

The Net Change Processor business service (J0000020) handles net change processing for both fields and value objects. The utility processes changes depending on which method is called:

• Net Change by Field

  The Net Change Processor utility determines the value of a field to use to update an entity. If you do not specify a new value for a field, the utility preserves the current value.

• Net Change by Value Object

  The Net Change Processor utility determines the value of all of the fields within a value object to use to update an entity. If you do not specify a new value for a field within a value object, the utility preserves the current value of the field within the value object.

Blank and zero are valid values for fields in the input object, and the utility preserves these values. If a field in the input object has a null value, the utility replaces the null value with the current database value.
