The current behavior of D365F&O:

You have a product configuration model created with Attribute types size, color, and type. Customer has enabled include in reuse only for color and size.

When you create a sales order with 2 lines with the same item number and the same configuration except for the “Type” value, number sequence value is the same in the configurationID.

What happens is, configuration nomenclature is the same (and also the number sequence) but when you open the configuration for the second line, “Type” value has been changed to the one belonging to the first line’s configuration.

The Idea:

Existing configuration Shall remain the same when not all attributes are included in reuse.
