Hi,
If you have same attribute name in you reference-data objects and products the History in a product will look like the values from the reference-data object replaces the product values.
The attributes to the left belongs to the product and the attributes to the right belongs to the reference-data object. This comparison is wrong, since it should only compare attributes belonging to the same object.
E.g the code from the product and code from the reference-data object are colliding.
