A discovery model is normalized based on three attributes “Discovered Publisher”, “Discovered Product” and “Discovered Version”

A normalization mapping is created based on the concatenation of value/string of “Discovered Publisher”, “Discovered Product” and “Discovered Version”, if there is any change in the discovered string, it will require a new normalization map

Is it possible to share a screenshot that shows “Discovered Publisher” too
