I have configs in a family of parts that have different materials.
Every time I change a Material from one of the configs, when I come back to the Excel table of the part family, I find an "*" in front of all the other materials
Thanks @gt22, the video is interesting but I just wonder why SolidWorks reacts like this, i.e. that by changing a material of a config, the other configs take a star in front of their material
