Hi, 'I am trying to find a way to subdivide the columns into different groups but allowing them to be in multiple gropus at the same time or being able to filter them easily. Lets say I have multiple suppliers for steel and aluminum and i want to be able to analyze only certain suppliers or i want to analysze all the parts made with steel no matter who the supplier is or by process. this would be used for a much much larger number of suppliers and products.
Thanks
