Generate list based on product of variables

Hi All,

I'm working on mapping the process flows and estimating the expected activity durations at a manufacturing plant.

I started by listing all the different product variations that would affect the routes and/or durations and came up with this (manually) for one group of products GGC Variations.PNG Variations List.PNG

Now I need to create another list for a different group of products, that have a total of 6912 variations. See attached BV Variations.PNG

I don't have any experience with vba but I figured there must be an easier solution than listing each variation manually. Can someone help me out with this please?
