I'm having a bit of an issue when it comes to updated product sku numbers in Tableau. Basically, we have hundreds of skus, and about 15 of them were updated (due to changes in packaging... branding etc..), but I want to look at them as if they were still just one sku since we still have many of the old skus out in stores selling. So basically, I want to take a handful of skus out of hundreds and and combine old and new sku to get combined figures. For the unchanged sku's nothing should change. I would want to be able to drag this in just like any other dimension. Is this possible with groups or something?
You should be able to do this relatively easily with groups. To create a group, right click on the pill you want to group and select "Create > Group...". Once the grouped field is created with the combined SKUs, use "Replace References..." to swap out your original field for the grouped one.
