I've been looking for an answer to this issue, and this post is as close as I could get.
How can I show the volume of a component in the Component Attributes window? It seems to be available in Attribute Reporting and in the Entity Info window, but I haven't been able to figure out how to get it to the CA window.
Once I have the volume, I hope to calculate a cost for that volume. I have the cost per a determined UOM and can figure out how to convert it.
