Hi, as always there are different approaches possible. Some collect the data in the cube and calculate the eliminations in there. The approach I like the most is the Register-based approach. You can set up your custom table or use a marketplace solution where you collect the data, calculate the eliminations based on that and post or load the eliminations into the cube. I like this approach as you can also store the calculated data in a table as well to provide full transparency of your inventory to drill back to or to analyze before posting the eliminations. This is typically used for long term assets, but I guess you can just as well configure this for your inventory as well.
This all very much depends on the exact requirements, so the value of my comment may be limited.
