How your plug account in this example show the figure of 5000 cos in Holding entity only you are recording Intercompany revenue of 20000 and Intercompany Cost of 15000? Intercompany cost of 15000 should be recorded in Subsidiary company then but since complete Inventory in your example is unsold so No Intercompany cost of sales will be recorded in Subsidiary entity and then in that case plug account should show 20000 which was Intercompany revenue. In your excel sheet- In Holding books Instead of Intercompany Cost of Sales (it should be Regular COGS) since for Holding entity its not Intercompany Cost. Please comment.
