We have something called "Cluster" item.
Three to four stock materials (components) are assembled together and sold as a "CLUSTER" item. These stock materials have a material number. The CLUSTER item also has a material number.
Price control for stock materials is V and for Cluster item it is S. We maintain a BOM for CLUSTER item. The stock materials are the components.
CLUSTER items do not have production orders and currently we are not costing them. Stock materials are trading items and they are also sold independently.
Issue
When we sell the CLUSTER item, since the CLUSTER ITEM has no cost, the cost of goods sold for Stock materials is getting debited. Whereas Sales revenue is getting booked to the CLUSTER ITEM.
Billing Doc

The item 300 is the CLUSTER item the other items following that are the Components
Cost of Goods Sold

The cost is getting recorded for the components. It is the Quantity in the invoice multiplied by the Moving average price at the time of sale.
Sales

Requirement
We want the cost of goods sold to get booked to the CLUSTER item and NOT to the Component material.
Please advise.
