You create a production lot number for every machine that is to be produced (in this case, the production lot represents a machine number).
You maintain part of the WBS BOM in order to reflect the main parts of the final assembly.
You create planned orders with quantity equal to 1 for each production lot and enter the account assignment category Q and the WBS element (production lot number) in the account assignment data.
You carry out the MRP run.
Purchase orders, transport orders and production orders are posted as actual values. This causes the status of the machines to change to work-in-process.
A sales order is received. When entering the sales order into the system, you also enter the production lot number.
You create the WBS BOM and the routing with reference to the production lot number (WBS element) in order to enable customer requirements to be taken into account.
The production order for the final assembly is completed and you post the goods receipt to the individual project stock of the production lot.
For the delivery, you post the goods issue from the individual project stock to the sales order.
The costs for the production lot are collected using conventional cost determination for WBS elements.
