Make-to-Order Repetitive Manufacturing (Non-Valuated Stock)
Purpose
You can use Repetitive Manufacturing in a make-to-order production environment. For each sales order item, the system creates one or several planned orders which directly reference the sales order item. The material is manufactured on the basis of the planned orders. Production is therefore triggered via sales orders.
If you are a repetitive manufacturer and work in a make-to-order environment with non-valuated sales order stock (see also:
Special case: Non-Valuated Make-to-Order Stock), the costs are collected and analyzed for the sales order item. Therefore, you require a
cost and revenue sales order item. This means, you carry out
Controlling for Sales Order. In this case, it is not possible to collect and analyze the costs at a product cost collector. The calculation of the stock value is carried out in a
results analysis. By
settlement which is carried out using the
results analysis data determined in the results analysis, you can activate the stock in Financial Accounting. 
You are recommended to work with
valuated sales order stock in make-to-order repetitive manufacturing. In this case, use the
product cost collector for make-to-order production as the cost object.
Prerequisites
Controlling Requirements Type Determination;
Checking the Requirements Type in the Sales Order).
You make the settings for the requirement type determination, requirement type, requirement class and account assignment type in Customizing for Sales Order Controlling under Controlling Make-to-Order Production.

The production version requires a BOM and a work center. If you want to represent several work processes, in Line Design, for example, you also need a routing.
Check Control Data for REM Profiles make the following settings:
standard cost estimate for a configurable material. Only by making this setting does the system automatically carry out an activity posting at the goods receipt for the sales order.
Process flow
To create the planned order when saving the sales order, you must have saved the assembly type "1" in the requirements class (Planned order: static procedure) or "4" (Planned order: dynamic procedure).
As the REM indicator is saved for the material to be manufactured in the material master record, the planned order has no conversion indicator. Therefore, the planned orders is not converted into either a
production order or into a purchase requisition.
Goods Receipt for the Sales Order,
Posting the Goods Receipt for the Sales Order). The system posts the actual costs to the sales order item, reduces the planned orders and updates the statistics.
Here, the sales order item is debited:

Instead of an automated activity posting, you can also carry out a direct activity posting manually.

It is not possible to use reporting point backflushing in make-to-order repetitive manufacturing. Total requirements, on the other hand, can only be used in make-to-order repetitive manufacturing.
