To set up a make-to-order planning scenario for a finished material, you need to choose planning strategy 20 (Make-to-Order) and select the corresponding Individual/Collective indicator for the components in the bill of material. This way, you can control whether the components are procured individually or collectively for the sales orders. The following steps explain how to achieve this:
In the material master record of the finished material, you need to select the MRP type PD (MRP) and the strategy group 20 (Make-to-Order) in the MRP 1 view. This means that the finished material is planned based on the sales order requirements and not on the forecast12.
In the bill of material of the finished material, you need to select the Individual/Collective indicator for each component. This indicator determines whether the component is procured individually for each sales order or collectively for all independent requirements. For the component that should be procured for each sales order individually, you need to select the indicator 2 (Individual requirements only). For the component that should be procured jointly for all independent requirements, you need to select the indicator 1 (Collective requirements only)3 .
When you create a sales order for the finished material, the system generates a sales order item and a planned independent requirement for the finished material. The planned independent requirement is used as a planning element in MRP and triggers the procurement of the components according to the Individual/Collective indicator. For the component with indicator 2, the system creates a dependent requirement that is linked to the sales order item. For the component with indicator 1, the system creates an independent requirement that is not linked to the sales order item .
