In Make-to-order production, which field controls planning of components as sales order specific stock?

In Make-to-order production, the planning of components as sales order specific stock is primarily controlled by the Individual/Collective indicator of the component. This indicator is essential as it specifies whether a component is planned individually for each sales order or collectively across multiple sales orders.

When the Individual indicator is set, this means that the component will be allocated specifically to a certain sales order, ensuring that inventory is tracked and planned in a manner that directly correlates with the needs of that order. This is particularly crucial in Make-to-order scenarios where products are manufactured only upon receiving a specific customer order, and therefore, each component must be closely monitored to meet the order's requirements.

The other fields, while important in the overall planning process, do not directly control this specific aspect of Make-to-order production. For instance, the Planning Strategy of the finished product dictates the broader approach to production planning, the item category in the BOM is used to define characteristics of the components, and the MRP Type indicates how the material will be handled in terms of planning and scheduling. However, none of these factors are as directly tied to the concept of individual component allocation to specific sales orders as the Individual/Collective indicator is.
