HI,
Make-to-Order Production (20)
Purpose
In make-to-order production, a product is produced specifically for an individual sales order. This planning strategy is used when planning of the (parent) product is not required or not possible. Neither Demand Management is involved in this process, nor is there an allocation mechanism. Orders are taken as they come. This strategy represents a production procedure in which each product is only produced once, although over time the same or similar production processes are repeated. Each product is specifically produced for an individual customer so that the finished product is rarely placed in stock.
Prerequisites
You have the following two options.
Be able to do the following:
Procure all necessary components within the total replenishment lead time
Plan on component level
Use consumption-based components or Kanban-based components
Receive the sales orders at a very early stage with regard to the replenishment lead time.
You also must maintain the following master data settings for the finished product:
Strategy group 20 on the MRP screen
Item category group (such as NORM) on the Sales Organization screen
No specific product structure is required. This means it does not matter if the material has a BOM (internal production) or not (and is procured externally). The material is, however, usually produced in-house as in the subsequent sample scenario.
Process Flow
For a detailed example of the entire process, see Sample Scenario: Strategy 20.
1. The sales order quantities are planned for production using the sales order number. The quantities produced for the individual sales orders cannot be changed. Each quantity is maintained specifically for the individual sales order. A separate segment is created in the MRP list for make-to-order production.
2. Starting from the sales order, you can apply this type of planning to as many levels of the BOM as you want. Assemblies and components are produced or procured specifically for the pegged order and stock is managed separately for this sales order.
3. The production and procurement costs are maintained for each sales order in either a settlement order or in a project at sales order item level. This ensures a detailed analysis of the planned and actual costs.
You can also use this production technique to create "assembly orders." The assembly order triggers the creation of a production order or of a planned order and provides you with a precise delivery schedule. The delivery schedule is based on availability and the production requirements of the relevant assemblies and components.
Strategy 21 is used for PS & SD
Assign Sales Orders to Project
SAP has predefined strategy group 21 (with strategy 21) for the link between sales documents and projects.
Hope this will help you.
