Process documentation Production by Lot Size (30) Locate the document in its SAP Library structure

Purpose

This strategy is particularly useful for companies that mainly produce for major customers but who also require the option of selling smaller requirements from stock.

Example from Industry

Contract-based industries, such as automotive suppliers for spare parts.

Prerequisites

You must maintain the following master data for the finished product:

Process Flow

This graphic is explained in the accompanying text

For a detailed example of the entire process, see Sample Scenario: Strategy 30.

  1. Procurement is based on sales orders only. No planning for the finished product is involved. This means that you usually have to know the sales order situation in advance (which is why this strategy is sometimes combined with scheduling agreements) regarding replenishment lead times of the components and the production time. Alternatively, you can procure the necessary components by means of the following:
  2. · Individual planning of the components, for example using strategy 70. For more information, see Planning at Assembly Level (70).

    · Kanban components

    · Consumption-based components

    It is not possible to make use of information from other SAP planning tools here, such as forecasting, Sales Information System, SOP.

  3. An accurate availability check is performed according to ATP logic during sales order processing.
  4. Depending on the dates, several sales orders can be grouped together to be produced collectively in one single lot, using lot size optimization and/or rounding mechanisms. The lot size in this procedure depends on various aspects of production, such as pallet size or production optimization.
  5. Stock left over from previous procurement can be used for any other sales order. This is particularly useful for companies that mainly produce goods for major customers, but who also require the option of selling smaller requirements from stock.
  6. Planned independent requirements are not consumed by sales and stock orders. However the delivery 'consumes' the schedule lines or sales order items, because it updates them accordingly. If an issue is made for a particular sales order, the system reduces the sales order quantity. Stock orders are reduced when the goods are sold from stock.

Other Areas

Availability Check

You must maintain the ATP indicator (Availability check field in the material master) so that you can check with replenishment lead times. See Availability Check.
