Planning Process Flow of Production Lots

Purpose

The process describes the procedures for planning production lots.

Prerequisites

In order to be able to carry out production lot planning, you initially have to maintain the following master data:

In the material master, you define the necessary settings in the MRP data.

You create a number for each individual production lot. The system creates a WBS element during the creation. See also: Creating the Production Lot Number

If the BOM for the production lot is different from the BOM usually used, you create a Work Breakdown Structure BOM with reference to the production lot number (WBS element).

If the Routing for the Production Lot is different from the normal routing, you create a routing with reference to the production lot number (WBS element).

General Process Flow in the R/3 System

1. There are two possible methods for determining the planned independent requirements for a production lot:

You can carry out flexible planning (sales and operations planning) for a production lot and then transfer the planned quantities to Demand Management by entering the production lot number.

You can enter the Planned Independent Requirements directly into Demand Management with reference to the production lot number.

2. You then create a Standard Cost Estimate for the Production Lot. The calculated value forms the basis for the valuation of stock.

3. You carry out the MRP run. The system creates planned orders and purchase requisitions with reference to the production lot for the material to be planned and all components. The number of the production lot is displayed in the procurement elements in the WBS element field.

For each production lot, the system opens an individual project stock with the number of the production lot (WBS element). These are displayed in MRP Evaluations as individual segments.

4. You convert the planned orders and purchase requisitions to production orders and purchase orders. The reference to the production lot number remains unaffected.

5. You produce the production lot. For the production, you can work with production order management or with repetitive manufacturing.

6. After the production, you carry out backflushing for the production lot number.

7. For a production lot, which is to be transferred to the plant stock, you post the complete part from the project stock to the plant stock.

With a production lot with sales order stock, the materials also remain in the project stock of the WBS element even after production has been completed.

8. Incoming sales orders can be covered by plant stock if the material in question was posted to the plant stock.

With materials from sales order stocks, you have to enter the production lot number (the WBS element) in the sales order item. The sales order can only use materials from the corresponding project stock. The same applies if you create a PS network for a sales order. The requirements can also only be covered by certain individual project stock (stock of the production lot).
