 Assembly Orders

Use

When creating a sales order the system can automatically:

  • Generate a network or

  • Generate an assembly order. Here it concerns the automatic generation of a planned order or production order to cover the planned independent requirements.

The strategy group in the material master defines whether an order/network is to be created in the background.

Prerequisites

The following conditions must be fulfilled for an assembly order to be created:

  • The Strategy group field in the material master (MRP) for the finished product must contain a strategy group that allows assembly orders.

  • The finished product must have a BOM.

  • The field Individual/collective in the material master (MRP) for the component should have the indicator Only collective requirements .

Features

Exchanging Data Between Sales Order and Assembly Order

The following data is copied between the sales order and the production order:

  • The material staging date and the order quantity are copied from the sales order to the assembly order.

  • The costs for the goods to be produced, the available quantity (in case an availability check has taken place) and the confirmed delivery date are copied from the assembly order to the sales order.

Scheduling

The sales order contains a desired delivery date. Scheduling is carried out automatically and a material staging date is calculated. The goods receipt processing time is subtracted from the material staging date. This generates the basic finish date of the production order.

Then the production order is scheduled backwards to determine the basic start date of the production order.

  • If the basic start date of the production order is not in the past then the desired delivery date of the sales order is confirmed.

  • If the basic start date of the production order is in the past then the order is rescheduled using today scheduling (see Parameters in Customizing ). A new basic finish date is calculated in the scheduling run. The goods receipt processing time is added to the basic finish date; then a further scheduling run is carried out to determine a delivery date that can be confirmed.
