In certain industries, like steel, cable, paper, and textile industries, the same operations are used to manufacture different products. These operations may include producing a melt, continuous casting, and hot and cold rolling. Or in cable industry operations like Rod breakdown, wire drawing, inner sheathing, outer sheathing, the operations before and after these identical operations are different for different products.


The order combination function allows you to combine the sequences of identical operations in a consolidated production order. We can combine the sales orders, planned orders and production orders. Via the order combination we convert an item for a sales order into a production or process order

This provides all the benefits of optimized planning, along with additional parallel specification of structured stocks objectives. A single optimization of the job order regarding the agreed deadlines results in a large product.

When we combine sales orders, all procurement elements and the open quantity for customer special stock are proposed for combination. In this case, the open quantity is the quantity not covered by procurement elements, such as planned or production orders.

We can use order combinations whenever the orders are the same or similar. The orders can come from different sales order stocks. However, you should not plan to include semi-finished products, which can be combined.


The way  of scheduling is based on practice-oriented stocks levels and structures. When you use an order combination, the aim of the scheduling is to meet the dates in accordance with the original orders. For the combined order, the system always uses backward scheduling.


First, we need to select the original orders we want to combine.  We need to define one of the selected orders as a reference order. As soon as we have selected the orders, a new production order is created using the master data of the reference order. This new order is the combined order. In order to create the original orders as items in the combined order, the system determines the first item category.

After the combined order has been created, the system checks the selected original orders and operations.  Possible changes include changes to the order quantities or dates. We can add original orders to the combined order or delete them from it at a later stage.  We can also cancel the entire combined order.


The default quantity for the original order X in the confirmation can be calculated as,

Order X Default Quantity  = {Order X Open Production Quantity / Open production quantity in original order  } X Quantity to be confirmed for combined order.

The best practice in Mill products is that the semi-finished or finished materials or products when they are put to stock use the batch concept to carry the actual confirmation as batch. When determining the work in process , the system values each production order (original orders and combined orders) separately.
