A production order is an internal order for the production of a defined quantity of a product (or many products).

 

Structure

Therefore, a production order consists of one or more order-related BOMs that are produced from the master BOM. Because order-related BOMs are copies of the master BOMs, they can also be changed order-related (material usage and quantity) without affecting the master data.

 

Primary- and secondary requirements

Order-related BOMs can be either primary or secondary. Primary BOMs produce finished products. Secondary BOMs are preceding production stages, the so-called semi-finished products. If these secondary requirements are to be manufactured order-based (not stock-based), then a production order contains both BOMs for the primary and the secondary requirements. In addition, these order-related BOMs are linked to each other by the retrograde BOM explosion, which is then referred to as "built to order" production. An order-related BOM is quasi a sub-order of a production order. If the following is referred to as an order-related BOM, then the sub-order is meant.

 

Built to order

The "built to order" production also has an effect on the automated process: materials or semi-finished products that have been manufactured with a production order so that they are used as a input-material in the subsequent order-related BOM cannot be used in other production orders as input-material. However, in stock-based production is this possible.

 

Batch production (process technology)

The production of a material that is produced from an order-related BOM can also be carried out batchwise (term from process technology and does not apply to discrete production). The order size is divided into smaller sub-quantities due to the limiting machine capacity. Each subset/batch is carried out through the production line in turn. 

A batch is usually given a lot number. However, several batches or the entire order-related BOM can also refer to the same lot if a more detailed level of detail is desired due to the batch tracing. Conversely, a batch can also create several lots (so-called "partial lots") if a high level of detail is required due to the batch tracing.

 

Delimitation of the terms Batch / Batch stock / Lot in Variobatch:

• The term batch is used as long as the product is in the production process (unfinished, production-oriented view).
• After the product has been manufactured and is stored we speak of a "Batch stock" (finished, material-management view). The smallest identifiable quantity of a batch in a storage bin is called Quant(um). Quants and batches, which can have economically different material numbers, but from a production-technical point of view have exactly the same characteristics are called Lots.
• The Lot is similar to a bracket that includes one or more batches. You use a lot to set the focus of batch tracing.

(Attention: See differences to Wikipedia.)

 

The data of a production order and the order-related BOMs is distributed over five tabs:

1. "BOM Info": Information about the referenced master BOM and the order size
2. "Components": Materials used in intermediate products as input materials.
3. "Intermediate products": Posting of input materials and output, batch generation
4. "Batches": About generated batches
5.  "Workflow": Configuration of workflow nodes

The comboboxes in the Explorer list (A) are used for quick filtering.

 

In order to create a production order, you must perform the following work:

1. In material management, materials must be created for the material list (components, Input) and for the resulting product (output).
2. One or more BOMs must exist.
3. Storage locations and bins must be created and must exist in stock.
4. Optional: Workflows must be created for a order-related configuration of a workflow.
