Defining the Master Data in the Design to Operate Process


After completing this lesson, you will be able to:

  • Explain the master data need in design to operate process

Material Master Data Record

The material master data is subdivided into views. The basic data view displays data defined at the client level, and all other views are defined at plant level.

A material master contains global data and plant-specific data. Global data is valid across all plants. An example of global data is data that is the same for a material in all production plants. Plant-specific data contains settings for the relevant plant, such as a specific production plant. General data, such as the measurements and weight of a material, is set globally, whereas settings for planning are predefined locally. This data may differ depending on the plant.

Bill of Material

Bill of Material (BOM)

BOM contains the assemblies, or components, which are to be included in the production of a material. BOMs are used in MRP, production, procurement, and for product costing.

A BOM consists of a BOM header and BOM items. The base quantity in the BOM header specifies the amount of the finished product to which item quantities refer.

BOMs are single-level. An item of a BOM can contain components. In this way, multi-level production is described using the single-level BOMs of the finished product, the assemblies, and, where required, using the BOMs of the assemblies.

In addition to stock items required for the finished product, a BOM can contain documents and text items.

BOM Structure

The settings in the BOM header apply to the entire BOM. BOM usage determines the business applications for which a BOM can be used. The status of the BOM controls whether the BOM is active for particular applications (for example, MRP).

The components necessary for the production of the finished product are entered as items of the BOM. The item category specifies the type of item you are using.


Routing and BOM

Production Versions

Work Centers

In a plant, operations or activities, are carried out at a work center. Therefore, a work center specifies where production ultimately takes place.

Work centers are used in the following applications:

  • Routings
  • Networks
  • Inspection Plans
  • Maintenance Routings

A work center can be a specific geographical location in the plant. For example, a specific machine or department in a plant.

Work Center Data

The data of the work center is assigned according to thematic views. The work center stores the available capacity of that particular work center and the data needed to calculate the costing of work completed.

The default values define the data that has to be transferred into the operation of the routing or used as a reference. By entering a standard value key, a resource is assigned standard values for operations in routings, rate routings, master recipes, and production or process orders to be executed at this resource.

A standard value is a planned value used to carry out an operation, such as execution time.

Standard values are used in costing, scheduling, and capacity requirements planning to calculate costs, execution times, and capacity requirements.

You can enter default values for the operation to be executed at a resource. When you maintain the operations in the routing, rate routing, master recipe, and production or process order, the system copies and refers this information.

By assigning a cost center to a resource, you link the resource to cost accounting, and can then carry out product and order costing. You can define the specific output of a resource by assigning activity types assigned to this cost center to the resource.

Available capacities of resources are the basis for scheduling process orders, and are required for capacity-requirements planning and shop floor control. To calculate the execution of an operation during process-order scheduling, the available capacity of exactly one of several possible resource capacities is defined as the basis for scheduling. To calculate costs, execution times, and capacity requirements of phases carried out at a resource, you need to enter a suitable formula key on the corresponding screens.
