17.2.8 Composition of the Basic Master Data Objects

Intended learning outcomes: Explain the breakdown of the master data into individual classes and their associations using the example of the ball bearing. Describe the basic object classes for planning & control.


Figure 17.2.8.1 shows, by way of example, a breakdown of the master data for the ball bearing shown in Figure 17.2.1.1 into the four most important classes, namely, item, bill-of- material position, work center, and operation. The arrows point to the associations between the logistical objects discussed above, that is, to:

  • Figure 17.2.3.9 between the item and the bill- of-material position that determines the “pro­duct « component” connection between two items. These connec­tions are “as a product, consists of” (product viewpoint)or “as a component, is used in” (component viewpoint), depending on which side we start with. See Figure 17.2.3.2. They emerge from break­ing up a reflexive n-to-n association according to Section 20.3.8.
  • between the item and work center to the operation (see Section 17.2.6). These connections are “is produced by” (product viewpoint)or “as a work center, is used in” (work center viewpoint), depending on which side we start with.

Figure 17.2.8.2, as a generalization of Figure 17.2.8.1, shows all the funda­men­tal logistical object classes for the master data, together with their as­so­cia­tions, for products with a convergent product structure. The represen­ta­tion corresponds to the type of data model used in ERP software today.

Depending on how it is organized, the master data are administered partly by a central standardizing committee and partly directly by the sections in which the data concerned arise, that is, design or production equipment.

It should be noted that the objects relating to production equipment are similar to the objects relating to the item (see Section 17.2.7). Collective tools or toolkits and their tool bills of material behave in the same way as products and their bills of material. Their use in operations, however, is similar to the use of a work center.



Course section 17.2: Subsections and their intended learning outcomes

  • 17.2 The Master Data for Products and Processes

    Intended learning outcomes: Describe master data of products, product structure, components, and operations. Explain the data structure of item master, bill of material, and where-used list. Disclose the data structure of work center master data, the work center hierarchy, as well as for operation, routing sheet, production equipment, bill of production equipment, and bill of tools.

  • 17.2.1 Product, Product Structure, Components, and Operations

    Intended learning outcomes: Present the concept of master data. Explain the production order as a collection of master data. Describe a simple product structure. Identify the intermediate product used simultaneously as a component in higher-level products.

  • 17.2.2 Item Master Data

    Intended learning outcomes: Present the concept of the item master record. Describe the attributes of the technical information and the stockkeeping information of the item master record. Identify attributes of the item master record for information on costs and prices.

  • 17.2.3 Bill of Material, Bill-of-Material Position, Where-Used List, and Where-Used-List Position

    Intended learning outcomes: Present the concepts of the bill of material and of the bill-of-material position, the where-used list, and the where-used list position. Differentiate between the single-level bills of material, the multilevel bill of material, and the summarized bill of material. Differentiate between the single-level where-used list, the multilevel where-used list, and the summarized where-used list. Describe the bill-of-material position logistical object and its most important attributes.

  • 17.2.4 Work Center Master Data

    Intended learning outcomes: Present the work-center business object. Describe the attributes of the work-center master record relating to capacity, concerning costs, and for calculating the lead time.

  • 17.2.5 The Work Center Hierarchy

    Intended learning outcomes: Present the concepts of workstation and cost center. Explain the work center hierarchy.

  • 17.2.6 Operation and Routing Sheet

    Intended learning outcomes: Present the concepts of the operation business object in association with the routing sheet. Describe the most important attributes of the operation master object. Produce an overview on the work center where-used list.

  • 17.2.7 Production Equipment, Bill of Production Equipment, and Bill of Tools

    Intended learning outcomes: Present the concepts of bill of production equipment and bill-of-production-equipment position as well as production equipment where-used list. Produce an overview on collective tool, bill of tools, bill-of-tools position, and tool where-used list.

  • 17.2.8 Composition of the Basic Master Data Objects

    Intended learning outcomes: Explain the breakdown of the master data into individual classes and their associations using the example of the ball bearing. Describe the basic object classes for planning & control.
