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:
Fig. 17.2.8.1 Breakdown of the master data into individual classes and their associations using the example of the ball bearing (see Figure 17.2.1.1).
- 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, 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.
17.2.1b The Intermediate Part
Intended learning outcomes: Identify the intermediate part 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.
17.2.3a Bill of Material, Bill-of-Material Position, and Where-Used List
Intended learning outcomes: Present the concepts of the bill of material, of the bill-of-material position, and the where-used list.
17.2.3b Single-Level Bill of Material, Multilevel Bill of Material, and Summarized Bill of Material
Intended learning outcomes: Differentiate between the single-level bill of material, the multilevel bill of material, and the summarized bill of material.
17.2.3c Single-Level Where-Used List, Multilevel Where-Used List, and Summarized Where-Used List
Intended learning outcomes: Differentiate between the single-level where-used list, the multilevel where-used list, and the summarized where-used list.
17.2.3d The Bill-of-Material Position and the Where-Used-List Position as a Logistical Object
Describe the bill-of-material position and the where-used-list position as logistical objects. Identify 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 operation business object in association with the routing sheet. Describe its attributes. Identify 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.
