Plant Maintenance Master Data

Business Background

By mapping your operational structures to technical objects, you can efficiently manage and evaluate your technical assets and maintenance objects and monitor the costs involved. Structuring the existing technical systems on the basis of technical objects reduces the time required for managing the technical objects and allows a faster evaluation of maintenance data.

A functional location represents an area within a system or plant where an object can be installed. Functional locations are created in hierarchical structures and thus allow a spatial, functional, or process-oriented structuring of your systems. Individual maintenance objects are represented by pieces of equipment that are installed in functional locations. The usage times of a piece of equipment at a functional location are documented over the course of time.

Key Feature Use

Structuring Technical Objects Hi­

erarchically and Horizontally

The functional location is an organizational unit that structures the maintenance objects of a company according to functional, process-related, or spatial criteria. When creating a functional location and defining its place in the hierarchical structure you define where a piece of equipment can be installed. Pieces of equipment can be installed in different func­

tional locations or in other pieces of equipment.

As functional locations represent your company's operational structures, they are usually part of a hierarchical structure and you can summarize costs or other maintenance data for individual hierarchy levels. Based on the structure indicator, functional locations are au­

tomatically arranged in the structure when you create them. You can also create hierarchi­

cal equipment structures if you want to divide large pieces of equipment into smaller units.

If you want to structure your technical systems horizontally, you can create object net­

works. Object networks are represented by links between various pieces of equipment or functional locations.

Creating Master Records for Functional Locations and Pieces of Equipment

Once the structure of the asset is defined, you can create a master record for each func­

tional location and piece of equipment and specify general data, location data, organiza­

tional data, and structure data as well as edit classification data and characteristic values, and assign documents.

● You can assign a bill of material (BOM) to the master record of a functional location or piece of equipment.

● After having created characteristics and classes, you can assign this classification in­

formation to the master records of equipment and functional locations. If you have to manage a large number of objects, the classification enables you to easily locate your objects and group them together for evaluations.

● You can serialize a piece of equipment by assigning a material number and serial num­

ber to it. This makes inventory management possible for the equipment.

● A piece of equipment that is installed in a technical object can store the history of its installation location. The system records a usage period for each installation location, enabling you to track the complete installation history.

● You can maintain fleet information, such as data pertaining to the engine and fuel, in the equipment master record.

You can represent objects that are not repaired but rather exchanged in case of a break­

down by creating master records for materials and assemblies. Although this does not en­

able you to document a maintenance history, a material or assembly can also serve as a reference object for a maintenance notification or order.

Key Feature Use Creating Maintenance Bills of

Materials (BOMs)

A maintenance bill of material (BOM) is a complete, formally structured list of the compo­

nents making up a technical object or an assembly. Maintenance BOMs support you when locating malfunctions by providing you with an overview of all components that make up a technical object. From this overview you can easily select the object for which you want to create a malfunction report. Furthermore, maintenance BOMs provide you with an over­

view of all spare parts used for the maintenance of a specific technical object, so they make spares planning considerably easier.

A maintenance BOM contains the object numbers of the individual components together with their quantity and unit of measure, and can be assigned to the master record of a technical object or material.

Reading Measuring Points and Counters and Creating Measure­

ment Documents

Measuring points and counters are located on technical objects. They help you document the condition of a technical object at a particular point in time and support you in perform­

ing counter-based or condition-based maintenance. Documenting the condition of a partic­

ular object is of great importance in cases where detailed records regarding the correct condition have to be kept for legal reasons. This could involve critical values recorded for environmental protection purposes, as well as measurements of emissions and pollution for objects of all types. If you perform counter-based maintenance, maintenance activities are always performed when the counter of the technical object has reached a particular counter reading. In the case of condition-based maintenance, the activities are triggered when the measuring point of a technical object has reached a particular state.

After a measurement has been taken at a measuring point or a counter, the data is stored in a measurement document. Based on that document the system calculates the next planned maintenance date and the call date on which a maintenance order is created. Each time you create a new measurement document, the system recalculates the planned date for the next maintenance work.

Accessing Context-Sensitive In­

formation

In functional locations and pieces of equipment quickviews appear as separate popups when you hover over an object, and provide relevant information about the superior techni­

cal object or the installed piece of equipment.

In technical objects you can open preconfigured side panels in a separate screen area and display context-sensitive charts and data. You can enhance the side panels to meet your requirements, thereby specifying which information you want to have displayed in the side panel.

Processing Master Data in the In­

formation Center

You can use the Information Center to search for functional locations and pieces of equip­

ment, and to call up technical objects from a personal worklist (POWL). Your personal worklist contains your favorites and objects that you have recently accessed or changed, and provides you with direct access to the Asset Viewer. You can personalize your worklist to your needs, sort table columns, and set filters.

Visualization of Technical Objects in the Master Data

With the SAP 3D Visual Enterprise Viewer, you can display graphics of technical objects right in the master data. You can display the graphic of the technical object as a thumbnail, as a 2D image or a 3D scene. In the 3D scenes, you can use various display functions, for example, you can pull the visualized model apart or rotate it, display a detailed view or a cross-section, as well as display associated parts lists.

Key Feature Use Viewing Technical Objects in the Asset Viewer

The Asset Viewer is a display tool that enables simple navigation through complex object relations and flexible navigation within and between objects. You can also view and navi­

gate the hierarchical structure of the technical object.
