Various objects (called "Master data") are used in SAP/PM module to represent and describe technical installations
Functional Locations
Equipment
Assemblies
Bill of Materials / Materials
These data can be complemented using
Classification data
DMS (document management system)
Click on the headings in blue here below to get the details for each type of Master data.
1.1 Functional Location
Functional Locations
- allows to represent/describe technical installations (production units, laboratories, warehouses...) in SAP with a technical, geographical, process oriented approach.
are organized in a hierarchical structure according to functional, process-related or spatial criteria, so that upper levels functional locations in the hierachy represent large areas or main functions (a complete Production Unit with its differents sections/sub-sections) and can be detailed into smaller items, down to the level of individual locations / process functions (identified on the P&ID sheets by tag numbers, like a reactor, a vessel, a pump,…).
Each individual Functional Location represents a place/a process function at which maintenance tasks can be performed.
Functional Locations structure is the backbone of the Maintenance information system. It allows to organize most data used in Maintenance (technical documentations, procedures, breakdowns, costs...)
Techinical objects (Equipment) can for example be installed at Functional Locations, in order to describe the physical devices used to fulfill the process function identifed by the Functioal Location.
1.2 Equipment
A piece of Equipment identifies an individual physical device / machine in the technical installations (a reactor, a pump, a motor ...), which is maintained independently. Equipment are generally installed on a Functional Location, and can - during its lifetime - be moved to different locations.
Using Equipment allows you to perform the following functions in the system:
- manage individual data from a maintenance perspective for each individual machine/device : general information, technical characteristics, instructions for maintenance...
- record individual maintenance activities for each piece of Equipment, to be planned (Maintenance Plan) or at each breakdown
- keep historical information of all the maintenance tasks performed for a technical object.
1.3 Assembly
Assemblies are used
- to define - in a generic manner - the main basic components of a category of Equipment. For example for pumps: impeller, shaft, coupling,... At each breakdown of a piece of Equipment, it will allow to specify the part which is damaged.
- to organize long bill of materials in sub-sections, so that each Assembly will regroup spare parts logically ; for example those for a specific part of a type of Equipment (eg. spare parts for the shaft in a Pump).
1.4 Materials and Bill of Materials
Materials are used in SAP to describe spare parts used in Maintenance.
A bill of material (BOM) is a complete, formally structured list of the components (spare parts) making up a technical object or an Assembly. It contains the material numbers of the individual components together with their quantity and unit of measure. The components can be stock or non-stock spares.
Bill of Materials
- can be specific to a Piece of Equipement or a Functional Location, or can be generic (for example : for all pumps of a specif model)
- can be organized in a structural way (using Assemblies) so that each Assembly in a level allows to define a sub-level grouping spare parts specific to the Assembly.
Maintenance BOMs are used to easily identify the appropriate spare parts when repairing a piece of Equipement or a Functional Location.
1.5 Task List
Maintenance Task Lists describe the sequence of individual maintenance activities which must be executed in a repair or maintenance job.
Task lists can be specific to a Piece of Equipement, to a Functional Location, or can be generic (General Task List).
Task list are useful for repetitive jobs, they allow to easily create the work order used to carry out each individual repair/job. They are mostly used in planned maintenance, but can also be used in regular (unplanned) maintenance.
1.6 Document Management System
The Document Management System (DMS) allows
- to store / link any kind of document (Drawing, procedure, pictures,...) in SAP,
- to define the main properties of these documents ( description, owner, status….), allowing to sort and search them easily
- to link these documents to various objects (Equipment, Functional locations, Materials...)
The documents can either be located (stored) on a shared drive, in an External application, on Internet or in the SAP database (vault).
The DMS allows for example
- to store/identify all technical documents related to an Equipment (eg. Technical repair manual, procedure for inspection...) for easy retrieval/access during a repair
- to store any kind of information related to Maintenance activities (Inspection reports...)
1.7 Classification System
The classification system allows you to use characteristics to describe all types of objects, and to group similar objects in classes. You then use the classes to help you to find objects more easily, using the characteristics defined in them as search criteria. This ensures that you can find objects with similar or identical characteristics as quickly as possible.
