SAP PM Maintenance Processing

Chapter 2: Maintenance Notification Description

What is a Maintenance Notification?

A maintenance notification, PM notification for short, is used to describe the condition of a technical object in the PM System, to refer the maintenance department to a task that needs to be carried out and to document the work performed.

There are three types of maintenance notification in the standard version of the PM System:

  • Malfunction Report
  • Activity Report
  • Maintenance Request

Malfunction Report

A malfunction report describes a malfunction at an object, which affects its performance in some respect. Using a malfunction report, for example, an employee in Production can report that a system has reduced or zero performance, or that its output is of a reduced quality.

As a rule, a malfunction report requires the maintenance department to arrange for a specific repair task to be carried out, for the ideal condition of the object to be restored (according to DIN Norm 31051).

A special case of malfunction report is when a machine operator determines amalfunction, immediately repairs it and subsequently documents the malfunction thatoccurred, its effect and the way in which it was rectified. In this case, the maintenance notification is only entered after completion of the maintenance task as a completion confirmation.

Activity Report

An activity report describes a maintenance activity which has already been carried out, and which was not necessary due to a malfunction or a damage. It simply provides technical documentation that records which activities were carried out when, at what time and with what results. For this reason, activity reports are used for the technical confirmation of maintenance activities.

A typical activity report is the inspection findings, because it describes the results of an inspection carried out to test the actual condition of the object (according to DIN Norm 31051). The inspection measure was not requested specially using a malfunction report. In most cases, it is based upon an inspection order.

Another typical activity report is the maintenance findings. This documents the technical values of the object determined during and/or after regular maintenance work. These maintenance jobs are carried out in order to maintain the ideal condition of the object (according to DIN Norm 31051) and always result from maintenance plans.

Typical examples of the activities documented in activity reports are "Fill up oil" or "Check pressure" or "Tighten screws".

Maintenance Request

A maintenance request is a targeted instruction to the maintenance department to carry out an activity in the manner described. The decisive factor in this case is that there is no malfunction.

Maintenance requests are typically used for investments, for example if an employee requires a new monitor, or if all the telephones in one part of the building in a company need replacing.

What are the Functions of the Components of a Maintenance Notification?

A maintenance notification comprises the following components:

  1. Header Data
  2. Location and Account Assignment Data
  3. Item Data
  4. Task Data
  5. Activity Data
  6. Catalog Profile
  7. Breakdown and System Availability Data
  8. Schedule Overview

The individual data groups contain data that belongs together and which is grouped in its own screen.

Header Data

Each maintenance notification contains header data, that is, information which is used in identifying and managing the maintenance notification. It is valid for the whole notification, and comprises:

  1. number, description and type of notification
  2. required dates by which the activities requested should be completed and time at which the malfunction described began
  3. administrative data: the person(s) who created and who last changed the notification, date of entry and last change, name of person making the request, time of entering the request
  4. reference object: functional location and/or equipment and/or assembly to which the maintenance notification refers
  5. maintenance planner group responsible for processing the task
  6. notification status, which provides information on the stage of processing that the maintenance notification has reached

Location and Account Assignment Data

The location and account assignment data is copied from the master record of the reference object and is also valid for the whole PM notification. The location data provides information regarding the physical location within the company at which the functional location or equipment is situated. The account assignment data provides information as to how the maintenance costs are normally to be debited.

Item Data

In the notification item you enter and maintain data describing the problem or malfunction that has occurred, or the activity performed in greater detail. A notification can have several items. Each item contains the following data:

  1. short description of the malfunction arising (malfunction report) or the activity carried out (activity report), or the task to be carried out (maintenance request)
  2. exact component at a functional location, piece of equipment or assembly where the problem or malfunction occurred or where the activity was performed
  3. key or code for the problem that occurred and the cause
  4. short description of the cause
  5. classification of the notification or notification item
  6. key/code and short description of the activities performed

Task Data

Task data describes the tasks that need to be carried out in terms of planning and organization. Using tasks, you can plan the way in which various persons work together to process the notification and carry out the activities within a specified period of time.

Activity Data

Activity data documents the work performed for a notification. They are particularly important for inspections, as they are used as a record that particular jobs were carried out.

You can enter the following data for each individual activity:

  1. key/code for the activity performed
  2. short text to describe the code (this can be changed according to your requirements)
  3. start and end of the activity
  4. quantity factor for the activity

Activity data is displayed in various degrees of detail in the maintenance notification in the

  1. activity overview screen
  2. activity detail screen

You can maintain activity data both for the whole notification, that is, for the notification header, and for the individual notification items.

Breakdown and System Availability Data

This data describes the system breakdown and system availability determined before, during and after the malfunction. You can enter the following information here :

  1. start, end and duration of the problem or malfunction
  2. key for indicating whether the malfunction led to the reference object breaking down
  3. effect of the problem or malfunction at other parts of the system
  4. availability and condition of the system before and after the problem or malfunction occurred
  5. availability and condition of the system after the problem was solved or the malfunction repaired

Schedule Overview

The schedule overview displays all the dates that have been stored for the maintenance notification up to the current date in a single screen. These comprise:

  1. date and time the notification was entered
  2. date and time for start and end of the malfunction
  3. date and time for the required start and end of the activity
  4. date of the technical inspection and completion of the notification, plus reference date for the maintenance history
