Definition
Tools that you use to represent the wear and tear of an object, consumption, or the reduction of an object’s useful life are described as counters in the R/3 System (for example, the milometer for a vehicle, or an electricity meter for an electric-powered system).
In Plant Maintenance, counters are located on technical objects, in other words, on pieces of equipment or functional locations. For example, in the reservoir of a clarification plant, the volume of sewage that flows out of the drainage channels into this reservoir is measured in m3. The filtering tank is represented in the system as functional location C1-BR1. The waste water counter is designated as a counter 12 for functional location C1-BR1.
Counters form the basis for
counter-based maintenance.Use
Counter readings are taken at counters at particular intervals and in particular measurement units. For example, counter readings for kilometers driven or electricity used.
Counter readings describe a status at a counter at a particular point in time, and represent the transaction data for counters in the R/3 System. They are documented in the form of
measurement documents.Counters are a special form of
measuring point because over the course of time, counter readings only either continuously rise or fall. Counter overflow is also possible in the case of most counters. For example, a milometer can display a maximum value of 99,999 miles. Once this reading has been reached, an overflow occurs, in other words, the counter starts to count upwards from 00,000 again.Counter readings can be entered in the system in two different ways. In both cases, a qualitative valuation is made:
As with measurement readings, you can also enter a qualitative valuation for counter readings, using a valuation code (for example, 02.01.2000, 14.00, 48,200 miles, above-average increase of milometer reading.
You cannot make a solely qualitative valuation in the case of counters.
If you are dealing with counter-based maintenance, you can display the maintenance plans in which a counter is used in the master record of that counter. You have the following options for doing this:
