Entering Measurement and Counter Readings as Barcodes 

Purpose

You use barcode readers for entering measurement and counter readings if:

The following scenarios illustrate the use of barcode readers.

Scenario 1: Barcode ID and Valuation Code are Scanned

You have represented a building in the R/3 System using a hierarchy of functional locations, including the fire doors. Each fire door is assigned a measuring point that is represented by a barcode ID. Once a month, each individual fire door is checked. Most of the time, the result of inspection is "Door is OK", but this inspection result should also be documented in the R/3 System.

The possible defects can be represented clearly using valuation codes. The valuation code is also entered in barcode form. Defects that are determined during the inspection must trigger the creation of a malfunction notification in the R/3 System.

Scenario 2: Barcode ID is Scanned, Counter Reading is Entered Manually

You have represented a block of flats in the R/3 System using a hierarchy of functional locations. Each flat is assigned an electricity meter that is represented by a barcode ID. The electricity meter is read once a year.

The meter reading cannot be entered as a barcode, but is instead entered manually by the meter reader using a key pad on the barcode reader. Consumption billing is performed in the industry-specific component Real Estate Management (RE) on the basis of the meter readings that are entered in the R/3 System.

Prerequisites

You need a barcode reader device with the appropriate transfer programs.

To be able to transfer the data from the barcode reader to the R/3 System, use the PM-PCS Interface. If you want to create automatically malfunction notifications for the measurement document, use the customer exit IMRC0001.

If you want to print out barcodes from the R/3 System using SAPscript, you can find out about the prerequisites for doing this in the Online Service System note 5196.

Process Flow

  1. You compile a list of the measuring points and counters in the sequence that they will be read in preparation for this to be done. This list is represented in the R/3 System as a measurement reading entry list.
  2. The person taking the readings first scans the barcode ID for each measuring point and counter with a barcode reader.
  3. In Scenario 1, the person taking the readings scans one of the valuation codes that is on their list.

    4. In Scenario 2, the person taking the readings enters the counter reading manually.

  4. After all the measurement and counter readings have been taken, you transfer the data from the barcode reader via infra-red to the docking station. The barcode reader supplies the data that is transferred to the R/3 System via the PM-PCS Interface.
  5. The R/3 System generates a measurement document for each measurement and counter reading.
  6. If you are using the customer exit IMRC0001, the system generates a malfunction notification in Scenario 1 for each measurement document that has one of the valuation codes predefined by you.

In Scenario 2, the measurement document forms the basis on which consumption billing is performed in the industry-specific component Real Estate Management.
