Configuring and Creating Measuring Points and Counters

It's possible to deactivate or activate several measuring points and counters at the same time in list editing for measuring points.

A measurement document is created to store the measurements/measurement readings for a specific counter or measuring point. Examples are a measurement document containing a measured pressure of 42 pascals or a measurement document containing a counter reading of 12,351 kilometers for a certain counter.

Enter data in the SAP system manually using the SAP user interface. You can also record measurement readings from a maintenance notification or maintenance order (fleet management).

Mobile applications such as SAP Work Manager or SAP Asset Manager enable you to enter data with mobile devices.

You can enter data using a barcode reader and copy it to the SAP system using the PM-PCS interface. The PM-PCS interface is an interface between the SAP system and external systems, such as process control system (PCS).

PCS data is created during the monitoring, control, regulation, and optimization of a technical process. You can copy this data to the SAP system using the PM-PCS interface.

For this purpose, you can use a Supervisory Control and DATA Acquisition (SCADA) system that filters data from the PCS and transfers only relevant data to the SAP system.

You can use various customer specific enhancements (for example, Customer Exits) to automate your business processes and, for example, automatically generate a malfunction report from a measurement document.

To simplify the entry of routine counter and measurement readings for several objects, a measurement reading entry list can be created as a master record. This list comprises different measuring points or counters for different objects.

When determining measurement readings or making counter readings, the respective values can be entered directly in this list. As before, the update occurs within a measurement document.

You have mapped an apartment building in the SAP system by means of a functional location hierarchy. A current meter represented by a barcode ID is assigned to each apartment and is read once per year. The technician who reads the meter enters the meter reading result in the barcode reader manually by using a block of numerals. Consumption building is performed in the SAP system, in the industry sector component Real Estate (RE), on the basis of the counter reading recorded. For information on the prerequisites you have to fulfill if you want to print barcodes with SAPscript, see Note 5196.

When preparing the work, you compile the measuring points and counters for the technician in the order of the round. In the SAP system, this compilation is shown as the measurement recording list. The technician first scans the barcode ID for each measuring point and counter using a barcode reader, and then enters the counter reading manually. After the round is ended, you transfer the data from the technician's barcode reader to the docking station using infrared signals. The barcode reader supplies the data that is copied to the SAP system using the PM-PCS interface. A measurement document is created for each measurement reading and counter reading. If you use the customer exit IMRC0001, the measurement document serves as the basis for a consumption billing in the industry sector component Real Estate (RE).

You can also use the catalog system to enter measurement or counter readings. The catalog system enables you to define permissible values for a measuring point that you can select using the catalog hierarchy when entering measurement readings. You can use this function when you want to predefine qualitative or descriptive measurement readings in the catalog system or if you want to use the following predefined values when entering counter readings:

• System reaction when the measurement reading is exceeded

• Permissible tolerance time for entering future measurement readings

For example, you have mapped a building, including the fire doors, in the SAP System using a functional location hierarchy. A measuring point represented by a barcode ID is assigned to each fire door. A meter reader checks each individual fire door once a month. The inspection result is usually Door OK, but this result should also be documented in the SAP System.

Possible damage can be shown clearly as valuation codes. The meter reader also enters these valuation codes by means of a barcode. Damage identified during the inspection automatically triggers a malfunction report in the SAP System.

The measurement documents can also be represented in a graphic form. You are connected to the Graphical Framework (GFW), which can be used to control various external graphic tools.

You can use the PM-PCS interface to transfer measurement and counter readings from external systems to the SAP system. The data is saved in measurement documents in the SAP system and can be used by both the Plant Maintenance and Customer Service components.

Performance-based preventative maintenance enables you to plan maintenance based on counter readings that are managed for the technical objects that need to be maintained.

You can use measurement documents to document the subject for system security, work safety, and environmental protection.

Possible external systems include the following:

• Mobile data entry systems

• PCS

• Building control systems

• SCADA systems

PCS provide a wide range of data for processes, buildings, or infrastructure. SCADA systems perform a filtering function; they filter out maintenance-relevant data, and thereby protect the SAP system from an excess of process data. In addition, SCADA systems are responsible for the communication between one or more PCS and the SAP system.

You can enter measurement readings collectively during order confirmation if measuring points are assigned to technical objects of a maintenance order or an operation. You can do this in the individual time confirmation (transaction IW41) by choosing the Measurement Documents from Object List option.

You need to activate Business Function LOG_EAM_CI_10.

Collective entry of measurement readings is also available for the web interface if you use the confirmation list of the technician. You can do this by selecting the Get Measuring Points from Object List button on the Measurement Readings tab.

For the web interface, you need to activate Business Function LOG_EAM_SIMPLICITY_9.
