SAP MII can be used to increase the visibility of energy and resource use in the production industry including temperature, pressure, water use, and more. This functionality can be used to collect and analyze data instantly from different points in the production data object hierarchy (plant, work center, equipment, machine, etc.). Subsequently, captured data can be periodically reported at the level of production event, tariff, and shift.el of production event, tariff, and shift.
The features and benefits of SAP MII Energy Monitoring are:
- Unnecessary consumption of resources is prevented.
- Data capture to optimization of energy use.
- Access to real-time and historical data.
- Shortening of the reporting process.
- A user-friendly interface.
SAP MII Energy Monitoring and Analysis UIs
Follow SAP MII Menu > Energy Monitoring and Analysis > Energy Configurations path to Energy Monitoring and Analysis screen.
The configuration processes consist of four parts:
- Production Event Templates
- Production Event Maintenance
- Shift Pattern Maintenance
- Tariff Maintenance
Production Event Templates
Production Event Templates are used to collect energy data at the production event level.
One of the ME, OEE, and Third-Party options must be chosen in the Template Type field. Next, a meaningful template name must be written in the Template Name field. Lastly, tables that will be used for collecting data must be chosen in the Source Table field. If the ”Relevant for Analysis” box is selected it means that the analysis will be related to the selection of this field. For the weighting of data collected, Weighting Factor must be selected for the preferred field. The ‘Property’ feature can be used to group.
P.S. If a ZTable is required, then the Third Party option must be selected in the Template Type field, considering that Third-Party selection only allows one table entry in the Source Table field.
Production Event Maintenance
Production Event Maintenance collects and reports production-related energy consumption data at the production event level.
After creating the Production Event Template, create an event with the Production Event Maintenance section. Enter a name in the Production Event Name field, select any template with Production Event Template field and select source database with Source Data Server field, and then save it. After saving, the created table includes the selected fields in the Database. The created table is shown in Fig. 3.1
N.B. If any production or process order status is active then, data will be recorded in the database.
Follow the MII Menu > System Management Scheduler path to create a new scheduler for transferring data to the created table. When creating a new scheduler, select Production Event in the Scheduler Type field, enter a name in the Name field, and then save it. (Fig. 3.2)
After creating a new scheduler, the Enabled checkbox should be marked in the Production Event Scheduler tab. Otherwise, the Scheduler will not be active. Enter the name of the table to which the data will be transferred in the Production Event Table field, and select the date to start the scheduler in the Start Date field. The required run time specification (second, hour, day, month) for the Scheduler must be entered in the Pattern field. Lastly, the Scheduler must be activated with the Run Job button. (Fig. 3.3)
Shift Pattern Maintenance
Shift Pattern Maintenance collects and reports production-related energy consumption data at shift level.
Follows the MII Menu > Energy Monitoring and Analysis > Energy Configurations > Shift Pattern Maintenance path.
A new Shift Pattern can be obtained by using the Create button. A template name must be entered in the Template Name field to continue. It is recommended to choose a meaningful name. In the Shift Schedule tab, the Schedule must be entered into the Schedule field from MII Menu > Data Services > Time Periods Schedules, and then the preferred date interval must be entered. (Fig. 4)
Follow the MII Menu > Data Services > Time Periods Schedules path to create a schedule. Next, the time interval created from MII Menu > Data Services > Time Periods must be assigned to the Schedule. (Fig. 4.1)
Tariff Maintenance is the collection of energy data used in the field of production, on a tariff level, to allow reporting on costs.
Follow menu path MII Menu > Energy Monitoring and Analysis > Energy Configurations > Tariff Maintenance .
On the Tariffs tab, a meaningful name should be entered in the Name field. Select a category for the Category field that was created with the MII Menu > Catalog Services > Category section. Unit of Measure is the determination of the ratio of energy units consumed in a specified price unit.
Unit of Measure = (Unit of Price / Unit of Energy)
e.g. $ / kWh
The valid date interval that you want to run is selected from the Validity Periods tab. In the Rates tab, since there may be different pricing tariffs at certain times of the day, the desired time is selected and the desired rate is entered in this time interval. Electricity charges may be high or low from time to time. The rates must be entered according to these time intervals.
For example, Rate 0.5 was entered because the electricity price may be low between 02:00 a.m – 05:00 a.m. A new tariff group is created with the Create button on the Tariff Groups tab. The Name and Description field should be completed with a meaningful name.
A category created on the MII Menu > Catalog Services > Category screen is selected for the Category field, and finally, the Tariff field is selected by choosing the tariff that was created on the Tariffs tab. (Fig. 5.1)
Configuration of Plant Information Catalog
The Plant Information Catalog records the logical hierarchy for a shop floor. It determines in which hierarchical structure it will collect data at the shop-floor level for SAP MII. The Plant Information Catalog objects can be mapped to Production Planning (PP) and Plant Maintenance (PM) objects in the SAP ERP system.
To use the Plant Information Catalog, it must be installed on SAP MII NetWeaver. First, the UserName, Password, Language, ServerName, and PortNumber fields are entered according to the ERP information for the Plant Information Catalog. Connection is made via http://IP:PORT/nwa > Configuration > Application Resources. An ERP-PIC connection is made on the SAP MII. (Fig. 6)
After the PIC connection is established, ERP Sources are selected via Plant Information Sources by following SAP MII Menu > Catalog Services > Plant Information Maintenance path to gain access to PM and PP hierarchies. (Fig. 6.1)
Once hierarchies are accessed, an existing hierarchy can be transferred or a new hierarchy can be created with the New button. After you determine at which hierarchy level the data should be collected, the properties of the SAP_Tariff and SAP_ShiftPattern are added and saved on the Property Set tab. (Fig 6.2)
Shift Pattern Maintenance and Tariff Maintenance name fields in the Energy Configurations section must be assigned to SAP_ShiftPattern and SAP_Tariff Property Sets’ Property Value field placed on the Properties tab at the level of Plant. (Fig. 6.3)
Self Service Composition Environment
Reports can be shown in the Self Service Composition Environment (SSCE) section. (Fig. 7)
N.B. Reports can be edited according to business needs.
