A Manufacturing Execution System (MES) supports manufacturers in increasing their production performance and in achieving consistent growth in the global market.
An MES is seen to its full advantage if is integrated into existing Enterprise Resource Planning (ERP) solutions. A fully integrated MES solution, which is synchronized with the upstream and downstream processes, provides real-time information on all current and subsequent processes.
In the seamless interaction with SAP ERP, an SAP MES (SAP Manufacturing Execution System) provides cross-plant transparency from the management level to the manufacturing level.
For this reason, ME systems are installed directly below the ERP Level.
SAP MII acts as a vertical bridge for the exchange of information and data from the top floor to the shop floor in real time.
This enables the production processes of a company to be optimized and to become more dynamic. Due to the web-based technology of SAP Manufacturing Integration and Intelligence (SAP MII), contents can be shown on the desktop and also on mobile devices.
Predefined connectors based on open standards link manufacturing control computers with ERP systems and thus reduce costs, complexity, and time to value. A wide range of visualization and analysis tools supports Six Sigma initiatives and sustainably improves quality.
SAP Manufacturing Integration:
With its standard interfaces (IDoc, BAPI), SAP MII is an integration platform which serves as a vertical link between the management system SAP ERP and the production systems.
SAP Manufacturing Intelligence:
The intelligence function of SAP MII is used to create real-time analyses from the production data. With the transformation, processing, and visualization of production-related data and information, the integrated visualization tools can be used to map production key figures and alarms. A role-based user concept ensures that the information is visualized on the dashboard of the requester.
With SAP PCo (SAP Plant Connectivity), SAP offers a software component that enables data exchange between an SAP system and industry-specific standard data sources from different manufacturers. These include process control systems, operational historian systems, and SPC systems.
SAP PCo is therefore a high-performance communication interface from SAP, which ensures a bidirectional data connection between the production system and the SAP system.
The data from the source system can be transferred, event-triggered, to a target system (e.g. SAP MII, SAP Manufacturing Integration and Intelligence) and can also be transferred from the target system to the source system.
Due to its partition into source system, agent instance, and target system, SAP Plant Connectivity (SAP PCo) can be configured quickly and easily.
The agent instance provides a connection between the source and target systems. Within the instance, you can create any number of notifications, which are event-controlled based on the data basis.
Possible source systems are:
- OPC UA, OPC DA, OPC HDA, OPC A&E
- File Monitor Agent
- OLE DB
- GE Fanuc Proficy Historian
SAP OEE Management as an add-on, extends the standard functions of SAP MII (SAP Manufacturing Integration and Intelligence) to include numerous additional functions.
The data required to calculate the real-time Overall Equipment Effectiveness key figure (OEE) can be obtained from the production systems either manually, semi-automatically, or automatically.
Using SAP OEE Management, the main causes of production losses at plant level and across plants can be identified, and corrective measures can be initiated and monitored.
