PROCESS MANAGEMENT

PURPOSE This component can be used to coordinate the exchange of production-relevant data between the R/3 System and the R/3independent production level. The production level can be controlled as follows: • Manually: the planned production steps are carried out manually by the process operator • Automated: the planned production steps are carried out automatically by the process control system • Partially automated: the planned production steps are carried out both manually by a process operator and automatically by a process control system

DATA FLOW - Overview

PROCESS FLOW- Overview

Process Instruction Process instruction contains the data to be fed to the external system or to the line operator. Process Message Process message is the output from the external system which will be the input for SAP to complete business transactions. Control Recipe Control recipe is the combination of Process Instructions through which the parameter are transmitted to the PI Sheet or to the PCS PI Sheet A sheet which have some process parameters on its display and will have editable fields which can be filled by the line operator according to the actual data.

You can store production-relevant data as process instructions in the process order. Once the process order has been released for production and has been saved, the production-relevant data is combined in control recipes and sent to process management. Process management receives the control recipes and sends them to the process operator or process control system responsible. If a control recipe is sent to a process operator, the production data stored in the control recipe is prepared as text that is displayed as PI sheets on the screen. The process operator can then use the PI sheet to execute the production steps manually. If a control recipe is sent to a process control system, the production data stored in the control recipe is sent as parameters to the production control system via the PI-PCS Interface. The process control system processes the data to control and regulate production.
