SAP DM - Device Management



        Device Management is fully integrated with the PM and MM and AM modules. A device (e.g.: meter, transformer) is a serial number of a device category and in the same time a piece of equipment. The device category is defined as a material in the material master.
This component manages technical data, Device Installation, meter readings, and the inspection of devices & certification of device, device technology.

         In the IS-U Device Management component, we can use IS-U-specific data and functions over and beyond the functions available in the R/3 Logistics application component. These include the following data and functions: ­-
         --Technical data, such as register group, input/output group, and command group
        --­ Installation as well as removal and replacement of devices in an installation
        --­ Installation  Structure for representing device and register relationships, and the rate data of     these devices
        --Organization and execution of meter readings in the supply area
        --­ Device inspection: sampling procedure, certification, and periodic replacement

Device category/device is essentially identical to the material/equipment, hence  all of the data and functions of the standard Logistics component are linked to Device Management module of ISU.
­         -- Inventory Management
        -- ­ Purchasing
        --­ Warehouse management
        --­ Plant maintenance
        --­ Classification system 

The device number is created in MM with the function Goods Receipt. At the utility company, the device is labeled with this number. The device number can also be generated when you create a device in IS-U. The device is identified by a unique material and serial number combination to distinguish it from other pieces of material that may have the same serial number. The equipment number is the same throughout the whole system.
